Strato Series –<br />
rubber covers in the paper machine<br />
Roll covers in the paper machine can have a major impact<br />
on the quality characteristics of the finished paper. At <strong>Voith</strong> <strong>Paper</strong><br />
we engineer our roll covers to meet the demanding requirements of<br />
the paper maker. These requirements are both for excellent paper<br />
quality and predictable, extended run cycles.<br />
Rubber covers are widely used in many<br />
different functions in a paper machine<br />
from wire rolls to reel drum covers. Each<br />
position has different quality requirements<br />
for the roll cover. When selecting<br />
the correct roll cover, we must consider<br />
the specific application and the requirements<br />
of that application. However, each<br />
application has one common requirementabrasion<br />
resistance.<br />
In the press section of a paper machine<br />
the roll cover needs to provide consis-<br />
45<br />
tent, efficient dewatering capabilities and<br />
provide excellent sheet release for low<br />
draw and improved operating efficiencies.<br />
In the sizing and coating section the<br />
roll cover plays an even more important<br />
role in the surface characteristics of the<br />
paper. The correct roll cover must provide<br />
a homogeneous surface for the application<br />
of sizing or coating, reduce or<br />
even eliminate sheet stealing and misting<br />
while providing the correct nip conditions<br />
to optimize sizing and coating application.<br />
In both the press and sizing/coating<br />
