Abstract: A filter press comprises a support plate and a pressure plate and a set of chamber-type filter plates arranged therebetween. Each filter plate is provided with a cloth filtering barrier in the form of an endless belt which is supported by two rollers fastened to two opposite walls of the filter plate in such a manner that both runs of the belt extend on the side of a draining barrier of the filter plate. There are provided two bars for displacement of the filtering barriers extending along the set of the filter plates on opposite sides of the set, the bars having a drive for their concurrent transverse reciprocation, and there are also provided rods which are fixed to each endless belt to extend transversally thereof and movable along and together with the bars in transverse direction relative to the set of the filter plates.
