Embodiment Construction

[0035]FIG. 1 shows one half of an air spinning machine known per se and is denoted by 1 . Such an air spinning machine has a plurality of working positions 2, each of which is equipped with a spinning device 3 and a winding device 4.

[0036] The fiber sliver 6 fed to the spinning can 5 is spun into a yarn 7 in the spinning device 3 , which is wound into a cross-wound bobbin 8 on the winding device 4 . As shown in the figure, the winding device 4 is respectively equipped with a creel holder 9 rotatably holding an empty bobbin 10 or a cross-wound bobbin 8 and a drum 11 driving the cross-wound bobbin.

[0037] Furthermore, each working position 2 has a yarn traversing device 18 , a working position's own suction nozzle 14 and a working position's own piecing device 20 . That is, all working positions 2 are equipped to automatically eliminate yarn breaks.

[0038] Furthermore, the air spinning machine 1 has a bobbin transport device 2 for removing the cross-wound bobbins 8 comp...

Abstract

A method and device for restarting a spinning operation at work stations of an open-end spinning machine after replacement of a cheese with an empty tube by a traveling service unit (16) comprising an auxiliary yarn supply device (21). Each work station comprises a yarn spinning device (3) and a cheese winding device (4) with a creel (9). The auxiliary yarn supply device (21) delivers a starting portion of an auxiliary yarn (24) to a suction nozzle (14), which transfers the auxiliary yarn (24) to a spinning start member (20), after which the suction nozzle (14) pivots to re-take the auxiliary yarn (24) between the supply device (21) and the spinning start member (20) and removes the auxiliary yarn (24) after restarting the spinning operation, whereupon the yarn (7) is brought to the creel (9) of the work station (2).

Description

technical field [0001] The invention relates to a method and a device for rejoining an air spinning machine. Background technique [0002] As is well known, an air spinning machine has a plurality of adjacently arranged working spindles, which respectively have a spinning device for producing yarn and a winding device for producing cross-wound bobbins, which have a creel and a yarn traverse device. [0003] The multiple working positions of this air spinning machine are usually supplied with yarn by means of an automatically working auxiliary device, which is put into work when a certain working position needs to be operated. This operation occurs, for example, when the yarn breaks or when the cross-wound bobbin on a spindle position has reached its specified diameter and must be replaced with a new bobbin. [0004] That is, the auxiliary device as described in DE4443818A1 or DE4313523A1 not only eliminates yarn breaks, but also automatically changes bobbins / empty bobbins....
