Compressed air is jetted from an auxiliary nozzle 19e formed in the hollow guide shaft body 19 in addition to the turning air stream during ending operation to produce suction force from an opening 19h formed at the tip of the hollow guide shaft body 19 toward a yarn discharge port 19g to thereby carry out the yarn pick-up spinning. In the method for spinning, the draft ratio during the yarn pick-up spinning is changed from that in the usual spinning state. After completing the yarn pick-up spinning, the changed draft ratio is returned to the draft ratio in the usual spinning state.  <P>COPYRIGHT: (C)2004,JPO
