ABSTRACT:
In a controlled stopping procedure for an open-end spinning machine the fibre feed roller and the yarn delivery rollers decelerate in synchronism. A detector senses a predetermined speed of the yarn delivery rollers after a period of time from starting the deceleration and initiates the stopping of the fibre feed roller. After a further period of time, determined by time delay means, the decelerating yarn delivery rollers are braked. Preferably the yarn delivery rollers have come almost to rest when they are braked.
