Abstract

An electric wire is wound as coil turns in slots in electric rotating machinery component such as a stator or an armature. The wire as it is supplied from a nozzle or flyer is guided by movable formers into successive layers of coil turns in the slots without forming an unwanted dead space in the slots. The formers are moved in radial increments to provide successive spaces in the slots for allowing the successive coil turn layers to be neatly laid in the spaces.
