Problems solved by technology

However, it has been found in practice that in service units constructed in this way, although the new yarn is generally securely clamped in the gap between the sleeve disc and the end face of the empty sleeve, there is the danger that, Despite the subsequent pivotally mounted yarn guide element on the yarn laying device, the spun yarn does not immediately return to the empty sleeve again, as a result, the foot yarn is wound next to the empty sleeve , and often it is not possible to use

Embodiment Construction

[0019] figure 1 One half of an open-end spinning machine 1 known per se is shown. Such an open-end spinning machine 1 has a plurality of identical stations 2 arranged side by side, each of which is equipped with a spinning device 3 and a winding device 4 . In the spinning device 3 the fiber sliver 6 stored in the spinning barrel 5 is spun into a spun yarn 7 , which is wound into a cross-wound bobbin 8 on the winding device 4 . As shown, the winding devices 4 are each equipped with a creel 9 for rotatably holding an empty sleeve 10 or a cross-wound bobbin 8 and a bobbin drive roller 11 for driving the cross-wound bobbin. Furthermore, the stations 2 each have a yarn traversing device 18, a suction nozzle 14 of the station itself, and a splicing mechanism 20 of the station itself. That is to say, the station 2 is equipped in such a way that it can automatically eliminate yarn breaks when required.

[0020] The open-end spinning machine 1 also has a bobbin delivery device 12 fo...

Abstract

The service device (16) has an auxiliary thread feeding device (21) for providing an auxiliary thread, where a thread laying device (23) is provided for creating a new thread. The thread laying device has one separately controlled drive for a thread-guiding and deflection lever (34).

Description

technical field [0001] The invention relates to a service unit serving the work stations of an open-end spinning machine. Background technique [0002] It is known that open-end spinning machines have a plurality of identical stations arranged side by side, each station having a spinning device for producing the yarn and a winding device for producing cross-wound bobbins. The stations of such open-end spinning machines are usually serviced by an automatically working service unit which intervenes when an operating situation occurs at one of the stations. Such operational events are for example a yarn break or a cross-winding bobbin at one of the stations reaches its predetermined diameter and has to be replaced by a new empty sleeve. That is to say, a service unit such as that described in German patent DE4443818A1 not only eliminates "normal" yarn breaks, but also automatically performs cross-winding bobbin / empty sleeve changes. In the case of a cross-wound bobbin / empty s...
