<strong>Nagel</strong> creasing machines<br />
Professional creasing before folding<br />
Digitally printed sheets are very sensitive <strong>and</strong> must be<br />
h<strong>and</strong>led gently during finishing. To prevent a deterioration<br />
of the quality <strong>and</strong> appearance of the product, the<br />
sheets must be creased before they are folded.<br />
During creasing, the stock is gently compressed<br />
to prevent cracking or toner breaking. <strong>Nagel</strong><br />
creasers ensure accurate creasing for<br />
an optimum folding result in the next<br />
finishing step.<br />
Intuitive operation of Pro machines<br />
The new touch screen panel of the Pro generation is<br />
essentially larger than the previous panel. All major<br />
functions get operated via this panel. Only the sheet<br />
length <strong>and</strong> the fold type for the finished product have<br />
to be keyed in (popular sizes <strong>and</strong> folds are pre-set). The<br />
software will automatically calculate where the creases<br />
need to be <strong>and</strong> set them accordingly. Any minor changes<br />
to the crease position can be made by touching in the<br />
relevant section. <strong>Folding</strong> gap data are displayed digitally<br />
on the panel.<br />
Another advantage is the language-independence of<br />
the software – only symbols are used, what makes<br />
translations unnecessary. Learning to operate the new<br />
touch screen is very easy.<br />
PosiFeed<br />
<strong>Nagel</strong> creasing machines are the ideal choice for sophisticated<br />
finishing of very different stocks – paper, cardboard<br />
or booklet covers, varnished, laminated, mattcoated or with<br />
the wrong running direction. All models are very easy to use.<br />
All <strong>Nagel</strong> creasers – AutoRillnak 50,<br />
AutoRillnak 33 <strong>and</strong> DigiRillnak – use the<br />
optimised knife-against-groove creasing<br />
process. Unlike in rotary creasing,<br />
a polished creasing knife presses the<br />
paper into a solid creasing matrix<br />
without stretching the paper fibres.<br />
With this technology, paper of up to<br />
350 gsm can be creased effortlessly.<br />
The extensive alpha-numeric memory allows an unlimited<br />
number of jobs to be stored <strong>and</strong> named as chosen.<br />
All machines, as well as the AutoRillnak 33, are equipped with a new feeder (= PosiFeed). The feeder stops the drum<br />
as the vacuum pulls the sheet down before the drum starts to feed. This significant change enables the feeder to be<br />
piled higher <strong>and</strong> feed more difficult stocks.
