A filter press including a plurality of filter plates, a pair of filter cloths disposed at opposite faces of each of the filter plates, a wind-up device for winding up the pair of the filter cloths, a guide member having a pair of curved guide surfaces formed at its opposite side edges, respectively and a pair of guide rollers. The pair of the filter cloths are guided downwardly by the guide member and the pair of the guide rollers so as to be wound up by the wind-up device such that the pair of the filter cloths are bent inwardly toward each other at the pair of the curved guide surfaces of the guide member, respectively.

Filter press

A filter press having a plurality of filter plates so supported between fixed and movable heads of the machine framework that the filter plates can selectively be separated from each other and compressed together to a substantially watertight closure between the fixed and movable heads. A filter medium is provided for each filter plate and is composed of a pair of filter webs covering respectively the opposed filtering surfaces of the filter plate. The filter webs are connected at their one end to a winding device and at their other end to a tensioning and winding roll assembly after having turned around a pair of juxtaposed guide rolls. Each tensioning and winding roll assembly is composed of a cylindrical roll and a biasing element for biasing the cylindrical roll in one direction with the filter webs forced to be wound therearound.
