Abstract
An extended nip press for dewatering a pulp web has two press rolls that form an extended nip. The first press roll is retained in the axial direction at least at one end, and is held with its bearing pins on first bearing blocks. The second press roll is also held with its bearing pins on second bearing blocks. The second bearing blocks can be tensioned, each in pairs, with respect to the first bearing blocks by flexurally elastic tension elements, the tension elements allowing a relative displacement of the press rolls in the axial direction. The second bearing blocks are fixed in position with respect to the first bearing blocks in order to prevent excessive bending stress on the tension elements. For this purpose, either the rotary bearings of the second press roll are configured in non-tilting fashion, or additional support bearings are provided.
