Abstract (en)
[origin: EP1813563A2] The present invention improves the quality of a package (7) by preventing wrinkles in a yarn winding device which forms the package (7) by winding a supplied yarn (4) around a winding tube (6) while applying a tension to the yarn (4) by a tensioning device (30) and traversing the yarn (4) by a traversing device (5). Particularly, in precision winding with a fixed number of winds, in synchronism with an increase in diameter of a yarn layer (7) and a change in a traverse angle (¸), the tension to be applied by the tensioning device (30) is changed. In detail, according to reduction in the traverse angle (¸) calculated by traverse angle calculating means (75), tensioning control means (77) controls to reduce the tension to be applied.
