摘要： An open-end spinning arrangement having a yarn withdrawal nozzle (10), by means of which the yarn is withdrawn form its transition zone within the spinning rotor and is rollingly and slidingly deflected while circulating in contact with the yarn withdrawal nozzle, additionally imparting a false twist. The yarn withdrawal nozzle has a depression (24), which is abruptly offset in the circulating direction of the yarn, by which the yarn loses contact with the yarn withdrawal nozzle (10) in the withdrawal direction of the yarn and over an angular area a of at least 10 degrees. Each time the rotating yarn tail sweeps over this depression, the false twist is completely interrupted and the actual twisting of the yarn at the yarn withdrawal nozzle (10) is cancelled. Yarns spun by means of such yarn withdrawal nozzles (10) have a looser yarn structure and a clearly reduced number of wrap fibers, and make the employment of rotor-spun yarns possible in applications in which preferably voluminous and soft yarns are processed.
