Abstract

A press of pressure cell type comprises a press stand with two opposing force-absorbing elements between which a space is formed. In this space there is located a plate with a recess in which an elastic diaphragm is arranged. The diaphragm forms, together with the plate, a pressure cell. Elongated side supports for the diaphragm are provided at the sides of the said space. A tray insertable into the space forms, together with the plate and the diaphragm, a closed press space. The pressure cell is connected to a pressure medium source. Each side support is formed with an elongated recess, in which there is arranged an expansible membr of elastic material. Each expansible member forms a side support for a press tool located in the tray.
