Embodiment Construction

[0023] The working spindles of an open-end rotor spinning machine shown in perspective are marked 1 as a whole. A working position 1 of this type is well known and therefore only shown generally schematically, it has an air spinning device 2 and a winding device 3 . A support-mounted, rotatable piecing device 16 is arranged in the region of the so-called yarn output tube 21 of the air spinning device 2, which receives yarn breaks from the cross-wound bobbin 8 by the suction nozzle 4. The retrieved yarn 9, and the yarn ends ready for resplicing.

[0024] In addition, a yarn pulling device 27 is arranged in this area, which not only takes care of delivering the spun yarn 9 from the rotor spinning device during normal spinning operation, but also takes care of pulling a yarn 9 that has been spun into The prepared yarn 9 is fed back into the air spinning device.

[0025] The winding device 3 is, as usual, rotatably supported by a creel 22 for a cross-wound bobbin 8, a drive drum...

Abstract

The invention relates to an open-end open-end spinning machine with a plurality of working positions of the same type, each working position having an open-end spinning device for producing a yarn, a creel and a creel for producing cross-wound bobbins. The winding device of the yarn traversing device, a rotatable suction nozzle that can be supplied with negative pressure on the support, and a yarn end preparation device for re-piecing. Each working station has a winding device that drives the cross-wound bobbin with a drive drum driven by a reversible individual drive mechanism, and a separate motor-driven reel for limiting winding to the cross-wound bobbin. A yarn traversing device for the movement of the yarn; a suction nozzle rotatable by means of a separate transmission between a yarn receiving position in the area of ​​the winding device and a yarn transfer position in the area of ​​the piecing device; each working position is controlled by a separate A motor-driven yarn output device dominates; and a separate drive mechanism can be explicitly controlled by a working position computer.

Description

technical field [0001] The invention relates to an open-end air spinning machine. technical background [0002] For example, an open-end spinning machine such as that described in DE 198 36 065 A1 generally has a plurality of similar working positions aligned with one another. At these working positions, a fiber sliver supplied, for example, from a spinning can is spun into a spun yarn, which is then wound into a cross-wound bobbin. [0003] For this purpose, each working position has a spinning unit and a winding unit. Both the working mechanism of the spinning device and the working mechanism of the winding device are actuated by means of transmissions for the entire machine length. In the area of ​​the spinning device, for example, a tangential drive belt for driving the spinning rotors and a driven drive shaft leading to the machine end side for driving the sliver feed rollers are arranged. [0004] A corresponding straight drive shaft is also arranged in the area of ...
