PROBLEM TO BE SOLVED: To attain the high-speed spinning of a fine count yarn without thread breakage by drafting the sliver via the drafting mechanism, then guiding the drafted sliver to a twisting mechanism equipped with a funnel that covers the bobbin, as it is driven and rotated, and winding up twisted yarn to the bobbin. SOLUTION: The sliver S is processed via the drafting mechanism 101 into a yarn Y, then the yarn is guided to the spinning mechanism 102 in which the funnel 5 that is rotatably supported by the funnel supporter 21 and has an opening opened at the lower end is arranged so that it may cover the bobbin 6 that is integrally rotatable together with the spindle 7, and the bobbin 6 integrally rotating together with the spindle 7 is rotated by the spindle-driving motor 10, at the same time, the funnel 5 is rotated with the funnel-driving motor 23, whereby the bobbin 6 is vertically reciprocated to the funnel 5, as the yarn Y is twisted, and the twisted yarn Y is orderly wound up around the bobbin.
