manner. The success and the highlights<br />
mentioned here are a consequence of this<br />
symbiosis.<br />
During the first meetings it already<br />
became clear that the communication<br />
between the customer, supplier and local<br />
engineering contractor worked excellently.<br />
Based on a jointly optimized delivery<br />
schedule, it was possible to start erection<br />
three weeks earlier than planned. The<br />
erection work, carried out by the customer<br />
and supervised by <strong>Voith</strong> personnel,<br />
was very soon far ahead of schedule.It<br />
was, therefore, possible to complete erection<br />
at the construction site eight weeks<br />
ahead of the scheduled date, managed<br />
excellently by the customer.<br />
The startup process already promised to<br />
be record-breaking: after starting at 80%<br />
of max. operating speed, it was possible<br />
<strong>17</strong>/04<br />
to produce cigarette paper of high quality<br />
at 100% max. operating speed after only<br />
eight weeks. Only 5 months after startup,<br />
Mudanjiang Henfeng <strong>Paper</strong> produced<br />
high-porosity cigarette paper on its PM 12<br />
at a speed that is 15% above its layout.<br />
On the one hand, this is due to the technological<br />
competence of the customer<br />
and its highly qualified personnel, and<br />
on the other hand it is due to the proven<br />
and at the same time innovative machine<br />
concept.<br />
The machine concept<br />
On two lines for long and short-fiber<br />
pulp, the customer is able to make use of<br />
the advantages of the TwinFlo refiners in<br />
an excellent way: in order to maintain<br />
porosity within the narrow limits required,<br />
a freeness value that can be exactly<br />
adjusted and, above all, is constant<br />
over time is of fundamental importance.<br />
A highly efficient cleaner plant, operating<br />
according to the EcoMizer concept, as<br />
well as the MultiScreen pressure screen,<br />
especially designed for low-pulsation and<br />
uniform stock throughput ahead of the<br />
headbox, ensure a very good uniformity<br />
of the stock suspension ahead of the<br />
headbox and in the machine direction paper<br />
profile. The use of ComMix for stock<br />
component mixing and HydroMix for the<br />
necessary stock dilution additionally reduces<br />
the stock volume in the system<br />
and, therefore, allows fast grade changes.<br />
A RollJet K headbox ensures uniform distribution<br />
of the stock across the machine<br />
width. Just as the freeness and the<br />
aproach flow system are important for<br />
uniformity in machine direction, the<br />
headbox is the decisive link for uniformity<br />
in cross direction. Hardly any other<br />
supplier beside <strong>Voith</strong> can offer a product<br />
in this area that is as mature and perfected.<br />
This headbox is still being developed<br />
