Abstract
A press for extracting water from wet washing comprises a housing, a perforated press floor for supporting a batch of wet washing, and a hydraulic ram for pressing the wet washing down against the press floor. The hydraulic ram is constituted by a generally bell-shaped diaphragm carrier whose open end is closed by a bowed-in, flexible diaphragm. The hollow interior of the diaphragm carrier is pressurizable with hydraulic fluid. A charging frame is provided to assist with the uniform pressing of wet washing while helping prevent damage to the washing arising from jamming. The charging frame is movable with the diaphragm carrier towards the press floor.
