Abstract

The present invention provides a spinning device that can reduce errors during preparations for joining and that enables stable joining. In a true-twist spinning device S including a hollow guide shaft 15 having a spun-yarn passage 23 through which a spun yarn Y passes, and spinning nozzles 14 for generating whirling air currents near a tip of the hollow guide shaft 15, the spun-yarn passage 23 is formed to broaden toward a yarn ejection side, and yarn picking-up nozzles 29 are provided in the middle of the spun-yarn passage 23 for injecting compressed air. By injecting compressed air from the yarn picking-up nozzles 29 during joining, a suction force is generated in the spun-yarn passage 23 to allow a fiber bundle 6, which have been whirled by the spinning nozzles 14, to be introduced into the spun-yarn passage 23 for yarn picking-up spinning.
