Abstract: PURPOSE:To prevent the generation of excessive tension by providing a slip coupling which adjusts the rotational speed of a guide tube for applying twisting torque to a wire, between a rotational drive source and the guide tube so that the twisting torque is uniformly maintained. CONSTITUTION:A slip coupling 10 is disposed between a spiral guide tube 5 having one end 5a opened to the top of the rotary shaft of a reel 3 and the other end 5b opened to the periphery of the reel 3 and a drive source 11. A transmission 9 is driven through the slip coupling 10 when the drive source 11 is operated, and a wire 1 introduced into the guide tube 5 is applied with one twist within the elastic limit, per one turn of the wire 1 with respect to the reel 3 while the wire 1 is wound up onto the reel 3. With this arrangement, the twisting torque of the wire 1 may be uniformly adjusted, the generated tension of the wire 1 is limited and the feed speed thereof is also uniformly maintained, thereby the generation of excessive tension is prevented and the finishing of the winding is made to be satisfactory.

The TR33 is then conducted, by which the driving voltage of the motor 39 is decreased and the rotating speed is decreased. The cut ends are thus quickly and easily brought to the prescribed space and therefore the working efficiency is improved.
