For analysing paper and print test samples,<br />
<strong>Voith</strong> uses the latest measuring<br />
technology and laboratory facilities in<br />
teamwork with renowned printing firms.<br />
To meet such high demands, <strong>Voith</strong> <strong>Paper</strong><br />
uses highly sophisticated instrumentation,<br />
mobile in part, incorporating the latest<br />
technical advances.<br />
Typical example 1<br />
Fig. 4 shows how the operating stability<br />
and production output of a modern highspeed<br />
newsprint machine were improved<br />
after replacing a faulty pressure transducer.<br />
After eliminating the source of trouble,<br />
breaks decreased dramatically. And in<br />
parallel to these savings in down-time,<br />
the 1,600 m/min speed limit was perma-<br />

was thus attained. (It is apparent that<br />
quality benefited also.)<br />
In the end, the key to such success lies<br />
in the experience and a systematic and<br />
analytical approach of the <strong>Voith</strong> <strong>Paper</strong><br />
on-site optimization team. We’ll be<br />
pleased to tell you more about how this<br />
concept can benefit your mill too.<br />
