To provide a spinning machine which can efficiently remove spun yarn remaining on a yarn accumulating roller due to generation of a yarn defect in which yarn strength is low.

The spinning frame includes a spinning device, a yarn clearer, the yarn accumulating roller, a suction opening, a suction device, and a unit controller. The spinning device produces the spun yarn by applying twists to a fiber bundle. The yarn clearer is arranged downstream of the spinning device and detects a yarn defect in the travelling spun yarn. The yarn accumulating roller is arranged downstream of the yarn clearer and temporarily accumulates the spun yarn by rotating while winding the spun yarn around an outer peripheral surface thereof. The suction opening of the suction device is arranged near a base end of the yarn accumulating roller. The suction device can generate suction airflow at the suction opening. The unit controller delays a stoppage timing, which is a timing at which feeding of the spun yarn is stopped, when the yarn clearer detects a prescribed yarn defect in which the yarn strength is low, compared with when other type of yarn defect is detected, and stops the yarn accumulating roller after the stoppage timing.
