APPARATUS FOR MAKING COILS FOR ARMATURES OF ELECTRICAL MACHINES OR THE LIKE

Armature coils for use in electrical machines are proeuced on a revolving pattern of polygonal outline. A continuous length of wire having a current conducting core surrounded by an insulating sheath is fed nder tension to the peripheral surface of the revolving pattern. A set of pushers cooperate with the pattern to move successively formed convolutions axially of the pattern. A cutting device which severs the wire between selected convolutions to form a succession of coils comprises a finger which orbits about the pattern and a reciprocating device which moves the finger axially at predetermined intervals so that the finger loops the wire between selected convolutions and moves the thus engaged part of the wire against a counterknife which is adjacent to the periphery of the pattern. A removing device strips the insulation off those portions of the wire which are to be severed by the cutting device so that the coils are formed with blank terminals.
