* Centers of excellence <strong>for</strong> brush rolls!
High quality raw materials, years of experience, modern manufacturing<br />
techniques, and careful workmanship. These are<br />
important criteria which ensure the consistently high quality<br />
of OSBORN products. Quality assurance accompanies all<br />
stages of production. It is fully integrated into the processes<br />
and certified in accordance with DIN EN ISO 9001-2000. This<br />
has made us the world’s #1 supplier in brush technology, but<br />
we are not satisfied with that. Constant innovation and product<br />
development are of central importance to us, both inhouse<br />
and in close cooperation with technology partners in<br />
Europe, Asia and North America. We seize the goal of making<br />
our range of services, and with it the products and processes<br />
of our customers, better, faster, safer, more reliable and more<br />
environmentally friendly.<br />

2.1<br />
Brush roll applications<br />
Degreasing, washing and cleaning<br />
The demands relating to the quality and the technical product<br />
characteristics of flat rolled steel in the <strong>for</strong>m of cold<br />
rolled steel, tin plated steel, electrical steel, galvanized strips<br />
or other refined surface materials are steadily rising. Along<br />
with increasing processing speeds, optimising the tempering,<br />
refinement or coating process of the upstream strip<br />
cleaning section also increases.<br />
comparison to conventional brush rollers. HDL ® sets new<br />
standards in the degreasing and cleaning of strip surfaces.<br />
Through the consistent development of quality, by looking<br />
at fill material, brush construction and fill density, we<br />
achieve significant improvements in terms of the brush lifetime<br />
/ cleaning per<strong>for</strong>mance. This results in reduced operating<br />
and maintenance costs <strong>for</strong> our customers.<br />
With the development and introduction of the HDL ® brush<br />
roller, OSBORN has found an answer to these demands, in<br />

OSBORN HDL ®<br />
<strong>Technology</strong><br />
OSBORN HDL ®<br />
- a new benchmark in strip cleaning<br />
Customers’ needs depend on the type and degree of soiling<br />
of the primary material as well as on the strip cleanliness<br />
required <strong>for</strong> the subsequent process step. While optimum<br />
degreasing and micro-cleaning may be achieved with nonabrasive<br />
multi-filaments, abrasive filaments are ideally suited<br />
<strong>for</strong> the removal of strongly adhesive rolling retentions from<br />
the previous rolling process.<br />
5<br />
OSBORN HDL ® brush rollers are there<strong>for</strong>e individually tailored<br />
to the relevant case in hand. At the same time, multi-filaments<br />
and special mono-filaments can be used with or without<br />
an abrasive load as single bristle or mixture filaments.
Besides brush rollers <strong>for</strong> degreasing and cleaning applications,<br />
OSBORN offers a series of other innovative products<br />
and solutions <strong>for</strong> cleaning sections of strip lines:<br />
• LOAD RUNNERS ® ensure a durable and maintenance-free<br />
function of roll exchange vehicles.<br />
• Temperature and alkaline resistant brush seals provide<br />
optimum splash protection on the strip inlet and outlet of<br />
individual machine elements.<br />
• Vacuum squeezing systems set new standards in the complete<br />
drying of strip edges. It is possible to replace the hot<br />
air dryer altogether, resulting in enormous energy savings.<br />
• In the modernisation of strip lines, it is possible, through the<br />
integration of optimised brush machines instead of the old<br />
line, to create additional space <strong>for</strong> further improvements to<br />
the line. This is achieved by the compact design as well as an<br />
improvement in cleaning efficiency.<br />
• NOVOTEX ® squeezing rollers complete the OSBORN strip<br />
cleaning range. Compared to conventional rubber or<br />
polyurethane rollers, these non-woven rolls offer a number<br />
of beneficial product characteristics, such as significantly<br />
better coefficients of friction, material compression or cut<br />
and wear resistance. This in turn ensures longer durability,<br />
improved squeezing results, prevention of aquaplaning<br />
and reduction of damage to the strip.<br />

Brush roll applications<br />
Activation of strip surface<br />
The activation of the strip surface is an important task both<br />
in the production of rolled claddings as well as in the coating<br />
and/or finishing of strip steel, tinplate, electrical steel<br />
strip and other materials. In rolled cladding, the core and, if<br />
necessary, the overlay strips or plates have to be freed initially<br />
from oil, grease, dirt, carbon particles and oxides. This<br />
is done with the help of brush rollers in alkaline cleaning or<br />
acidic pickling processes.<br />
In the next process step, an activation of surfaces then takes<br />
place by generating a defined roughness using abrasive or<br />
wire brushes. A similar process also happens in continuous<br />
strip coating. In both cases, an optimal adhesion is guaranteed<br />
<strong>for</strong> the subsequent rolled cladding and/or organic or<br />
metallic coating through surface activation.<br />

