Automation<br />
On the basis of a uniform and constant<br />
operating and engineering interface for<br />
the machine controls, the process and<br />
quality control system, <strong>Voith</strong> <strong>Paper</strong><br />
Automation supplied the entire automation<br />
for the Maxau PM 6 production line.<br />
The OnQ quality control technology is<br />
matched to the production process in<br />
such a way that short control loops and<br />
thus fast response times on changes in<br />
the quality parameters are possible. Besides<br />
the OnQ quality measuring frames,<br />
numerous CD and MD controls are used<br />
in production. Thus an SC paper is produced<br />
on PM 6 that is perfectly suited<br />
to further processing in the rotogravure<br />
printing process.<br />
The automation concept is completed by<br />
the OnView Information System with machine<br />
and process status monitoring as<br />
well as a sheet break analysis and sheet<br />
inspection system. With this, all product,<br />
process and machine data can be collected,<br />
analyzed and prepared. In addition,<br />
the VariTop winder has been completely<br />

the new generation.<br />
The result<br />
On September 15, <strong>Voith</strong> <strong>Paper</strong> again proved<br />
with the production of the first paper roll<br />
on the new PM 6 their professionalism in<br />
the processing of such complex projects.<br />
The first printing tests turned out to be<br />
positive and allow us to expect an optimal<br />
conclusion to the project.<br />
The production line of PM 6 includes the<br />
following modules of the One Platform<br />
Concept:<br />
● ModuleJet headbox<br />
● DuoFormer TQv<br />
● DuoCentri-NipcoFlex press with 4th press<br />
● TopDuoRun dryer section<br />
● Janus calender<br />
● Sirius reel<br />
● VariTop winder (rebuild)<br />
● Complete engineering for PM and<br />
peripherals as well as almost complete<br />
delivery<br />
● Complete engineering and delivery of<br />
the electrical control and power section<br />
● Increasing the capacity of the DIP<br />
stock production, including disc filter<br />
rebuild work.<br />
Stock preparation<br />
As deinked recovered paper is also used<br />
as the main furnish besides bleached<br />
groundwood and chemical pulp, the<br />
capacity of the existing recovered paper<br />
preparation system also had to be<br />
expanded because of the significant increase<br />
in the paper machine capacity.<br />
The production rates have been continually<br />
raised over the past few years and all<br />
three DIP systems have been operating<br />
significantly beyond their original layout<br />
specifications. The additional capacity<br />
increase by about 20%, spread over two<br />
DIP lines, therefore presented a great<br />
challenge.<br />
First, a detailed project study and balance<br />
of the actual condition of the two selected<br />
DIP lines 1 and 3 were carried out.<br />
