Abstract (en)

[origin: EP0365931A1] An air-jet spinning machine with an injector nozzle (31) and a twist nozzle (32), is set to the maximum possible supply speed for a specific desired yarn quality by predetermining a specific spinning tension of the yarn. The maximum possible supply speed is set according to this predetermined spinning tension by varying the injector-nozzle pressure and/or the spinning draft. A plurality of spinning stations (1) is arranged on the air-jet spinning machine. At the spinning station (1), a measuring device for detecting the yarn quality is arranged between the twist nozzle (32) and the draw-off rollers (4). The measuring device is connected to adjusting devices (21, 34, 42) of at least this spinning station (1). In the event of a change of the yarn quality, the measuring device influences at least this spinning station (1) by means of the adjusting devices (21, 34, 42). <IMAGE>