<strong>Technology</strong><br />
OSBORN HDL ®<br />
- micro cleaning plus surface activation<br />
Here too, HDL ® rollers from OSBORN create an ideal combination<br />
of the different brush functions needed by our customers.<br />
The non-abrasive multi-filaments ensure optimum<br />
micro-cleaning as the abrasive filament mechanically intensifies<br />
its abrasive effect and at the same time generates the<br />
required surface activation. The grinding agent, grain size,<br />
face density and abrasive content are also individually adjusted<br />
to the respective individual application.<br />
OSBORN has devoted itself to this challenge <strong>for</strong> years. We<br />
have strategically maneuvered ourselves to be the premier<br />
producer of brush rollers through the development of innovative<br />
microfilaments and brush constructions as well as the<br />
preservation of high quality standards.<br />
In steel sheet coating, the brush roller has long been promoted<br />
as an absolute high-per<strong>for</strong>mance and precision tool in the<br />
case of thicknesses of < 0.15 mm, coating thicknesses of 0.05<br />
g/m² and even higher line speeds. At the same time, the individual<br />
demands made on the brush depend on the flatness,<br />
surface hardness of the starting material and the nature of the<br />
subsequent coating or plating.<br />

Brush roll applications<br />
Roll cleaning and polishing 2.3<br />
OSBORN’s Helimaster brush rolls are perfect <strong>for</strong> cleaning<br />
work and as back-up rolls in wet or dry operated rolling and<br />
skin-pass mills. They have been fitted to technological developments<br />
worldwide <strong>for</strong> decades, both in online lines integrated<br />
in strip lines as well as stand-alone off-line rolling<br />
stands.<br />
The rollers can work sporadically or continuously when<br />
designed as a wire or an abrasive brush. Each brush is neutrally<br />
ground at the radius and gets axially. This means that it<br />
gets either a cylindrical camber ground or, <strong>for</strong> offsetting the<br />
computed roll deflection, a positive and/or negative camber<br />
ground.<br />
In the meantime, with Lipprite ® abrasive rollers, an alternative<br />
technology, has also been developed and manufactured inhouse<br />
<strong>for</strong> skin-pass roller cleaning.<br />

The brush roller itself is only part of<br />
the solution. This technologically demanding<br />
application can only be optimally implemented with a precise<br />
matching of the brush tool to operational and process parameters.<br />
The reproducibility of the specified corrosiveness and<br />
brush effect as well as constant tool per<strong>for</strong>mance play a crucial<br />
role from the first point of use to the exchanging of the<br />
roller.<br />
Roll cleaning in a typical skin-pass mill<br />
For the cleaning of deflector, shape control or thickness measurement<br />
rolls, special wear-resistant non-abrasive plastic filaments<br />
are used. They ensure an equally thorough removal of<br />
solids and liquid materials without damaging the roll surface<br />
or altering the roughness. At the same time, the filament type<br />
and bristle diameter are dependent on the surface hardness<br />
and the degree of pollution of the roll that requires cleaning.<br />

Strip polishing and finishing<br />
When it comes to the optical finishing of strip surfaces in<br />
the <strong>for</strong>m of polishing, satinising, finishing or decorative<br />
grinding and brushing, you’re in good hands with OSBORN.<br />
Decades of experience in the machining of steel, stainless<br />
steel, aluminium and other non-ferrous surfaces have given<br />
us a technological advantage, from which our customers<br />
benefit worldwide today.<br />
In addition to high-quality wire and abrasive brushes, we<br />
can also rely on a merger with the Lippert-Unipol Group,<br />
one of the global leaders in abrasive and polishing tools, if<br />
necessary. We can combine polishing and abrasive rollers<br />
as well as polishing compounds on a selection / combination<br />
of tools and processing alternatives. This is unique in<br />
the market, which gives you the advantage of the most<br />
optimal surface finishing in your application.<br />

Today, increasingly higher demands are made on the final<br />
machining of strips. An optically perfect and homogeneous<br />
surface over an entire field of vision achieved through the correction<br />
of small surface defects in the last mechanical machining<br />
step is in high demand. This applies equally to the operators<br />
of strip lines as well as <strong>for</strong> service centres or direct<br />
processors of coils.<br />
Different types of rollers and coatings can also be used<br />
depending on the material type and quality, the surface hardness<br />
and the required finish and condition be<strong>for</strong>e the final finishing.<br />
For determining the respective optimum tool, we<br />
carry out individual pilot tests at test lines in our laboratory.<br />

