  • Patent number: 8728277
    Abstract: A method to dewater a fibrous web includes directing the fibrous web through a first press zone defined between a revolving permeable belt and a revolving permeable support belt and having a first press zone length. The fibrous web is arranged lying between the revolving permeable belt and the revolving permeable support belt. A fluid is caused to flow through the permeable belt, the fibrous web and the support belt at least over a section of the first press zone length. The fibrous web is dewatered in a second press zone following the first press zone and defined between the revolving permeable belt and the revolving permeable support belt, the second press zone having a second press zone length. The fibrous web is led through the second press zone between the permeable belt and the support belt, the permeable belt and the support belt each having a different compressibility.

  • Patent number: 8382956
    Abstract: A device for drainage of a pulp web, particularly a tissue web, having a first pressing zone having a first pressing zone length through which the pulp web is fed horizontally between a circulating, permeable band and a circulating, permeable support band. The first pressing zone is designed such that a fluid can flow through the band, the pulp web and the support band at least on one part of the first pressing zone length. In addition, the device has a subsequent second pressing zone having a second pressing zone length. The pulp web is guided through the second pressing zone between two bands having differing compressibility.
