摘要： A false twist device (17) for an open-end spinning device (1) to introduce a false twist in a yarn (7) has a largely tubular carcass (20) and several false twist edges (19) arranged behind one another in yarn draw-off direction (G) and inclined by an angle (α) in the carcass (20) with regard to the yarn draw-off direction (G). The several false twist edges (19) protrude in such a way into the interior of the tubular carcass (20) that the yarn (7) experiences a deflection in each one of the false twist edges (19). Additionally, the several false twist edges (19) are arranged offset in such a way in the carcass (20) in circumferential direction that the yarn (7) simultaneously experiences a spatial deflection compared to its regular yarn draw-off direction (G) through the successive deflections on the several false twist edges (19). An open-end spinning device (1) of a rotor spinning machine (2) with a yarn draw-off nozzle (16) has a false twist device (17) arranged downstream from the yarn draw-off nozzle (16) in yarn draw-off direction (G). In a method for introducing a false twist in a yarn (7) generated in an open-end spinning device (1) of a rotor spinning machine (2), the yarn (7) is drawn off through a yarn draw-off nozzle (16) and pulled through false twist edges (19) in a false twist device (17) arranged downstream from the yarn draw-off nozzle (16), as a result of which the yarn (7) is imparted a false twist. The yarn (7) is exposed to a spatial deflection compared to its regular yarn draw-off direction (G) through the false twist edges (19), in which case an additional false twist is imparted to the yarn (7).

摘要： A yarn withdrawal nozzle for an open-end rotor spinning arrangement is provided which includes a spiral-shaped surface in the yarn deflecting area which extends essentially over the entire yarn deflecting area and designed as a continuous spiral without interruptions. In addition thereto, the nozzle throat of the yarn withdrawal nozzle includes a further surface with structure downstream of the spiral-shaped surface, including rounded notches or curved humps. Both the spiral-shaped surface and the downstream structure are so designed that they are capable of transferring forces to the yarn without damaging same. The yarn withdrawal nozzle is moulded with a mould separation provided in an area downstream of the nozzle throat to facilitate assembly.

摘要： An open-end spinning device comprises a spinning rotor (21) rotating in a rotor housing with a spinning insert (24) supported rotatably with respect to the spinning rotor (21) coaxially to the rotor axis (33). The spinning insert (24) can be caused to rotate as a function of the rotary motion of the spinning rotor (21) via a contactless entrainment of the spinning insert (24) by means of permanent magnets (32) attached to the spinning insert (24). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert (24) in the spinning rotor (21) are achieved.

摘要： At least one circular ridge, which projects upwardly beyond the surface of the navel of the thread delivery device, is placed in the path of yarn being removed from the peripheral wall of the spinning chamber and delivered to the throat of the navel. The ridge has a height of at least 0.003" and is radially so located in proximity to the edge of the navel that the yarn being formed and lifted from the wall of the spinning chamber first engages the navel at the ridge.