A combination of Bessemer wire roller brushes and polishing<br />
emulsions is used in the removal of oxide layers and polishing<br />
cold rolled uncoated strips after annealing re-crystallisation.<br />
Both components come from OSBORN-UNIPOL and are<br />
specifically matched to individual surface requirements.<br />

UNIPOL ® polishing emulsion<br />
(liquid emulsion application)<br />
UNIPOL ® polishing emulsions are initially applied directly to<br />
the strip surface to be processed as a liquid paste in immersion<br />
baths or by means of a low-pressure, medium-pressure,<br />
high-pressure or airless spraying system.<br />
With Bessemer wire measuring diameters of 0.06 or 0.08 mm,<br />
filled rollers serve as carriers of this paste in the subsequent<br />
polishing process.<br />
Our Lipprite ® product series represents an alternative to<br />
brush rollers with a wire or abrasive bristle coating. As with<br />
grinding non-woven rollers, an absolutely uni<strong>for</strong>m fine final<br />
grind and a corresponding homogeneous surface finish can<br />
be achieved. With the correct contact pressure, the flexible<br />
roller surface is in a position similar to a brush to offset any<br />
slight unevenness of the strip.<br />

Brush roll applications<br />
Scale removal<br />
For de-scaling strip surfaces after hot and cold mill processes,<br />
our brush rollers have been setting standards <strong>for</strong> years.<br />
OSBORN’s developments and innovations in both brush constructions<br />
and filaments have in set the international standards<br />
in annealing and pickling lines or bright annealing lines<br />
<strong>for</strong> stainless steel strip.<br />
With the development of acid resistant fill materials, it has<br />
been possible to achieve tremendous quality and improvements<br />
relating to service life on numerous strip lines. This<br />
results in substantial reduction of total cost <strong>for</strong> our customer.<br />
The parallel optimisation of the brush / shaft design and operational<br />
parameters through targeted assistance on site is<br />
another important OSBORN competence based on our longstanding<br />
worldwide experience.<br />

A new brush-generation - acid proof filaments<br />
Through the development of special abrasive and non-abrasive<br />
facing materials combined with an improved level of acid<br />
resistance and excellent wearing properties, the lifetime of<br />
brush rollers in stainless steel strip lines has now been significantly<br />
increased. This allows tremendous cost savings in<br />
the <strong>for</strong>m of longer lifetimes and lower maintenance costs.<br />
Ideally, the abrasive rollers are inserted on roller systems<br />
made from hollow shafts with bore holes. Apart from<br />
improved cooling of the filaments in the continuous operation<br />
of the roller, these also provide continuous rinsing out of<br />
acid or other corrosive mediums from the brush lining. An<br />
11<br />
optimum rinse function is ensured on one hand by the correct<br />
number and size of the cooling holes and on the other hand<br />
by the amount of liquid.<br />
At the downstream strip drying operation, similarly significant<br />
process improvements and substantial cost savings can<br />
be achieved through the use of squeezing rollers, which are<br />
made of newly developed, acid-resistant, non-woven materials<br />
or through the use of vacuum systems.
Where stainless steel materials reach their limits in high acid<br />
concentrations, special protective coatings on shafts and<br />
accessories provide the optimal protection of these components.<br />
In addition, steel shafts with shock and impact resistant coatings<br />
provide cost benefits as they are an interesting alternative<br />
to stainless steel bodies.<br />
In manufacturing stainless steel flat products, OSBORN<br />
International’s intelligent solutions and innovations play a<br />
part in process optimisation and quality improvement as well.<br />

Roll coating control<br />
Almost 50 years ago, OSBORN developed a revolutionary<br />
technology using brushes in the continuous rolling process<br />
in order to optimally regulate the oxide film on working and<br />
back-up rollers in hot rolling mills. As a result hundreds of<br />
hot mills worldwide have been equipped with OSBORN<br />
technology.<br />
To date, specially designed wire qualities, abrasive multifilaments,<br />
individually camber ground surfaces and extensive<br />
experience in optimising the use of brushes in numerous<br />
individual applications have secured a major technological<br />
advantage <strong>for</strong> us in this field. The benfits from this<br />
we can pass on to our customers worldwide.<br />

uni<strong>for</strong>m brushing across the entire width of the<br />
roll. Depending on the construction of the working or backup<br />
rollers to be brushed and the calculation of the optimum<br />
crown, convex or concave contours are ground. OSBORN,<br />
of course, also grinds brush rollers with a CVC contour on<br />
CVC technology mills <strong>for</strong> roller gap adjustment.<br />

