ABSTRACT:
An automatic bending apparatus for forming fasteners from metal wire strip, or bar stock includes a removable, axially movable, non-rotatable shaped central mandrel and a relatively rotatable faceplate mounting a bending pin disposed coaxially with the mandrel and independently axially movable relatively thereto. The apparatus includes a pair of shears positioned adjacent the mandrel along the path of movement of the stock and in advance of the mandrel and means for automatically feeding the stock. The invention is characterized in that the mandrel is substantially L-shaped and has a support rod and an arm with a U-shaped groove in the front face thereof through which the stock passes. The groove is dimensioned to closely receive the stock so that the supported portion therein is not deformed or bent during the bending operation and the external portion of the mandrel is shaped to define the curvature of the bent portions of the stock. The face of the mandrel is tapered to laterally deflect the previously bent end so that the other end may be bent without interference from a previously bent portion.
