Abstract: The invention relates to a device for dewatering a fibrous web with a press zone which is formed by a mating element with a curved surface and a permeable press belt which wraps at least partially around the curved surface and has a running side and a contact side contacting a second side of the fibrous web. A permeable carrier belt arranged between the mating element and the fibrous web guides the fibrous web through the press zone. The device is configured so a fluid can flow through the press belt, the fibrous web, and the permeable carrier belt at least in a part region of the press zone. The permeable press belt is configured to generate a pressing pressure in the press zone when a tensile stress of at least 20 kN/m is applied and the contact side is adapted to a quality of the fibrous web produced.

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.
