PURPOSE:To wind up two or more single yarns while twisting them, by turning them compulsorily and swinging forward and backward, leading them to a bobbin tube under rotation, and by winding them up. CONSTITUTION:A bobbin tube 11 is held between a spindle 22 and a tip receptacle 3 and rotated as in a single piece with the spindle 22. This bobbin 11 is extended penetrating the casing 15, and a ring 9 provided with a yarn hole 10 is fitted in this penetrating part. A gear 7 on a spline shaft 13 to be driven shall mesh with a gear 8 formed at the outside circumference of said ring 9 to make it possible for the ring 9 to rotate. The tip receptacle 3 shall also be capable of being rotated by the spline shaft 13 through the gears 4, 5 in meshing. One of the ends of a lever 17, whose middle part is pivoted on a slide plate 21, is set at a side of the casing 15 using a pin 20, while the other end is put in engagement with a cam 19 through a roller 18. This slide plate 21 is reciprocated by a rotating lead screw 14. |
