Abstract: This invention relates to a thread traversing device for a winding device of a cross-wound bobbin producing textile machine. Said thread traversing device has a thread guide which is guided in a thread guide rod in the working area and is connected to an individual drive mechanism by a continuous traction mechanism. According to the invention, the thread traversing device (11) has a substantially closed housing (23,) whose inner space (37) in the traversing area (B) of the thread guide (25) is sealed by the continuous traction mechanism (30).

Abstract: Spinning stations of open-end spinning frames are cleaned from time to time to increase productivity, e.g. each time a sliver can change is made although, if the times between the exchange of two cans are too long, cleaning may be performed at a preset cycle. The sliver must be removed from the spinning station for this purpose. To be able to reintroduce a defined length of the removed sliver into the spinning station at the end of a cleaning operation, the end of the sliver is aspirated from between the draw-in roller and the gripping table of the spinning station by means of an aspiration and blower nozzle and pulled out of the spinning box of the spinning station and, after the cleaning operation, the sliver is introduced into the spinning station by means of the aspiration and blower nozzle. The aspiration nozzle has an insert with bores for causing the tip end of the sliver to assume a particular shape.
