Therefore, a high negative pressure can be generated at each winding position 1. Further, the filter cleaner 12 can be moved at any time, thereby collecting fly waste on the cotton collecting filter 10. In this way, since the filter cleaner is intermittently driven, the cotton collecting blower 4 does not need to be stopped, and The fly waste at the position 1 can be continuously inhaled and collected. As a result, the amount of fly waste recovered can be greatly increased. The configuration of the cotton collecting blower 4, the cotton collecting filter 10, and the filter cleaner 12 is simple, and there is no maintenance problem. It is preferable that the timing for moving the filter cleaner 12 be different for each span or for a plurality of spans. Note that disposing the collection duct individually for each of the plurality of winding units means that, for example, every 12 winding units,
In addition to the mode in which the collection ducts are individually arranged for each of the same number of winding units, the mode in which the winder is divided into different numbers of winding unit groups and the collection ducts are individually arranged in each group is also included.
