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.
