Press membrane from a rubber-elastic material

The invention relates to a press membrane for a filter plate of a filter press. Said press membrane consists of a rubber-elastic material and is supported by the filter plate while supporting a parallel filter cloth. An intermediate chamber defined between the press membrane and the filter plate can be impinged upon with a pressure medium. The aim of the invention is to prevent an overload of the membrane material in the area of the supporting cams and damages of the filter cloth in said areas. To this end, the press membrane is provided with transmission disks in the area of the supporting cams, said transmission disks consisting of a substantially harder material than the rubber-elastic material of the remaining press membrane and being vulcanized into the rubber-elastic material.
