ABSTRACT:
The machine comprises a series of rotatable spindles (3), each of these being associated with respectively one cap-shaped thread guide member (7) rotatable about the spindle axis. A first drive belt (5) serves for turning the spindles (3). A second belt (12) is in contact with whorls (11) on the thread guide members (7). A device exerting contact pressure (13, 14, 15) urges the second belt (12) during operation against the whorls (11) with an adjustable force so that the belt (12) exerts, by means of friction, a small braking force on the whorls (11) running faster than the belt (12). The contact pressure device (13, 14, 15) can be switched over in order to press the second belt (12) against the whorls (11) with a substantially greater force. Upon shutoff of the spinning machine, the contact pressure device (13, 14, 15) is switched over so that the decelerating second belt (12) exerts a substantially greater friction force on whorls (11) and rapidly brakes the thread guide members (7) concomitantly.
