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.
