ABSTRACT:
A medical staple forming die and pusher punch for use in a staple forming machine. The bend radius of the staple is formed either by the form punch pushing the wire past a set of rollers, or by movable forming dies in conjunction with a tapered or contoured pusher punch. Since the wire is not scrapping on a stationary rail, pulling thin or cracking in its corners is substantially eliminated and the possibility of metal slivers produced by the prior art scrapping methods is substantially reduced or eliminated.
