Abstract
Abstract A method of and machine for winding armatures wherein the stretches of wire that extend from the flyers of the machine to the commutator tangs to which the starting and ending leads of a wound armature are attached, are gripped and cut close to those tangs, the grip on said wires being maintained while the wound armature is removed from the machine and replaced with an unwound armature core assembly and until the starting leads of the windings to be applied to the unwound core are attached to their respective commutator tangs, and then with the wires still gripped they are cut close to the tangs to which they are attached, whereupon the grips on the wires held thereby are released.
