ABSTRACT:
In a coil winding machine, an adjustable wire cutoff assembly is slidably engageable with wire fed from the wire source of magnet wire intermediate said source and a coil winding form. The adjustable wire cutoff assembly is movable away from the coil winding form while wire is being fed from the winding source and is engaged by the wire cutoff assembly, thereby increasing the length of the lead extending from the form to the cutoff assembly over the length it would have if the cutoff assembly were not so moved. The position to which the adjustable wire cutoff assembly is moved can be preset so that leads of various lengths can readily be formed on the same coil winding machine. When the cutoff assembly is moved to the desired position, it is actuated to cut the wire to form a lead of predetermined length.
