Abstract

To suppress the consumption of compressed air in a textile machine employing a sequence doffing method. Winding devices 4 are arranged in a plurality of columns and a plurality of stages. A yarn waste collection device 5 includes a yarn waste transfer pipe 28 provided in each stage, each yarn waste transfer pipe 28 is connected to a plurality of suction pipes 30. Each compressed air switching valve for suction transfer 31 connected to each suction pipe 30 is switched to a state of supplying compressed air for suction transfer during a doffing operation of the winding device 4. An auxiliary compressed air switching valve 41 connected to each yarn waste transfer pipe 28 is switched to a state of supplying auxiliary compressed air when the compressed air switching valve for suction transfer 31 is switched to a supply state. The doffing operations are performed, for each winding device 4, sequentially with a shift at predetermined intervals, and are performed partially overlappingly. The order of the doffing operations can be set such that the doffing operations are performed in the plurality of winding devices 4 in one stage, and thereafter, the doffing operations proceed to the plurality of winding devices 4 in another stage.
