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.
