Accumulation avoidance device; of fiber abrasion during ringless spinning

The invention relates to a device for avoiding the accumulation of fiber abrasion during ringless spinning of Fiber sliver in a spinning chamber, which consists of a vacuum spinning turbine and a combing element arranged coaxially with the turbine.

In ringless spinning of fiber slivers, when the fed sliver is dissolved, the result is from staple fibers into individual fibers in the spinning chamber fiber abrasion that affects the quickly due to the rotating Auskämisorgan and the exhaust nozzle is. This abrasion is caused by the existing flow conditions in the Fssersanaelrinne of the spinning turbine and in the inner contour of the combing organ and cannot be removed *

As soon as such a mass of fiber abrasion is built up has that it can no longer hold on »it crumbles and relatively large pieces of dirt get into the fiber collecting channel the spinning turbine in which yarn formation is disturbed will. Unwtt <shfcsii can also arise, which are disadvantageous affect the spinning turbine Xager.

In order to avoid this deficiency, it is provided according to the invention, that the open part of the business: orge ns am änd mit a disc is covered. The disc takes the cover Appropriately flush with the outer contour of the combing organ.

The disc can rotate with the combing organ or it can be attached to the bearing journal of the combing organ as a stationary frame be.

The spinning turbine can have radial and / or somewhat exial bores for sucking off the thrown off fiber dust. The radial bores are located in the inlet part. The axial bores are provided on the flange side near the fiber collecting channel.

In the drawing, the subject matter of the invention is in one embodiment shown. Show it:

Fig. 1 shows the previous arrangement of a spinning turbine with a combing element and

Fig. 2 shows the improved arrangement according to the invention.

The known device according to FIG. 1 for eliminating fiber abrasion in the ringless tensioning of fiber slivers in the Spinning chamber, consists of a vacuum spinning turbine 2 and a combing device 1.

During ring-free spinning of fiber roving 10 with this spinning device; ,, in which the combing element 1 is arranged coaxially to the spinning turbine 2 , when the fed fiber roving 10 is broken up from staple fibers into individual fibers, due to the rapidly rotating combing element 1, and a non-roped and differently designed take-off nozzle, ah which the thread being formed unrolls, in the spinning chamber 3 as it abraded.

This process of deposition of the fiber abrasion on the inner contour 6 of the rotating combing organ 1 continues until the mass of the fiber abrasion has developed so strongly that it can no longer hold on to the inner contour 6 due to the forces acting on it , crumbled off to be thrown into the Fasersammeirinne 4- of the spinning turbine 2 as a relatively large dirt. However, since the yarn is formed in the fiber collecting channel M-, the throwing in of dirt particles can result in broken ends and an additional imbalance affect the spinning turbine 2 and thus the spinning turbine bearing.

As can be seen from Fig. 2, the existing version 1 is improved in that the inner contour 6 of the combing element 1 is covered by a disk 7. By the Covering the inner contour 6 of the Äuskämpforgans 1 is a. large part of the air turbulence is transformed into a laminar flow. Since the bottom surface of the combing organ formed by the disc 7 1 and the flange-side inner contour 9 of the spinning turbine are largely parallel and have the same direction of rotation practically created a laminar air flow between the two surfaces of rotation. The fiber abrasion occurring in the spinning process is now continuously either from the cover plate 7, which is designed as a centrifugal disk, onto the fiber roll surface 5 of the .Spinning turbine 2 to be spun from there in Yarn "11 to be spun in continuously, or by the one in the spinning turbine 2, either in the inlet part 5 bores 12 and / or flenschneits near the Fasersammelrir.ne 4-der Spi'inturbine 2 existing bores 13 rb ^ eRaugto
