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.
Apparatus for forming an extended nip between a mating roll and a shoe roll for treating a material web, the shoe roll having a carrier and a flexible roll shell rotatable about the carrier, which roll shell is supported in the region of the extended nip on a head face of a press shoe which is guided on the carrier, and the press shoe for generating a pressure is movably supported on the carrier using a fluid-load pressure chamber, the pressure chamber being configured as a pressure cushion on which the press shoe by way of the rear side is supported in a planar manner, wherein the pressure cushion is placed in a groove-type chamber, wherein the press shoe on the rear side has a male form portion, which projects into a pressure cushion which can be sunk, and the pressure cushion to this end is supported in a guiding manner by way of a pressure-cushion side wall, which forms a rollable wall, on the groove-type chamber.
