ABSTRACT:
The disclosure concerns a press device for a paper making machine, and particularly concerns an extended nip press. A hollow tubular, stationary support body extends around a supporting beam, which is a flexing beam. Hydraulic piston-cylinder combinations extend between the beam and the supporting body in a press plane. A radially non-displaceable press shoe is supported on the support body and faces toward a counter-roll to define a press nip between them. The outwardly facing surface of the press shoe is concave in the circumferential direction of the support body. The amount of pressure in the hydraulic supporting means determines the press force which prevails in the press zone.
