A method for treating a pulp web in a paper or tissue machine with an extended-nip press unit. This extended-nip press unit includes a shoe press roll with a revolving press belt and a backing roll, where the pulp web is dewatered in the extended press nip between the backing roll and the press belt and where the pulp web is carried on the revolving press belt of the press roll after the extended press nip to a transfer fabric that receives the pulp web. The transfer fabric is guided over a stationary transfer device in the transfer area. A corresponding device for treating the pulp web.

Method and device for treating a fibrous material web in a long nip pressing unit

Disclosed is a device for forming an extended nip between a counter roll and a shoe roll for machining a material web, wherein the shoe roll has a support and a flexible roll shell, which can rotate around the support () and which rests in the region of the extended nip upon a head surface of a press shoe guided on the support, and the press shoe displaceably rests on the support in order to generate a press pressure via a pressure chamber to which fluid can be applied, the pressure chamber is disposed as a pressure pad, on which the press shoe rests surficially on the rear side, wherein the pressure pad is inserted into a groove-like chamber, wherein the press shoe has a stamp-like section on the rear side, which stamp-like section descends into an invaginable pressure pad in order to perform reciprocating movements, and the pressure pad is guidedly supported on the groove-like chamber along a pressure pad lateral wall that forms a roll wall.
