Abstract (en)

[origin: EP0327921A1] In a ring spinning machine with separate drives for the spindles 28, the draw-off rollers 5 and the other rollers 3, 4 of the drawing units 2, the converters 24, 25, 26 of the corresponding drive motors 19, 20, 27 are fed from an intermediate direct-current circuit 30, so that all the drives stop at the same time, thereby preventing yarn breaks. A disc brake 38 is coupled electrically to the intermediate circuit 30. <IMAGE>
