PURPOSE:To make man-hours for exchange of cams and others unnecessary also in case of windings with different diameters in a winding machine using a concave cam by constituting nozzles to be installed at a plurality of nozzle holders for winding so that said nozzles may rock with the same phase. CONSTITUTION:Wires W, W1 are wound through spindle 1 central tube 7 nozzles N, N1 by rotation of said spindle 1 receiving energization from a driving part 2 while describing an elliptic path at respective magnetic poles P, P1. Each one of nozzle holders 22, 22A is made to touch a conical body 18 at positions equidistant from the center of said conical body 18. Then, by a vertical motion of the conical body 18, said nozzle holders 22, 22A via support pins 28A, 28B and also the nozzles N, N1 produce an equidistant motion, respectively. As a result, a plurality of installed nozzles N, N1 rock with the same phase forward and backward movement and vertical motion and said nozzles N, N1 can be regulated merely by adjustment of feed of a pole screw 17A. Therefore, man-hours for exchange of cams become unnecessary also in case of stator windings with different diameters.
