<p>An object of the present invention is to provide a device and method for a yarn winder which enables a package to be manufactured by taper winding. The present invention provides a yarn winder 1 that forms a package 4, the yarn winder including a contact roller 8 that contacts with the package 4 during formation of the package 4. a traverse device 7 located on an upstream side of the contact roller 8 in an advancing direction of a yarn 2, and a free length changing means 9 for enabling a change in free length FL of the yarn 2 between the contact roller 8 and the traverse device 7 during the formation of the package 4, and wherein during the formation of the package 4, the free length FL is substantially increased to allow winding to be performed such that the resulting package 4 includes a tapered end surface.</p> |
