Abstract

An air spinning device with an injection nozzle and a twisting nozzle is adjusted to the highest possible delivery speed for a desired yarn quality by predetermining the desired spinning tension of the yarn. According to the predetermined spinning tension, the highest possible delivery speed is regulated by changing the injection nozzle pressure and/or the spinning draft. Several spinning stations are installed on the air spinning device. At the spinning station, a measuring device to determine the yarn quality is installed between the twisting nozzle and the draw-off rollers. The measuring device is connected to adjusting devices of at least one spinning station. When the yarn quality is changed, the measuring device, together with the adjusting devices influences at least this spinning station.
