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.

摘要： A paper machine having a forming fabric with a paper side plurality of weft and warp yarns interwoven to form a layer contacting a paper web. A plurality of weft and warp yarns are interwoven to form a machine side layer for the forming fabric. A plurality of warp binder yarns are interlaced with the paper side and machine side yarns to form a multiple layered forming fabric. The weft yarns in the machine side layer are greater in diameter than the warp yarns for maintaining width stability of the fabric. The fabric is characterized by high permeability, high void volume and a high Beran's Fiber Support Index.
