ABSTRACT:
A multi-piece die section for a press brake installed rotary bending tool in which a forming anvil is positioned in a holder in accordance with the thickness of material to be bent so that the rotary bender and press brake operate on the same center line. In one version of the holder a forming anvil is adjustably positioned relative to the center line of the rotary bender and in a second version thereof the forming anvil is precision sized in accordance with the thickness of the work material whereby to eliminate the need for shims and readjustment of press ram stroke as required by the first version.
