ABSTRACT:
A device for separating the platens of a press so that wooden blanks in an unpressed form can be readily loaded therebetween. The device includes outwardly extending arms carried on the corners of each of the platens. Pneumatically operated bellows are provided between cooperating pairs of outwardly extending arms which are carried on diagonally opposite corners of each of the platens for separating the platens when pressurized. Alternate pairs of platens have pairs of bellows interposed between the outwardly extending arms carried on different diagonals. A switch is carried below the press for disengaging the pneumatic system when the press is being closed.
