ABSTRACT:
A yarn traverse apparatus for winding a yarn on a bobbin, comprising setting means for setting a limit value of a crossing angle, a traverse stroke, a width of the yarn, and a ribbon occurrence region; means for detecting the number of rotations of the bobbin; means for detecting a winding speed of the yarn; means for calculating a diameter of the package in accordance with the number of rotations of the bobbin and the winding speed of the yarn; means for calculating a winding ratio in accordance with the number of turns of the yarn over two traverse strokes and with the number of turns of the yarn over one pitch corresponding to the limit value of the crossing angle, and varying the winding ratio in steps so that the winding ratio is moved outside the ribbon occurrence region when the package reaches a predetermined value within a predetermined region of the crossing angle; means for calculating the number of traverse strokes in accordance with the number of rotations of the bobbin and the winding ratio corresponding to the package diameter; and a traverse mechanism for traversing the yarn in accordance with an output of the traverse operation means.
