Abstract
Pressing apparatus wherein a cell containing a workpiece is subjected to pressure in a press in which at least one resilient layer of disc-spring units is used as a pressure distributing medium comprises a press, two press plates and a pressure distributor disposed between the pair of plates and one of the press platens. The pressure distributor consists of a plurality of disc-spring units disposed adjacent to one another over the surface of a supporting plate. Each disc-spring unit comprises a pair of disc-springs disposed one on either side of the supporting plate with the apexes of the springs towards each other, the springs of each pair being fastened together by means of rivets passing through an orifice in the plate.
