ABSTRACT:
A yarn winding apparatus having a traverse guide to catch a yarn and traverse it in an axial direction of a bobbin onto which the yarn is taken and a pair of yarn release guides which, located inside of and in the vicinity of both ends of the full traverse stroke Wo corresponding to the full width Wp of a yarn package, can go into or out of the path of the yarn. The traverse guide may be either a cam traverser or a rotary blade traverser. The yarn winding is done by repeating the step of repeatedly traversing the yarn over a full traverse stroke Wo and the step of repeatedly traversing the yarn over a narrow traverse stroke W narrower than the full traverse stroke Wo. In the step of traversing over a narrow traverse stroke W, while the yarn is moving from a mid-stroke position toward one end of the full traverse stroke and before the yarn reaches the one end, the yarn is released from the traverse guide, and then while the released yarn is moving toward the other end of the full traverse stroke, the yarn is again caught by the traverse guide and driven toward the the other end. By this winding, excessive winding at both ends of the yarn package can be eliminated.
