Abstract
The invention relates to an extended-nip roll press for dewatering a fibrous web in a press nip which, on one side, is formed by a rotating mating roll and, on the other side, is formed by an extended-nip press roll, whose roll centers lie in a stack plane, and the extended-nip press roll has a stationary support and a flexible roll cover that can rotate about the support, the cover in the region of the press nip being supported on the support on a sliding surface which is formed on an upper part, defining an entry and exit, of a press shoe that can be displaced with respect to the support in a loading direction, it being possible for the press shoe to be displaced radially along a loading plane which intersects the stack plane at the center of the mating roll and at an acute angle to the exit direction.
