BACKGROUND OF THE INVENTION.

An adapter of this type constitutes a prior art based on DE '. ! 5 ·

the fiber feed channel region has adapted to both different fiber materials and rotor rotor spinner dimensions. In particular, they are adapted to accommodate different diameters of the spinner plate. This rounding may optionally be formed on said adapter with a constant radius.

Spinning rotor speeds have been steadily increasing in recent years, so that in order to keep the spinning force of the spinning fibers in the spinning rotors within a predetermined range, the spinning rotor diameter is increasingly smaller. This makes it increasingly difficult to supply channel viákno not yet proceeded to that rotor projecting respectively, taking into account the diameter and ¹ dppřádacího dppřádací inside the thread. Also, the transport, inwardly decreasing, also does not reduce the rotor draw-off nozzle ίο of the rotor directed through the fiber feed channel within the spinning rotor if: • · · · · · · · · · · · · · · · · · «:::::::::: · · · · · · · · · · · ·

SUMMARY OF THE INVENTION

AND

SUMMARY OF THE INVENTION The object of the invention is to provide an adapter of the aforementioned type for very small spinning rotors with a diameter of, for example, less than 30 mm and to take account of manufacturing aspects. í i

The problem is solved in that the adapter consists of at least two parts which comprise a section of the end region of the fiber feeding channel and which are mutually spogated at the disconnection point such that the two sections at the disconnection point form an obtuse angle with each other.

Instead of continuously curving the fiber feed channel at the known adapter, the end region of the fiber feed channel is now available, whose sections can be designed with respect to manufacturing technology, especially when running straight. The end region of the fiber feed channel is angled practically inside the spinning rotor when the disconnecting point of the two fiber feed channel sections is already inside the spinning rotor. The two sections can be tapered. The two-part adapters distributed in this way can achieve an extreme narrowing of the fiber feed channel up to the grooved orifices of the fiber feed channel. The orifice can then be oriented more tangentially to the peripheral direction of the spinning rotor together with the last section of the fiber feeding channel, whereby the fibers can be targeted specifically in the case of particularly small spinning rotors.

According to a variant of the embodiment of the invention, one of the two parts forms the actual adapter and the other part forms the insert in

-3-adapter. The insert may preferably be formed as a segment or also as a housing-shaped part. The insert comprises the last section of the feed channel for its mouth.

as well as fibers,

In particular, when the insert is formed as a housing-shaped part, it may also comprise an inlet region of the fiber withdrawal channel, as well as being formed as a support body for the yarn withdrawal nozzle. '*

DETAILED DESCRIPTION OF THE INVENTION

In Fig. 1, the spinning rotor 1 of the spinning device as well as some components in the peripheral region of the spinning rotor are shown in dashed lines.

• to * to · to · to · to ·

- 4 i t

The spinning rotor 1 consists in a known manner from the rotor ¹ and plates 2 and the shaft 3 is mounted} e and f i driven by a not fashion. In operation, the rotor plate 2 also circulates in a known manner in the rotor housing 4, in which the vacuum / open front side 5 of the rotor plate 2 is closed by a removable cover 6 during operation. it

; -and

The adapter 6, which is shown in solid lines and shown as a replaceable extension, has a substantially rotationally symmetrically designed adapter 8 which partially projects into the rotor plate 2.

·· í í

In this lid 6 there is a sub-part 9 of the fiber supply channel 10 that extends from; In this case, the arrow A shows the direction A of the fiber transport. The transport of the fibers takes place in a known manner by means of a vacuum.

The end region 11 of the fiber feeding channels 10 facing the rotor plate 2 is located in the adapter 8.

The mouth 12 of the fiber supply channel 10 projects inwardly ^{1 of the} rotor plate 2. On the cylindrical peripheral surface 13 of the adapter 8 there is an inlet opening 14 of the end region of the supply channel

Even for fibers, it is connected to the outside by means of an expansion joint; of the fiber supply channel 10.

