ABSTRACT:
To prevent yarn from being cut when an operating spinning machine stops, thereby preventing subsequent re-activation from being affected. In a spinning machine for manufacturing yarn by passing a fiber bundle that exits a draft apparatus 1 through a spinning nozzle 2 injecting a swirling air current and then through a twisting apparatus 3 that twists the fiber bundle in a direction reverse to that of the swirling air current, each spinning unit is driven independently, and the draft apparatus 1 can be decelerated or accelerated with the speed ratio of each pair of rollers being maintained. When the spinning is stopped or activated, the draft apparatus 1 and the twisting apparatus 3 simultaneously decelerate or accelerate so as to be simultaneously stopped or activated, and in response to this operation, air injection from the spinning nozzle 2 stops or starts.