Brush roll applications<br />
Transport roll systems <strong>for</strong> HHT furnaces<br />
The tempering of hot mill plates made of precipitation hardening<br />
aluminium alloys through the process of solution<br />
annealing, serves the purpose of attaining higher strength<br />
and strain values along with a good level of corrosion resistance.<br />
Today, this is required <strong>for</strong> structural parts in aircraft in<br />
accordance with the strict requirements of standards AMS<br />
2750D, AMS 2750C and AMS-H-6088.<br />
The careful transportation of these aluminium plates in ‘hard<br />
metal and hard material technology’ roll hearth furnaces<br />
takes place as a batch or continuous process at temperatures<br />
of up to 600°C on brush transportation rolls. In close cooperation<br />
with leading equipment manufacturers, numerous furnaces<br />
around the world have been equipped in recent years<br />
with OSBORN’s sophisticated technology. In the process,<br />
plates with thicknesses of up to 400mm, lengths of 20 metres<br />
and weights of over 10 tonnes do not present a problem <strong>for</strong><br />
us. Tolerances have been continually reduced and product<br />
features optimised, so that now more than ever, the brush<br />
roller is an integral and technologically superior component<br />
in the overall design of the line.<br />

Surface-sparing plate tracking with longstanding roll lifetimes<br />
With brush furnace transportation rolls, OSBORN customers<br />
can today place their trust in several decades of experience<br />
and well known global references. In the complex production<br />
of the rolls, some with a total length of over 6000mm and<br />
4000mm of brush length, the highest level of precision and<br />
reliability are required in all manufacturing processes.<br />
After the rolls have been manufactured, the later course of<br />
the sheet is accurately simulated in advance in our factory.<br />
For roll assemblies in new furnace lines, this allows OSBORN<br />
15<br />
to guarantee an optimum course of the sheet within tight tolerances<br />
even when starting up the run.<br />
In order to guarantee the lowest possible sheet tracking with<br />
the ‘re-brushing’ of entire furnace zones the transportation of<br />
the sheets is simulated on an in-house test rig just like new<br />
lines.
This advanced technology provides a convincing argument<br />
<strong>for</strong> why brushing with heat resistant wires is increasingly<br />
establishing itself as a roller cover <strong>for</strong> furnace transportation<br />
rolls.<br />
• Optimum heat transfer between the transportation roll and<br />
the plate<br />
• Longstanding lifetime without significant wear of the brushes<br />
• Complete avoidance of scale pick-up and spot <strong>for</strong>mation<br />
on the surface of the roller, just as it is the case with selfcontained<br />
roller coverings<br />
• Total-care transportation of the plates during the heat treatment<br />
without damaging the surfaces of the plates<br />
Aside from the production of new rolls, the recovering and<br />
replacement of worn brushes in older lines is also one of our<br />
core competences.<br />
By precisely measuring the course of the plate as well as the<br />
state of the individual rolls within the furnace by means of<br />
self-developed test equipment, we are able to optimise plate<br />
tracking if needed, which maximizes the output of the entire<br />
system.<br />

Brush roll applications<br />
Transport roll systems <strong>for</strong> noise reduction 2.9<br />
When transporting the sheets onto rolling tables, extreme<br />
noise levels may occur in slitting/cross cutting lines by heavy<br />
plates after the shearing process. At over 110 dB, this may<br />
possibly exceed the threshold of noise pain <strong>for</strong> the human<br />
ear.<br />
By coating the bright transport rollers with brush sections,<br />
the noise level can be reduced to around 70 dB so that any<br />
health risk to the labor <strong>for</strong>ce is significantly reduced.<br />

undergoes a professional inspection in accordance to the<br />
agreed upon service contract. The condition as well as the<br />
time and expense involved with the maintenance are documented<br />
with the aid of standardised protocols.<br />
The quiet and low-vibration running of the rollers is important<br />
in order to avoid shatter marks or shading on the strip<br />
surface caused by the brush roller. Be<strong>for</strong>e recovering, each<br />
shaft is there<strong>for</strong>e examined with regard to inbalance and concentricity<br />
deviation, in order to align it straight if necessary<br />
and to rebalance it.<br />
The longer the service life of rollers, the more important it is<br />
to have the proper condition of the bearings to avoid additional<br />

