Abstract: A ram-type press expresses liquid from material being pressed, particularly from a batch of wet textile materials. A press ram can be moved onto the material being pressed by the action of a pressure cylinder. A cylindrical shell, accommodating the material being pressed, can be closed at its bottom by a perforated thrust plate. The materials to be pressed and the press ram can be introduced one after the other from above into the cylindrical shell. The press ram is connected to an edge of an opening of a pot-shaped elastically yielding cushioning member and includes a union which can be connected to a water main in order to introduce water into the cushioning member. The bottom of this cushioning member forms a membrane which can be pressed against the material from which the liquid is to be expressed.

Abstract: Disclosed is a water-removal press having, in a machine framework, a press base with discharge openings, a circular-cylindrical filling frame with end faces open on both sides, and a press piston. The filling frame and the press piston are displaceably guided perpendicularly on common guides and are vertically adjustable in each case by means of a lifting device. The press piston has a rigid piston body and a pot-shaped diaphragm enveloping the piston body from below. In the non-operating position, the outside diameter of the press piston is smaller than the clearance width of the filling frame. During the press operation, the press piston plunges into the filling frame. When a pressure fluid is applied to the inner side of the pot-shaped diaphragm, the latter sits against the periphery on the filling frame and expands at the end face down to the washing mass located below it to press out the latter.

A diaphragm is mounted on the cover. A pressure medium can be introduced in the space between cover and diaphragm. The water pressed out of the laundry is collected and discharged from a vessel. The cover and the pressing basket are displaceable independently from one another. The pressure medium is introduced initially by means of a quickly delivering pump and the actual pressure for pressing out the laundry is provided by a piston pump.

Abstract: A device for extracting water from a load of articles which have been washed uses fluid pressure to exert a force on the load. A system controls the fluid pressure such that only low pressure is applied to the load for a predetermined period of time at the beginning of the water extracting operation. Subsequently, the load is subjected to a high pressure exerted by the fluid.

Abstract: The press container of a wash press sits on a porous press plate. Because of the high press pressure of the press piston head the fabrics of the wash are partially forced into the holes of the press plate. In order to remove the pressed wash safely from the press plate, the pressed wash is raised somewhat from the press plate when the press container and press piston are simultaneously raised, first into a middle position in which the press piston head remains, while the press container is raised further. The wash loosened in this way can be safely slid laterally from the press plate.
