Abstract
The ring spinning machine has separate drives for the spindles, the delivery rollers and the other rollers of the drafting device. The inverters of the corresponding drive motors are fed from a D.C. intermediate circuit so that all the drives stop simultaneously, thus obviating thread breakages. A disc brake is electrically coupled to the intermediate circuit to prevent rotation of the delivery roller of the drafting device.
