摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide a spinning unit capable of suppressing tension fluctuation in winding up filament yarn irrespective of the difference in bobbin diameter by the aid of a simple control system. SOLUTION: This spinning unit has respective rotatingly driving motors 23 and 10 for a funnel 5 and a spindle 7, a bobbin position moving means 30 for making a bobbin 6 undergo a vertical motion and a control section 14 for the means 30, and works so as to wind up a filament yarn Y on the bobbin 6 covered with the funnel 5 supported rotatably and undergoing a rotary driving while making a vertical motion relative to the funnel 5; wherein the control section 14 works as follows: the angle of rotation of a stepping motor 34 is judged by a relevant section 14a, thereby the present position of the bobbin 6 is judged; based on the judgment, the rate of rotation of the motor 23 for the funnel 5 is increased as the bobbin 6 comes close to the upper limit position of its vertical motion range, while the rate of rotation of the motor 23 is decreased as the bobbin 6 comes close to the lower limit position of its vertical motion range.

摘要： PURPOSE: To simplify a yarn ending or spinning initiation operation by suppressing ballooning with a simple mechanical auxiliary means instead of a complicated action of a yarn ending robot. CONSTITUTION: In the operation of yarn ending or spinning initiation in a cap fire spinning machine, a yarn 8 is wound back to a bobbin 4 in a cap 2 engaged with a spindle 5 from a cheese 9, cut with a cutter 10 and an end part of the yarn is pulled into a suction tube 11, then the tube 11 is inserted into a gap between an end of the cap 2 and the bobbin 4. Then, a suction cap 13 is loaded on the cap 2 and the yarn 8 is upwardly sucked through the gap between the end of the cap 2 and the bobbin 4, thus a rotatable roller 17 fitted to a robot is brought into contact with an end part of the cap 2 and the normally and reversely rotating the roller 17 to each the yarn 8 with a catching means 12 formed as a U-letter type hollow finger or hook, then the yarn 8 is guided between a pair of drawing rollers 14, thus cut a place at a prescribed length and the cut end and the tip of a fleece are mutually connected.
