Abstract: PURPOSE:To enable all kinds of large goods to be packaged reduce substantially a yarn feed changing processes while improving quality and productivity by moving a drive mechanism of a traverse mechanism on an arcuate locus including both of a horizontal reciprocation and vertical movement of the yarn guide port. CONSTITUTION:While a yarn 3 is traversed about a fixed guide 9 by a traverse guide 20 to be taken up by a bobbin 14, a yarn guide port 24 is moved along an arcuate locus including both of the horizontal reciprocation and vertical movement to correct a change in the length L of traverse produced then and maintain the length constant so that the corrective motion for the length of traverse is carried out. Thus, the variation of yarn speed between the traverses is corrected to obliterate the mutual action on the frictional resistance to the yarn 3, so that the variation of tension is not amplified no matter how high the traverse speed is. Also, the tension intensified by fuzy burning or the like is regulated and taken up to proper taking up tension by a feed roller type tension regulator or the like.
