Polyurethane Press Roll Covers Boost Dryness after First Press

Radece papir, Slovenia, reports that it was able to increase dryness after the first press of its PM 4 by 0.8%, operating with Voith (Germany) polyurethane covers. Special surface designs of the polyurethane covers made the improvement possible, according to the mill.

A press analysis with Voith measurement equipment provided the necessary data. Based on the results, a water balance analysis was carried out and the optimum surface design for this application was calculated. The surface configurations of the Voith polyurethane covers are highly flexible and allow an individual adjustment to the customer's needs.

"Deployment of the polyurethane cover was a complete success. We are very happy with the 0.8% dryness gain after the first press on PM 4. The Voith covers are a worthwhile investment," said Ales Knavs, production technologist with Radece Papir.
