Abstract
An ignition coil winding method for spirally winding an element wire in conical banks of wire turns one by one around a coil bobbin provides in particular that a nozzle can vertically move toward and away from the coil bobbin according to a changing winding radius and can swing in the direction normal to the longitudinal axis of the bobbin to maintain constant tension of the element wire. This method also uses a nozzle whose opening diameter is 2 to 6 times larger than that of the element wire to eliminate oscillation of the element wire in the nozzle opening.
