Abstract
A press comprising a press stand, a pressure cell arranged in the press stand with an elastic diaphragm and a tray-shaped tool-carrying member, insertable into the press, in which a forming tool and a workpiece are located. In the inserted position of the tool-carrying member in the press, a closed working space is formed between the pressure cell and the tool-carrying member. The diaphragm is placed in a recess in a press plate. The seal between the diaphragm and the press plate consists of a U-shaped sealing ring having flanges directed inwards towards the center of the pressure cell.
