Rotor spinning machine comprising a plurality of working positions and a suction device

The invention discloses a rotor spinning machine comprising a plurality of working positions and a suction device. The rotor spinning machine has a plurality of working positions (3) arranged next to each other in the longitudinal direction of the rotor spinning machine (1) between two front ends (2) of the rotor spinning machine, each working position having a plurality of working units for producing and winding up a yarn (31). The working units comprise at least one feed device (4), an opening device (5), a spinning rotor (6) and a winding device (7). The rotor spinning machine further comprises a suction device (8) for producing a negative spinning pressure at the working positions. The suction device comprises at least two separate negative pressure sources (9), a negative pressure source being arranged at each of the two front ends of the rotor spinning machine, and each negative pressure source being connected to a separate negative pressure channel (10) which extends only over a part of the working pos
