ABSTRACT:
This disclosure includes entry and delivery clamps arranged on opposite sides of a multiplaten press for clamping belting in order to apply a tension to the belting prior to pressing. The tension is applied by moving the entry clamp in a direction away from the press. The belting is fed over support rollers on opposite sides of the press which receive the belting from different openings of the press. These rollers are caused to move before the press is closed to maintain the belting away from the hot platens of the press, then moved in concert with and in the direction of the platens during pressing and then, if required, they may be moved independent of the platens when the press has been opened after pressing to effect a stripping of the belting from the platens.
