| 发明名称 | Device and method for producing a material web | ||
| 摘要 | 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. | ||

| 主权项 | 1. A device for dewatering a fibrous web, comprising: a suction equipped mating element having a curved surface; and a permeable press belt having a running side and a contact side making direct contact with a second side of the fibrous web and having a texture adapted to a quality of the fibrous web which is to be produced, said permeable press belt and said suction equipped mating element defining a press zone therebetween, said permeable press belt wrapping at least partially around said curved surface and being configured such that a tensile stress of at least 20 kN/m can be applied to said permeable press belt to produce a pressing pressure in said press zone, said permeable press belt comprising at least a first woven fabric layer; and a permeable carrier belt arranged between said suction equipped mating element and the fibrous web with a first side of the fibrous web lying on said permeable carrier belt, said permeable carrier belt guiding the fibrous web through said press zone and said permeable press belt, the fibrous web, and said permeable carrier belt configured to allow a fluid to flow therethrough in at least a partial region of said press zone. | ||
