Class Information
Number: 72/389.3
Name: Metal deforming > By relatively movable offset tool-faces (e.g., for bending or drawing) > With tool motion in fixed path > Between and co-planar with opposed tools > For a small radius bend > Elongated knife edge die (i.e., press brake)
Description: Device wherein the single tool face is comprised of an elongated ridge parallel to the plane of the contraposed tool-faces, such that, as measured along the ridge the members are much much longer than wide and cooperate to create a sharp straight bend in a planar or sheet-like workpiece.
