Abstract:
A wire product manufacturing apparatus adapted to receive a wire from a supply and operate on the wire to form a wire product, the wire product manufacturing apparatus comprising a wire guiding section which receives the wire from the wire supply and guides the wire toward wire feeding means which feeds a predetermined length of the wire to shaping means, the shaping means comprising tool sets, each having a wire operating tool controlled by suitable controlling means to sequentially operate on the wire, the improvement comprising a wire rotating section arranged between the wire feeding means and the shaping means to allow the wire to extend therethrough from the wire feeding means to the shaping means, the wire rotating section comprising a wire holding member which comprises a chuck having a wire passage through which the wire extends toward the shaping means, the chuck further comprising a plurality of chuck blocks which are arranged to surround the wire passage and are radially movable so as to selectively clamp the wire extending through the wire passage and through the wire rotating section and driving means which selectively drives the wire holding member to rotate and thus causing an angular displacement of the wire about a central axis of the wire.
