ABSTRACT:
An extended nip press for a paper machine for removing water from a fiber web carried by a porous felt through a press zone in which the web is subjected to a pressure action. The press comprises press rolls forming at least two separate press nips and a sealing element positioned between the second rolls forming the press nips. The web, the felt and a band supporting the web and felt is passed through the press nips. A pressure medium chamber is limited by that part of the band which extends between the press nips, by the secondary rolls and the sealing element for subjecting the web to the pressure action. The press nips form rolling seals between the secondary rolls and the band.
