(See FIGS. 6 and 7), the empty bobbin is attached to the cradle 1 by advancing the pintle flange 5b, and at the same time, the twisted wire end is pressed against the flange of the empty bobbin through the elastic plate 5a. (Refer to FIG. 8), thereby fixing the twisted wire end to the empty bobbin. .

[0005]

The wire gripping and cutting device is provided in the vicinity of the elastic plate. Therefore, if a traverse roller that can move laterally, which guides the twisted wire, is moved to the vicinity of the elastic plate, the wire gripping device can rotate freely. By operating the cutting device, the stranded wire end can be made to face the plate surface of the elastic plate, and the stranded wire end can be present between the plate surface and the flange of the empty bobbin. By advancing the pintle flange in this state, the pintle is fitted into the shaft of the empty bobbin and the bobbin is attached to the cradle, and at the same time, via the elastic plate attached to the pintle flange,
The stranded wire end can be pressed onto the flange of the empty bobbin. The stranded wire end is securely and firmly fixed to the flange of the empty bobbin by the elasticity of the elastic plate, and does not come off unless the pressure contact is released.

When the empty bobbin is rotated in this state, the pintle flange and the elastic plate rotate together with the empty bobbin, and the stranded wire slides over the flange of the empty bobbin so that the twisted wire can slide over the flange of the empty bobbin by the guide of the traverse roller. It winds around the body, and the winding is performed.

Although the winding start end of the stranded wire is fixed between the bobbin flange and the pintle flange during winding,
After full winding, the pintle flange retracts, and the bobbin is unmounted, the fixation of the winding start end is also released, and the winding start end is free from the bottom layer of the winding bobbin to the outside of the winding layer. It is exposed in a natural state.

[0017]

The effects of the invention of this application are listed as follows.

(1) Since the winding start end of the twisted wire can be fixed to the bobbin at the same time as mounting the empty bobbin, the fixing operation is simple and there is no time loss. Moreover, since the stranded wire is pinched between the bobbin flange and the pintle flange under the interposition of the elastic plate, the stranded wire is securely and firmly fixed.

(2) The conventional method of fixing the winding start end is changed to a bobbin shape by providing a winding reservoir groove on the outside of the bobbin flange, making a hole in the bobbin cylinder, or providing a notch in the bobbin flange. However, according to the invention of this application, it is not necessary to change the shape of the bobbin at all, and a conventional ordinary bobbin can be used to fix the winding start end of the twisted wire to the bobbin.

(3) Since the winding start end is exposed to the outside of the winding layer of the bobbin, it is possible to continuously supply the twisted wire by connecting with the twisted wire of another bobbin. The length of that exposure is
It is relatively short and necessary and sufficient for connection.
