PURPOSE:To prevent the occurrence of danger in a machine frame by the high- speed rotation of a cutting body always engaged with a spindle as in the conventional apparatus by engaging the cutter body with the spindle is stopping the machine frame at the time of full bobbins, and lowering a ring rail. CONSTITUTION:In stopping a machine frame at the time of full bobbins, the bottom of a ring 19 is engaged with an operating part (16b) of a pushing up lever 16 when a ring rail 18 is lowered. If the ring rail (18) is further lowered in this state, the operating part (16b) is rotated upward to push up a cutter body 26 through a supporting ring 17, and a tapered part 30 above the cutter body 26 is engaged with a tapered part of a flange 29 below a blade 28. Thus, the cutter body 26 is joined to a spindle. At the time of a full bobbin 27, a tail yarn is wound onto a tail yarn winding part 22 while engaged with a yarn capturing recess part 23 after passing through the crosswinding 31. When the full bobbin 27 is pulled out, the tail yarn is pressed to a blade 25 under tension and cut. |
