Abstract

PURPOSE:To automatically remove nozzle clogging by retreating a nozzle unit for twisting fiber bundle during recovery action of end breakage, advancing a suction mouth of suction pipe and a rotary cleaning member and removing clogged fiber waste in a nozzle by these operations. CONSTITUTION:A nozzle unit 7 for twisting fiber bundle is separated from a draft part 5 by yarn suction caused by shaking of a shaking arm 14 and a hollow part 5 is formed at a front roller side 4. A suction mouth of a suction pipe 21 connected to a dust collecting box 22 and a rotary cleaning member 60 are shaken so that they reach a hollow part 15 and fiber dust in the nozzle is swept out by operation of the rotary cleaning member. Fiber waste attached to the rotary cleaning member and fiber waste, short fibers, etc., in the vicinity of suction mouth of the nozzle unit are sucked and removed by cleaning through suction air flow of the suction pipe.
