New Press Fabric for Board and Packaging Paper: Revolution Dewaters at an Unsurpassed Level

摘要

Revolution, available as an endless or a seam fabric, was designed specifically for producing board and packaging paper. The newly developed press fabric technology allows polymers to be integrated into different levels of the fabric structure. Revolution can thus maintain a uniform pore volume even under a high load. The structural stability of the fabric is ensured at all times. When the fabric is compressed, the water drains far more easily through the fabric structure. The felt is saturated more quickly, and the hydraulic pressure aimed for in the nip is reached at an earlier stage. Revolution thus controls the de-watering before, during and after the nip. Revolution can increases the dry content as compared to a conventional fabric by up to 2 per cent.
