ABSTRACT:
A rotor spinning machine has a plurality of spinning stations, each of which comprises an opening roller and a draw-in roller for supplying sliver to the opening roller and each of which is equipped with control devices for individual drives of the draw-in rollers. The control devices each have a connection mechanism, to which an additional control card can be attached for producing effect or novelty yarn with predetermined effects. The control card comprises a processor, which meets the elevated computing power requirements for producing effect or novelty yarn and can be activated via a data bus system.
