Abstract
An ignition coil winding method for spirally winding an element wire in conical banks of wire turns one by one in both forward and backward directions on a coil bobbin provides in particular that the number of wire turns placed in the reverse descending spiral winding direction is larger than that placed in the forward ascending spiral winding direction, thus forming a reliable coil with no falling-down of the banks of wire turns during the winding operation.
