- the wind ratio before avoiding ribbon wind is calculated based on the bobbin holder with the largest winding diameter during winding, and the wind ratio after avoiding is such that the bobbin holder with the smallest winding diameter during winding avoids the ribbon wind area. Since the traverse speed Vt is increased as much as possible, for example, winding without ribbon winding is possible even if the winding diameter difference changes during winding or the winding diameter difference is reversed.
- the traverse speed when the winding diameter difference exceeds a predetermined range, the traverse speed must be greatly increased, and the traverse angle force is greatly increased. Since such a sharp and large increase in the twill angle is considered to have an adverse effect on the yarn quality, for example, when a winding diameter difference occurs such that a change in the twill angle occurs by 1 ° or more at a certain ribbon jump diameter. It is desirable that warnings such as warning sounds and warning signals be issued.

- FIG. 1 is a schematic view of an embodiment of a winding device according to the present invention having a plurality of traverse devices.
