To easily cut a sliver when changing cans after the stop of a full can, and to stop operation at the stop of the full can so that there are not generated a variation in the thickness of the sliver at the restart of a comber and a risk of the occurrence of the shortage of the sliver.

A control device 36 decides the state of a coiler tube 31a and a nipper device based on a signal detected by a coiler tube state detection means and a nipper device position detection means when the full can is stopped. Then, the control device 36 controls a main motor M1 and a coiler motor M2 according to a preset full-can stop program so that the nipper device is stopped in a state that a detaching roller nips a fleece continue to a lap and so that a coiler disk 31 is stopped in a stop area where the coiler tube 31a is suitable for cutting a sliver S.