Adaption/improvement of existing rolls/shafts<br />
OSBORN HDL® - the benchmark in lifetime and brush per<strong>for</strong>mance<br />
OSBORN HDL ® provides even more than this. What we mean<br />
by this concept is an optimisation approach to strip lines in<br />
regard to the various brush applications as well as the working<br />
parameters of these rollers.<br />
In the first step to find a solution <strong>for</strong> you, we will analyze the<br />
current fine weaknesses. Depending on the type of line and<br />
degree to which the brushes are required <strong>for</strong> cleaning,<br />
degreasing and surface activation, an individual covering is<br />
25<br />
defined <strong>for</strong> the roller. This covering is made from non-abrasive<br />
and/or abrasive micro fibres and monofilaments. Parallel<br />
to this, the shaft construction is optimised and adjusted. In<br />
general, the customers’ existing shafts can be used. The<br />
usage parameters of the respective brush rollers are evaluated<br />
with regard to cooling, in-feed and revolution speed. We<br />
then draw up a customized optimisation recommendation.
Compared to conventional standard brushes, OSBORN HDL ®<br />
rollers offer decisive advantages:<br />
Micro filaments improve strip cleanliness<br />
• Significantly increased lifetime and reduced operating,<br />
maintenance and overall brush costs<br />
• Improved cleanliness levels in strip cleaning, contributing<br />
to quality improvements, process optimisation and<br />
increases in line speed<br />
• Targeted and better control of the rollers due to the compact<br />
design with higher density make a significant contribution to<br />
reliability and a controlled process<br />
Unlike conventional mono-filaments with bristle diameters<br />
ranging between 0.15 and 1.5 mm, our Novofil micro-fibre<br />
material can also reach rough depths of strip surfaces. This is<br />
due to their very thin thread thicknesses of up to 0.02 mm,<br />
which brings with it significantly improved cleaning and<br />
degreasing levels. In the process, a multi-filament bristle can<br />
be made from several hundred micro fibres.<br />
Due to the extremely high density and the individual mix with<br />
new, especially hard and rigid abrasive materials, heavy soiling<br />
and coarse metallic rolling retentions are removed in a<br />
way which is better than ever be<strong>for</strong>e.<br />

In the process, Lipprite ® abrasive rollers represent an alternative<br />
to brush rollers in various applications. Besides finishing<br />
applications, they are used <strong>for</strong> working-roll cleaning, <strong>for</strong> surface<br />
activation, as well as <strong>for</strong> de-scaling.<br />

Lipprite ® abrasive rollers are manufactured<br />
from abrasive non-woven<br />
flaps through radial adhesion to a<br />
core. The abrasive grinding grain<br />
made of silicon carbide (SiC) or aluminium<br />
oxide (Al2O3) is, at the same<br />
time, embedded into the surface of<br />
the random web fibre non-woven<br />
material (made of polyamide or other synthetic material) by<br />
means of resin. The corrosiveness of the roller is individually<br />
determined by the density of the material, i.e. the number of<br />
flaps.<br />
An optional additional impregnation makes the roller even<br />
more aggressive and increases the life span. It is necessary to<br />
keep in mind, however, that because of the significantly<br />
increased hardness, impregnated rollers are less flexible. As<br />
such, surface undulations can be harder to balance, which<br />
may result in a less uni<strong>for</strong>m finish or, in terms of the machining<br />
profile, visual shading.<br />
Technical data and product characteristics:<br />
• max. roller width 2000mm<br />
• max. roller diameter 450mm<br />
• Versions available with or without impregnation<br />
• Rollers are dynamically balanced in accordance with DIN<br />
EN ISO 1940<br />
Recommendations concerning the use of rollers:<br />
• Use in wet or dry operations<br />
• Optimum cutting speed 15-25m/s<br />
• Line (strip) speed or feed speed up to 30m/min. (max.)<br />
• <strong>Processing</strong> in the opposite direction to the running direction<br />
of the material feed<br />
• Optimum depth of immersion 2-6mm, depending on the<br />
roller diameter and hardness<br />
• Oscillation improves the uni<strong>for</strong>mity of the machining profile<br />

