1. A method of exchanging a diaphragm in a press of pressure cell type which includes a force-absorbing press body and encloses a press chamber, the diaphragm is made of a resilient material, and is adapted to be arranged to rest against a diaphragm support in the press chamber, the diaphragm forming together with a press plate, a pressure cell adapted to exert a forming pressure on a workpiece, the method comprising:
exposing the diaphragm support inside the press chamber in any direction;
removing the diaphragm support with the diaphragm loosely resting therein from the press chamber during which the diaphragm support encloses the diaphragm and extends around the entire periphery thereof;
inserting a unit, which comprises a second diaphragm loosely resting within said diaphragm support or a second diaphragm support, into the press chamber; and
arranging the unit at its intended location.
