<p>PURPOSE:To contrive reduction in number of processes by a method wherein a wire material is pressure-welded to the bottom face of an annular groove, the wire material is fed and wound in the annular groove, the wire material is engaged at a crossover part, and the wire material is wrapping-connected to a connection pin. CONSTITUTION:A feeding nozzle 15 is rotated along an annular groove 11 as shown by the arrow E in the diagram, the wire material 9 brought out from the tip of the nozzle in association with the movement of the feeding nozzle 15 is pressure-welded to the bottom face of the annular groove 11 by a pressure-welding roller 16, and the winding having the prescribed number of winding is formed in the annular groove 11. Subsequently, after the feeding nozzle 15 has been pulled out at the crossover part of the annular groove 11 and the axial-directioned groove 14 along an axial- directioned groove 14 as shown by the arrow F in the diagram in the state wherein the wire material 9 is engaged by a pressure-welding roller 16, a hook pin 20 and the pressure-welding roller 16 are also pulled out. Lastly, a lapping connection is performed by rotating the feeding nozzle 15 around the remaining connection pin 13 as shown by the arrow G. As a result, the winding work to the extent at which an end part process is completed can be accomplished with few processes.</p> |
