ABSTRACT:
A rotary stapling machine includes a first rotatable roller, a staple retainer mounted on the first roller to retain a U-shaped staple in a predetermined orientation, and a second rotatable roller having a die. The first and second rollers are adjacently positioned and spaced to allow material for stapling to pass between. Rotation of the first and second rollers positions the staple retainer and the die in a coacting position wherein the staple legs are bent toward the staple retainer. The die includes a pair of bending plates pivotally mounted in a slot that communicates with an outer surface of the second roller. The bending plates have forming surfaces that contact the legs of the staple and by pivoting toward the first roller, drive the legs toward the staple retainer and hold the legs in a desired bent position.