NOVOTEX ®<br />
non-woven rolls<br />
Products and applications<br />
Strip lines and rolling mills are equipped with a large number<br />
of different rolls <strong>for</strong> completely different tasks and applications.<br />
Through ever-higher line speeds and steadily increasing<br />
demands in terms of quality and process reliability, the<br />
demands made on roll covers and surfaces also increase. As<br />
such, non-woven rollers, with their special material properties,<br />
become increasingly important within the steel, aluminium<br />
and non-ferrous metal industry.<br />
Through close cooperation with one of the world’s leading<br />
manufacturers of technical non-woven materials, OSBORN<br />
has managed to develop a highly-engineered series of products<br />
under the NOVOTEX ® brand name, which are able to fully<br />
satisfy our consumers’ expectations in terms of quality, reliability,<br />
and durability at an excellent price/per<strong>for</strong>mance ratio.<br />
NOVOTEX ® - convincing in quality and profitability<br />
Material properties and technical benefits<br />
OSBORN’s NOVOTEX ® rollers are used where other synthetic<br />
roller coatings reach their limits and can no longer ensure<br />
optimum results or stable processes. Compared to rubber or<br />
polyurethane, non-woven material offers crucial advantages:<br />
• The porous structure of non-woven fabric in combination<br />
with a large pore volume makes the material compressible<br />
• It is significantly easier to avoid aquaplaning effects<br />
• Through the applied pressure of the random web on a roller<br />
core, a roll coating results which, with a hardness of up to 95<br />
shore A, exhibits an enormous resistance to being cut as<br />
well as a ‘self-healing’ effect in the event of light cuts<br />
• The capillary or suction effect when discharging the nonwoven<br />
structure provides a significantly lower amount of<br />
residual moisture in squeezing applications<br />
• In contrast to elastic, but hardly compressible rubber or<br />
polyurethane coatings, a significant adhesion effect occurs<br />
in the contact area of the strip surface that is under pressure.<br />
Taking these roll coverings into consideration, this is<br />
something that leads to significantly higher and more constant<br />
coefficients of friction.<br />
1 mm 1 µm<br />
29
• This results in excellent wear characteristics with a much<br />
higher roll lifespan in comparison to rubber or polyurethane<br />
• Due to its pore volume, the roller covering is in the position<br />
to absorb small particles of dirt, oil or grease residue<br />
as well as light roller tinsel<br />
• For a sustained period, the surface itself remains largely<br />
free of contamination or hardened material - an important<br />
criterion <strong>for</strong> permanent, reliable roll operation without fluctuations<br />
in quality<br />
• In addition, the strip surfaces are particularly conserved<br />
and protected from damage<br />
Economic benefits<br />
The material properties and technical benefits described<br />
bring about a series of economic benefits, which make the<br />
use of non-woven fabric rolls a viable option from a cost/benefit<br />
point of view:<br />
Material compressibility of non woven<br />
• Despite high acquisition costs <strong>for</strong> the individual rolls, the<br />
longer service life ensures a reduction in operating costs<br />
that significantly outweigh the initial costs.<br />
• Significantly longer lifespans <strong>for</strong> the rolls reduce downtime<br />
and thus, reduce maintenance costs<br />

The roll deflection is of crucial importance <strong>for</strong> an optimum and<br />
uni<strong>for</strong>m squeezing result over the entire width of the strip. This<br />
is especially the case in weak or undersized shaft constructions.<br />
When the feed <strong>for</strong>ce is too high the roll ‘whips’ leading to<br />
excessive residual moisture in the central area, where as too<br />
little feed <strong>for</strong>ce causes wet edges on border areas.<br />
For this reason, OSBORN International defines the optimal<br />
feed <strong>for</strong>ce <strong>for</strong> each non-woven roll and, on this basis, works<br />
out the expected roller deflection. The roll crown will be<br />
ground to either convex or concave contours.<br />

Applications<br />
Pressure rolls<br />
S-rolls / Tension rolls /<br />
Bridle rolls<br />
Squeezing rolls<br />
When used as bridle rolls, tension rolls, steering rolls or<br />
deflector rolls, the advantages of non-woven fabrics over<br />
other synthetic coatings are especially clear. In a dry state and<br />
especially in wet conditions, a non-woven fabric has an excellent<br />
and above all constant friction coefficient both on oil as<br />
well as on watery mediums.<br />
The friction coefficients of rubber or polyurethane-coated<br />
rollers, however, are very low; something which can easily<br />
lead to aquaplaning in the case of non-driven roller, e.g. a<br />
floating of the roller. This can result in strip slippage, which<br />
causes scratches and damage to the surface. On the other<br />
hand, non-woven coatings adhere well to the strip surfaces.<br />
This allows much higher tensile <strong>for</strong>ces to be achieved, and<br />
strips can be held tightly and controlled much more accurately.<br />
Even when applied to braking or tension rolls, the material<br />
properties speak in favour of the non-woven roll. Because of<br />
the strong and stable adhesion between the roll and the strip<br />
surface, strips can be evenly pulled or control-braked even at<br />
high plant speeds.<br />
Deflector rolls<br />
Squeezing rolls ensure lower residual moisture than rubber<br />
or polyurethane coatings. On account of the capillary or suction<br />
effect of the non-woven material, fluid displacement at<br />
the edges is reduced, and the strip edges dry better. In addition,<br />
the special properties of non-woven materials prove<br />
their worth in terms of resistance to cuts and durability.<br />
Transport rolls /<br />
Carrying rolls<br />
Tension rolls /<br />
Brake rolls<br />
As oiling or applicator rollers, non-woven coatings ensure the<br />
uni<strong>for</strong>m application and distribution of liquid coatings<br />
because of their sponge effect. Due to their porosity and pore<br />
volume, they are in the position to absorb liquid and, under<br />
pressure, to dispense it again evenly and/or to distribute it on<br />
the surface.<br />
The special surface protection, which is created by absorbing<br />
small dirt particles into the roller surface, is visible in pressure<br />
rollers made of non-woven material especially <strong>for</strong> soft and<br />
sensitive surfaces such as aluminium e.g. coil strips in cold<br />
rolling processes. Line speeds of over 1000m / min present<br />
no problems.<br />
Applicator rolls<br />
A similar situation applies to the use of a non-woven roller as<br />
a transporting or carrying roll. The soft and absorbent surface<br />
of the roll prevents scratches or damage, thus ensuring the<br />
smooth transfer of the strip.<br />

