YARN WINDING METHOD AND YARN WINDING DEVICE

WIPO Patent Application WO/2004/069713

A1

A yarn winding method and a yarn winding device capable of avoiding the winding of ribbon for all bobbin holders even if a difference in winding diameter occurs in any of packages while yarn is wound on the plurality of bobbin holders by one traverse means, the device wherein bobbins (3) and (3’) are fitted to the bobbin holders (1) and (2), the packages (P) and (P’) are wound on the bobbins installed on the bobbin holders while traversing the yarns (Y) and (Y’) by a traverse cam (9), and when any of the bobbin holders reaches a specified wind ratio, a traverse speed in winding is increased so that the wind ratio can avoid a ribbon wind area. The yarn winding device comprises the plurality of bobbin holders whereby the windings of the packages are performed simultaneously and the single common traverse means installed for the plurality of bobbin holders. When the bobbin holder with the largest winding diameter in winding among the plurality of bobbin holders reaches the wind ratio that must be avoided, the traverse speed is increased so that the bobbin holder with the minimum winding diameter can avoid the ribbon wind area to keep all bobbin holders away from the ribbon wind area.
