ABSTRACT:
An improved support structure for an upper press member that broadens the bending capabilities of a conventional press bending apparatus. The support structure is carried on the upper platen frame of the bending apparatus and is adapted for providing reciprocating movement between the upper press member and the upper platen frame. The support structure comprises a base plate which is attached to the platen frame and a subplate which is adapted for supporting the upper press member. Fluid activated cylinders are mounted on the base plate, with the free end of their piston rods affixed in a supporting manner to the subplate whereby actuation of the cylinders will provide relative movement between the subplate and base plate and therefor the upper press member and the platen frame.
