Method and apparatus for drawing off the yarn from the fibre-collecting groove of the rotor of an open-end rotor spinning apparatus

摘要

To improve the yarn structure, whilst at the same time ensuring high spinning stability, a lower false twist or a shorter tie-in zone (11) is imparted to the yarn (10) during passage through the fibre-feed zone (9) than outside the fibre-feed zone (9). This takes place, for example, in that the yarn (10) is guided via a region (44) of the draw-off nozzle (14) which has a lower coefficient of friction relative to the yarn (10) than the remaining region (51). <IMAGE>