The orifice 12 of the fiber feed channel 10 lies at a slight distance in front of the sliding surface 15 of the rotor plate 2. The sliding surface 15 conically extends conically from the open front side 5 of the rotor plate 2 to the fiber collecting groove 16. fibers and collected there into a ring of fibers. In the collecting groove 16 '(the thread formed is withdrawn in a known manner through the exhaust nozzle

17, which is located on the adapter 8 concentrically with the shaft 3.

spinning rotor 1. Next to the end region 11 of the feed line 4

(the duct 10 also comprises the inlet region 18 of the yarn draw-off channel. The yarn draw-off nozzle 17 is mounted on the adapter 8 by means of a plurality of permanent magnets 19.

As already mentioned, the adapter 8 is formed on the cover 1

as a replaceable attachment. The reason for the interchangeability is to adapt the end region 11 of the fiber supply channel 10 to the different fiber materials and to the different dimensions of the rotor plate 2 of the spinning rotor 1. In particular, it is possible to adapt

This makes it possible to waive undesirable compromises in the fiber supply in favor of the yarn quality. AND

On the side of the adapter 8 facing away from the spinning rotor 1, a planar annular surface 20 is provided, which serves as a bearing surface of the adapter 8 on the bearing surface 21 of the cover 6. The force to secure the adapter 8 on the cover 6 is generated in the form of a threaded bolt 22. The threaded bolt 22 is screwed into the bore in the adapter 8 formed parallel to the exhaust duct)

for thread.

and

Referring to FIG. 2, it can be seen that the transport direction Á in the vicinity of the mouth 12 of the fiber feed channel 10 varies in terms of the increasing component in the B direction of the spinning rotor 1. This circumferential direction B coincides with the spinning direction of the spinning rotor 1. .

In order to make the fiber filament 10, the part 23 comprises to form the end region 11 of the supply duct with as large a component as possible in the direction B of the adapter 8 from at least two parts, of both parts 23, 24 has a respective section

25, 26 of the end region 11 of the fiber supply channel 10. Mezi ι

the two sections 25 and 26 are the disconnecting points 27, which at the same time are the disconnecting points between the first part 23 and the second part 24. At this disconnecting point 27 the two sections 25, 26 of the fiber feeding channel 10 form an obtuse angle. J l ·

Due to this embodiment by means of two parts 23 and 24 of the adapter 8, especially in the case of small spinning rotors 1, it is possible! ·! to direct the end region 11 of the fiber feeding channel 10 as tangentially as possible to the sliding surface 15 of the spinning rotor 1. The breaking point 27 in the fiber supply channel 10 at the cut-off point 27 and the condition that the cross-section of the fiber supply channel 10 at the mouth is the smallest can be particularly technologically

I. simply make using a two-piece adapter 8. (

As can be seen in particular from FIG. 2, the two sections 25, 26 extend in a straight line and moreover are tapered. The orifice 12 is located in a second part 24, positioned as a segment 28 in the first part 23. Because of this segment 28, it is advantageously possible that the opening 27 is between the two sections ¹ , 25 and 26 of the supply channel 10 for. fiber during operation inside the spinning rotor 1.. j.

and

In the embodiment of FIGS. 3 and 4, the adapter 8 is two-piece, wherein the second other housing part 29 and the sleeve-shaped insert are centrally inserted into the first other part 331 in the form of the adapter itself facing the spinning rotor 1. The second housing part 29 forms a support body for the draw-off nozzle 17. ' for the yarn, the second other part 29 also comprising the inlet region 18 of the yarn withdrawal channel. Also in the embodiment of FIGS. 3 and 4, a different disconnection point 32 is formed in the end region 11 of the fiber feeding channel 10 at which they are pressed together at an obtuse angle

Both other variants of the section 31, sections 30 and 31 of the fiber feed channel 10. In this case, however, the length of the last, that is, the second other

Even longer than the embodiment described above.
