PROBLEM TO BE SOLVED: To surely and rapidly carry out threading operations of a fiber bundle through a spinning member having a spinning nozzle part and a hollow guide shaft unit. SOLUTION: A real twisted yarn is spun by using a swirling air stream from a swirling nozzle acting on a tip 16a of a hollow guide shaft unit 16 in a usual spinning state. A suction stream is produced in a tip opening 16b of the hollow guide shaft unit 16 in addition to the swirling air stream when carrying out yarn finding operations to thereby suck a fiber bundle 1 fed to the vicinity of the tip opening 15b into the hollow guide shaft unit 16 by the suction stream. Thereby, the percentage of success in piecing is improved.
