Coil winding machine and method of producing deflection coil

A method of producing a deflection coil by using a coil winding machine, said coil winding machine including:

• bobbin holding means for holding a coil bobbin, the coil bobbin including an inner peripheral surface defining a central bore and two end portions with each end portion having a circumferential guide groove, formed therein, each end portion defining a respective opening into the central bore;
• a nozzle for feeding out a conducting wire for a deflection coil, said nozzle being movable along and through the central bore of said coil bobbin in a center axis direction of said coil bobbin held by said bobbin holding means;
• and a winding guide having at least one winding guide member formed with a tip portion and movable in and out of said circumferential guide groove of said coil bobbin and having a recess forming a stepped portion wherein, when the nozzle moves in the center axis direction outwardly through the opening from the central bore, the stepped portion captures the conducting wire in the recess and, when the nozzle moves in the center axis direction through the opening and into the central bore, the conducting wire is released from the recess;
• said method comprising the steps of:
• engaging said conducting wire fed out of said nozzle with the recess formed by the stepped portion of said winding guide when the nozzle moves in the central axis direction outwardly from the central bore and simultaneously winding said conducting wire in the circumferential guide groove of said coil bobbin;
• and
• releasing said conducting wire from the recess of said winding guide by moving the tip portion of said winding guide in the circumferential guide groove of said coil bobbin and moving said nozzle from one opening to the other opening of said coil bobbin in the center axis direction of said coil bobbin.
