Get the best dewatering performance for your graphic paper machine

With QualiFlex CrestW and QualiFlex CrownW, Voith provides two superior press sleeves targeting best total performance for graphic paper machines.

The sleeve is a key component of the press section. It has to be flexible to follow the deformation and bending when going through the press nip at high speeds up to 2,000 m/min and beyond. It is expected to be stable to withstand high pressures and provide maximum void volume at high loads, as well as be resistant both to mechanical and chemical wear. These attributes result in long-time, superior dewatering performance.

To reach optimum dewatering and best paper quality, grooved surfaces are the dominating choice for high-speed machines. With QualiFlex CrestW and QualiFlex CrownW, a large variety of surfaces is available. Groove shape, open area and void volume can be designed exactly to your needs.
