A press for molding large sheets around a forming surface which includes an elastic press pad, a first frame member on the side of the press pad away from the working surface thereof, the first frame member having a top wall and side walls forming a pressure cell area therebetween, an elastic diaphragm in the pressure cell area in contact with the press pad, a second frame member formed in a generally L-shaped configuration to encompass and hold an annular bead of the elastic diaphragm, a trough-shaped supporting member positioned adjacent the end walls of the first frame member and the press pad such that a gap is formed between the end walls and the supporting member, a movable seal strip positioned in the gap to prevent the press pad from being pressed out of the pressure cell area when the elastic diaphragm is expanded, and a supporting strip attached to the end walls of the first frame member at a point within the pressure cell area to secure the press pad within the pressure cell area. |
