Abstract: A machine for forming windings on electric motor stators, comprising a needle driven with reciprocating rectilinear motion combined with reciprocating rotary motion about its axis. The needle has two opposing points, which are orthogonal to the needle. The needle carries copper wires unwinding from reels in order to deposit the wires in slots in a stator armature. The needle is split into two arms or ends oscillating between a position of substantial parallelism, in which the ends of the points are at a distance apart which is less than the maximum width of the inner cavity of the stator, and a position of maximum divergence in which the ends of the points are at a distance apart which exceeds the distance between the ends of the teeth which frontally retain the windings in the opposite slots of the stator.
