A wire loop stitching machine includes a reciprocating drive coupled to a staple-forming and drive means and to a wire feed means for feeding a length of staple wire to a holder and severing it. A bender forms the wire over the holder into a generally inverted U-shaped staple. A supporter with a rounded projection is then inserted between the legs of the staple and a recessed driver deforms the bight portion of the staple over the projection into a curved loop portion and then drives the formed loop staple into an associated workpiece, retracting the supporter in the process.
