Method and apparatus of reconnecting for air-flow spinner

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....
