ABSTRACT:
A movable guide gauge for accurately locating an edge of a preformed sheet placed on a lower die of an edge bending press is fixed to a cam follower slidably mounted on a sublifter and spring-loaded toward a retracted position away from a bending edge of the lower die. A cam mounted above the cam follower alongside an upper die has a slanted surface corresponding to the slanted surface of the cam follower, the slanted surfaces being designed so that they are brought into abutting slidable engagement with each other to move the guide gauge from the retracted position to a predetermined position for guiding the edge of the workpiece as the cam moves downward with the upper die.
