ABSTRACT:
A compensating bolster and die holder combination for use with the bed of a press brake to provide vertical adjustment and compensating camber to the die holder supported thereby. The die holder is vertically moveable in an open channel of an underlying elongated bolster fitted to the bed of the press; with plural wedge members, moveable transversely of the die holder, serving to adjustably position and support the latter. Each wedge member has joined thereto an indicator pin extending through one side of the bolster which operates to visually indicate the adjusted position of its wedge member; while the several indicator pins cooperate to show the relative adjusted positions of the several wedge members and the consequential adjusted elevation of the die and die holder.