<strong>Innovative</strong> equipment technology<br />
Vacuum squeezing systems<br />
By connecting a pair of squeezing rolls made from special<br />
micro fibre – non-woven material with simple vacuum technology<br />
– we are able to offer an innovative, energy-saving<br />
and environmentally-friendly system <strong>for</strong> strip drying in a variety<br />
of process lines. Through this technology, which has been<br />
proven and established in Japan <strong>for</strong> decades, it is sometimes<br />
possible to replace entirely a fan or hot-air dryer. As a result,<br />
a single line can achieve annual energy savings of up to EUR<br />
100.000.<br />

Dry surfaces and very low energy consumption without hot air<br />
The function of the system is simple. The vacuum generated on<br />
the perimeter absorbs the liquid remaining on the strip surface<br />
into the roll supported by the capillary action of the micro fibre<br />
non-woven covering. Through the hollow shaft on its perimeter,<br />
which has numerous holes on it, fluid is sent via the vacuum<br />
pump to the existing fluid circuit.<br />
Significant quality and process-related optimisation is created<br />
through the vacuum technology with absolute dry strip edges as<br />
just an example. Displacement through the gap in the squeezing<br />
rollers on the edge area is eliminated entirely by the strong vacuum,<br />
and moreover, the need <strong>for</strong> subsequent expensive/laborious<br />
drying is completely removed.<br />
35
Microfibre squeezing rolls in combination<br />
with energy saving vacuum technology<br />
The advantages of the vacuum roller especially become more<br />
relevant in comparison to conventional squeezing rollers on<br />
shatter plates or extremely rough strip surfaces.<br />
OSBORN rolls function with a very soft surface and only minimal<br />
contact pressure. As such, the coating is significantly<br />
less prone to wear and essentially more resistant to damage<br />
from strip edges than in the case of traditional squeezing<br />
rolls. Without its own power, the limited in-feed of the roll<br />
preserves the condition of the rolls, as well as the bearing and<br />
the line itself. This creates a lifespan <strong>for</strong> the rolls averaging<br />
four to five years (depending on individual application) with<br />
only minimal maintenance. All that is needed is trimming<br />
operation and follow-up grinding of the roll surface from time<br />
to time.<br />
As the example below shows a typical strip cleaning line<br />
through the use of NOVOTEX ® non-woven rolls in the third<br />
and fourth exchange of the squeezing roller pair, it would be<br />
possible to dispense with the hot-air drying facility entirely in<br />
favour of a vacuum squeezing system.<br />
Squeezing rolls<br />
Vacuum squeezing system<br />
can replace hot air drying<br />
NOVOTEX ®<br />
Another important advantage is that this system innovation is<br />
extremely simple to implement into existing strip lines. Only<br />
the last pair of squeezing rolls in the plant has to be exchange<br />
out. At the same time, the external dimensions of the rolls<br />
normally remain unchanged and the existing bearings can be<br />
used. Even when additionally installed into an existing strip<br />
line, the space requirement <strong>for</strong> a complete unit with a frame<br />
construction is less than one metre width. The vacuum unit<br />
itself also requires very little space and does not have to be<br />
placed directly on the pair of rolls.<br />

