Abstract
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.
