Problems solved by technology

In addition, the friction of the fibers against the walls of the third compacting mechanism has a detrimental effect, which in turn affects the yarn homogeneity
[0017] Although it is pointed out in DE4132919A1 that for certain applications of the drafting mechanism, for example during false twist air nozzle spinning, the compacting mechanism can be constructed in a way that does not limit the fiber strip laterally, but in this case disadvantageously causes the fiber Now it can't even be guided, which determines the flattening movement of the fiber sliver, which in turn determines more fiber waste

Embodiment Construction

[0035] figure 1 The front view schematically shows the air spinning machine 1 . The textile machine has a plurality of work stations or spinning stations 2 arranged next to one another, which are located between so-called end supports 15 , 16 arranged at the end sides.

[0036] as well figure 1 As shown, each of said stations 2 is equipped with feed material, for example fiber strips 4 stored in cans 3 .

[0037] In addition, each station 2 has a drafting mechanism 5, an air spinning device 6, a yarn unwinding mechanism 7, a yarn clearer 8 and a winding mechanism.

[0038] The associated yarn traversing mechanism 9 serves to wind the yarn 10 produced from the fiber sliver 4 in the rotor spinning unit 6 onto the winding bobbin 11 in cross-layer manner.

[0039] The winding bobbins or cross-winding bobbins 11 are held as usual in creels, not shown, and are rotated by bobbin drives, also not shown.

[0040] as well figure 1 As shown, the workstations 2 of the textile machine 1...

Abstract

The invention relates to a drawing mechanism for the air spinning device which is used for drawing and compressing the fiber strips. The front of the drawing mechanism is provided with a pre-compressing mechanism, an air spinning device is arranged on the rear part of the drawing mechanism, and a second compression mechanism in the drawing area positioned in the front of the main drawing area. According to the invention, the main drawing area is internally provided with a third compression mechanism, the width of the channel cross section of the third compression mechanism is greater than that of the channel cross section of the second compression mechanism by 10mm at the most.

Description

technical field [0001] The invention relates to a drafting mechanism for an air spinning device, the drafting mechanism is used for stretching and compacting a fiber sliver, a pre-compacting mechanism is arranged in front of the drafting mechanism and a rear There are air spinning devices in which a second compacting mechanism is provided in the drafting section of the drafting mechanism which is arranged in front of the main drafting section. Background technique [0002] The development of new spinning methods has significantly changed the requirements placed on machine components such as the drafting mechanism. Each spinning method has a number of special requirements, some of which are clearly different from those of other spinning methods. [0003] In ring spinning, which is a common spinning method, yarn consolidation is achieved by giving all fibers a true twist about the yarn longitudinal axis. In the drafting unit arranged at the front, the fiber sliver is usually...
