Abstract

A rotor spinning machine has a multiple number of work stations arranged side by side in the longitudinal direction of the rotor spinning machine between two front-side ends of the rotor spinning machine, each of which work stations has a multiple number of work elements for the production and winding of a yarn. The work elements comprise at least one feed device, one severing device, one spinning rotor along with one winding device. Furthermore, the rotor spinning machine has a suction device for producing a negative spinning pressure at the work stations. The suction device includes at least two separate negative pressure sources, whereas one negative pressure source is arranged on each of the two front-side ends of the rotor spinning machine, and whereas each of the negative pressure sources is connected to a separate negative pressure channel that extends in the longitudinal direction of the rotor spinning machine only over a part of the work stations, It is provided that the suction device includes at least two separate negative pressure sources, whereas at least one negative pressure source is arranged on each of the two front-side ends of the rotor spinning machine, and whereas each of the two negative pressure sources is connected to a separate negative pressure channel that extends in the longitudinal direction of the rotor spinning machine only over a part of the work stations. Thereby, each work station has an individual drive, in particular a single electric drive, for the spinning rotor.
