ABSTRACT:
A hook type coil winding machine is disclosed wherein an occupation rate of a wire which is threaded into a core hole of a head and wound on the head is increased and the deviation of physical properties of cores produced thereon is reduced. Also, the difficulty in winding at a last stage which is caused by the wire which gathers only at a portion of the core hole, is eliminated. In the hook type coil winding machine, a wire is threaded through a small core hole of a head core of a head for a hard disk drive or a video head and wound on the head core. The relative positions of the wire and the head core are controlled for each turn of the wire to achieve aligned winding of the wire to improve the occupation ratio of the wire in the core hole and assure correct winding of the wire by a predetermined number of turns.
