Abstract (en)

A spinning machine (1) includes a draft device (6), an air-jet spinning device (7), and a control unit (10) configured to control operations of the draft device (6) and the air-jet spinning device (7) . When a fiber bundle (F) is split, the control unit (10) changes a drafting ratio to a ratio different from a drafting ratio for a first drafting operation of drafting the fiber bundle (F) in the draft device (6) to cause the draft device (6) to perform a second drafting operation of drafting the fiber bundle (F), and then causes at least one splitting operation to be performed among splitting operations of stopping rotation of at least one of the roller pairs (14, 15, 16, 17), stopping injection of the air in the air-jet spinning device (7), and starting the movement of the air-jet spinning device (7) from the spinning position to the receded position.