<strong>Innovative</strong> equipment technology<br />
Brushing equipment <strong>for</strong> strip processing lines<br />
By linking our technological leadership in brush rollers with<br />
the competence and experience gained from teaming up with<br />
a wide range of line installers across the world, we are, in<br />
cooperation with selected partners, in the position to offer<br />
well-engineered and individually adapted brushing machines<br />
and line concepts, which go further than the established standard<br />
machinery. Our focus primarily lies in replacing old<br />
equipment, which no longer works optimally in existing lines,<br />
while at the same time optimising brush rollers and usage<br />
parameters in order to achieve sustainable quality and<br />
process improvements.<br />
New intelligent concepts <strong>for</strong> brushing machines<br />
Along with this background, we are also able to offer a new, fully<br />
patented machine package which includes a variety of innovative<br />
developments:<br />
• A rigid machine housing which is heavily cushioned against<br />
vibrations and protected against corrosion made of a composite<br />
stainless steel/mineral cast construction<br />
• Compact and extremely dense OSBORN HDL ® brush rollers enable<br />
precise control of the depth of immersion<br />
• Easy and quicker replacement of the rollers within a few minutes<br />
using an insertion skid with no additional dismantling tools<br />
• Compact design enabling the unit to require little space - only<br />
1500 mm <strong>for</strong> each upper/lower brush <strong>for</strong> strip widths up of to approx.<br />
2000 mm<br />
• Easy and precise positioning of the rollers through mechanical<br />
clamping<br />
• Optimum and reliable feeding of the brush rollers via the immersion<br />
depth by means of height adjustment using precision lifting spindle<br />
elements with a servo positioning motor (parallelism tolerance<br />
approx. 0.1 mm)<br />
• Replacement of the rollers without disassembling the bearing units<br />
• Optical control at any time through side access doors with large windows<br />
on the operator side and the interior lighting of the plant<br />
• Non-contact measurement of the roller diameter in operation<br />
• Optional construction according to the brush/brush principle<br />

For many years, Japanese lines have maintained a leading<br />
role in technology. In recent years, we have been able to successfully<br />
combine new line projects with renowned steel producers<br />
in Europe, North America, Asia and Africa together<br />
with our Japanese partners by adjusting the components to<br />
international standards.<br />
• With these lines, the brush/brush principle instead of the<br />
conventional brush/back-up roll design provides a number<br />
of advantages.<br />
• Due to the reduction of required roll pairs by half, a 50%<br />
space saving is achieved.<br />
• In the case of thin straps, the brush in the border area no<br />
longer works on the back-up roll but combs in the opposite<br />
brush. Fully uni<strong>for</strong>m wear of the brush balling is achieved in<br />
the border area through the additional oscillation of the<br />
rolls.<br />
• In all, the per<strong>for</strong>mance of the respective strip cleaning unit<br />
is significantly improved. As a result, strip quality and line<br />
speed can be increased.<br />
• Acquisition and maintenance costs are correspondingly<br />
reduced.<br />
• Above all, when exchanging brush machines in existing strip<br />
lines, valuable space <strong>for</strong> additional pre-cleaning sections<br />
can be achieved in addition to more intensive brushing.<br />
• The contact surfaces strip/upper brush and strip/lower brush<br />
are identical. This reduces vibrations. Through gentler running<br />
of the strip, shading and shatter marks on the<br />
strip surface are avoided.<br />

Shafts <strong>for</strong> Yoke Style Idler-Rollers<br />
Load Runners ® idler rolls are tightly sealed and greased <strong>for</strong><br />
their entire service life. As such they are insensitive to dirt,<br />
moisture and extreme temperatures. Long-life and maintenance-free<br />
operation ensures high levels of economy.<br />
The treads are made of high-strength steel and are then surface<br />
hardened to 55-60 HRC. As such, they feature an especially<br />
wear-resistant surface with a tough core.<br />
The precision tapered roll bearings and grooved ball bearings<br />
used are particularly suitable <strong>for</strong> both radial and axial loads<br />
and can even be used at high speeds. This secures key advantages<br />
over conventional needle bearings.<br />
Precision adjusted and hardened guiding rails made of highduty<br />
alloy steel are extremely resilient, wear resistant and<br />
free from twist effects. As such, heavy loads can be moved<br />
precisely and reliably.<br />

An optimal brush result is determined by different parameters.<br />
After selecting the appropriate bristle, brush design,<br />
fill density and trim length in the process, we focus on the<br />
correct operational parameters.<br />
Criteria such as surface speed, brush speed, depth of<br />
immersion and contact pressure have to be taken into<br />
account and individually defined under the given framework.<br />

Different applications and fill materials require different<br />
speeds, and the appropriate speed depends on the roll<br />
diameter.<br />
The optimum contact pressure can vary greatly as well and<br />
depends on the brush construction and the fill density. The<br />
decisive factor in achieving the required brush result is the<br />
immersion depth, as a brush tool works primarily with the<br />
bristles and/or the tips of the wire.<br />

Optimal brush per<strong>for</strong>mance is achieved through the use of<br />
compact brushes and high quality fill materials.<br />
Consequently, cooling plays a crucial role, as overheating<br />
can quickly lead to the bristles becoming brittle causing<br />
premature breakage. The brush cooling facility in the plant<br />
/ line is optimised by correcting and adjusting the angle of<br />
spray and flow rate. In turn, this significantly extends the<br />
lifespan of the rollers. The selection of the correct spray jets<br />
also plays an important role.<br />
