<p>A traverse detection section (70) provided in a yarn winding device (automaticwinder) is arrangedin atraverse region to detect a yarn (21) to be traversed. The traverse detection section (70) includes a light emitting section (72), a reflecting section (74) adapted to reflect light emitted from the light emitting section (72), and a light receiving section (73) adapted to receive the light reflected by the reflecting section (74). The light receiving section (73) and the reflecting section (74) are arranged at positions sandwiching a yarn path, through which the yarn (21) to be traversed passes, and in a region at one end of three regions obtained by equally dividing the traverse region in a package width direction.</p> |
