Embodiment Construction

[0032] The working positions of the air spinning machine shown in the front view in FIG. 1 are generally indicated by reference numeral 1 . As shown in the figure, the working positions 1 each have an air spinning device 2 and a winding device 3 which are known per se and are therefore only shown schematically. Furthermore, at each working position 1 there is a piecing mechanism 16 , a yarn breakage detector 26 and a yarn unwinding device 27 . The rotatably mounted piecing mechanism 16 arranged just before the yarn unwinding tube 21 of the air spinning device 2 pre-treats the yarn 9 sucked back by the suction nozzle 4 from the cross-winding bobbin 8, for example after a yarn break, in order to re- connector. Then, the yarn unwinding device 27 returns the prepared yarn 9 to the air spinning device 2 through the yarn unwinding tube 21, where, as known, the yarn is connected to a surrounding fiber loop.

[0033] As usual, the winding device 3 comprises a creel 22 holding a cros...

Abstract

The invention relates to an air-flow spinner having a plurality of identical work stations, wherein each work station (1) comprises: at least an air-flow spinning device for producing a yarn; a winding device with a creel, a yarn cross-winding device for producing a cross-winding pony roll; a vacuum-chargeable, pivotably seated suction nozzle; a device for preparing a yarn end for piecing again, and a yarn guide device fixed thereon. According to the invention, the yarn guide device and a yarn catch element (7) fixed on the nozzle (4) and being movable by the nozzle cooperatively retrieve the yarn (9) from the cross-winding pony roll (8) and return the yarn to the spinning device (2).

Description

technical field [0001] The present invention relates to air spinning machines. Background technique [0002] For example, as described in the patent DE19836065A1, the air spinning machine usually has a plurality of identical working spindle positions arranged side by side in rows, each of which has an air spinning device and a winding device. This means that, on each working position of the spinning machine, a fiber sliver fed into a can, for example, is spun into yarn by means of an air spinning device, and then the yarn is wound into a yarn by means of a winding device. A cross-wound bobbin. [0003] In addition, yarn is supplied to the working spindles through an auxiliary device that can move along the working spindles of the air spinning machine. When a fault occurs on a working spindle, such as a thread break, the auxiliary device is automatically put into work. In such a case, the auxiliary device is moved to the relevant working position and positioned there and pi...
