The yarn is twisted on the path leading to the center hole, and the number of twists is the same as the number of times the yarn turns around the yarn winding body. With respect to the twist of the yarn, the rotation guide rotates in the reverse direction at a rate of 1/2 in the direction of untwisting, whereby the yarn is reversely twisted by 1/2. Then, in the yarn leading path from the reversing and leading portion of the rotating guide to the fixed guide, the yarn is further reverse-twisted by 逆 from the rotating guide. After all, when the yarn is unwound from the yarn winding body, the twist generated in the yarn is eliminated during a period from the center hole of the rotating guide and the inversion lead-out part to the yarn lead-out path to the fixed guide. . In this case, the rotation guide may be rotated in the opposite direction by half the number of turns of the yarn unwound from the yarn winding body, so that power can be reduced and energy saving can be achieved.
