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.
