<P>PROBLEM TO BE SOLVED: To provide a winding device capable of surely recovering fiber dust flying above a movable cylinder. <P>SOLUTION: A fiber dust recovery device 30 includes an upper nozzle 31 located near the upper opening 13a of the movable cylinder 13 of an unwinding assisting device 2, and a lower nozzle 32 located near the lower opening 13b of the movable cylinder 13. Thus, not only fiber dust flying below the movable cylinder 13 but also fiber dust flying above the movable cylinder 13 is recovered. Also, not only the movable cylinder 13 but also the upper and lower nozzles 31 and 32 are displaced downward following unwinding work from a yarn feeding bobbin B. Thus, as compared with the case that the attitude position of the suction nozzle of the fiber dust recovery device 30 is fixed, the flying fiber dust is more efficiently recovered. <P>COPYRIGHT: (C)2013,JPO&INPIT |
