Abstract

A long nip press for machines transporting fibre webs, which press drains water from the fibre web and comprises two hydrostatic bearings opposite each other, both comprising a pressure shoe comprising a pressure chamber, the pressure shoe having a sealing element in the form of a flexible pressure-balancing diaphragm, and a press belt to press the fibre web against a fabric, the pressure-balancing diaphragm protruding on its edge-zone without support from the inner rim of the pressure shoe towards the pressure chamber. So as to make the long nip press very simple in structure and to enable self-adjusting, even and efficient lubrication in the nip, the protruding edge-zones comprise pinholes for transporting hydraulic fluid. The invention also relates to a pressure-balancing diaphragm.
