Abstract: Each of the ends of an elongated plate-formed attachment member, to which is attached a diaphragm and a press pad, is connected to a transportation unit which allow for the plate-formed attachment member to be moved into and out of a press stand along suitably provided tracks. The transportation units include bogies and connection units mounted on the bogies which support the plate-formed attachment member. The connection units include bearings so that the plate-formed attachment member can be rotated when positioned outside of the press stand, and at least one of the connection units include lifting cylinders to raise and lower the plate-formed attachment member as appropriate.

Abstract: In a hydraulic press which includes a pressure cell with a diaphragm of flexible material which is intended to press a pad of flexible material against forming pieces in a working space below the pad, the diaphragm has an opening with an annular bead therearound. Two disc-like attachment members are provided, which form between them an annular groove which fits the bead of the diaphragm. Between the bead and one of the attachment members there is formed an annular groove within which is a sealing ring which engages between the bead and at least one of the annular members.
