Definitions
- the invention relates to a receiving element according to the preamble of claim 1.
- DE 33 43 217 AI describes, for example, such a thread take-off nozzle which can be interchangeably fixed in a fiber channel plate via a thread arrangement.

- the generally metallic base body has one
- Inlet judge which - for example, is made of a ceramic material, is glued.
- the base body has an external thread for
- thread draw-off nozzles have proven themselves in practice in principle, but have the disadvantage that the replacement of such thread draw-off nozzles is relatively time-consuming and that a tool is always required to change these thread draw-off nozzles. It has therefore already been proposed to fix thread take-off nozzles magnetically to the fiber channel plate or to a fiber channel plate adapter embedded in the fiber channel plate.
- Such magnetically fixable thread take-off nozzles are described in detail, for example, in DE 27 45 195 AI, DE 37 29 425 AI, DE 195 02 917. C2 or DE 195 32 735 AI.
- such thread draw-off nozzles consist of a ferromagnetic thread draw-off nozzle holder, in whose through-hole a ceramic inlet funnel is glued
- the thread take-off nozzle holder has a cylindrical shaft and an annular head part. Centering lugs are arranged in the area of the head part, which correspond to permanent magnetic pins which are embedded in corresponding bores in the fiber channel plate. In the installed state of the thread take-off nozzle, the thread take-off nozzle holder with its cylindrical shaft is positioned in a corresponding through hole of the fiber channel plate and reliably secured against axial and rotational displacement by the ferromagnetic centering lugs or the permanent magnet pins.
- Spinning device described with a special fiber channel plate which has a flange-like extension on the back, on which a thread take-off tube can be detachably fixed.
- the fiber channel plate has one through the flange
- This internal thread has a corresponding one
- Thread take-off nozzle covers the receiving element over its entire length and is supported at the end in the stepped
- the invention has for its object to provide a receiving element that also allows magnetically lockable thread take-off nozzles to be fixed in a fiber channel plate, which was originally designed to accommodate screw-in thread pull-off nozzles.
- the receiving element designed as an adapter has the particular advantage that fiber channel plates that have a central
- Threaded hole to accommodate a screw-in
- the adapter has an external thread and a
- the inside diameter of the through hole is on the
- Thread take-off nozzle matched.
- the adapter also has center holes for
- Thread take-off nozzle
- the adapter according to the invention makes it technically somewhat outdated without much time and material expenditure
- Thread take-off nozzles can be used.
- the adapter has an annular head part which, in the installed state, is at least partially positioned in a corresponding recess in the fiber channel plate.
- Centering bores are arranged in the head part, which correspond to the centering approaches of the thread take-off nozzle and thus ensure an exact, reproducible installation position between the thread take-off nozzle and adapter.
- the embodiment shown in FIG. 4 enables optimal positioning of the thread take-off nozzle in the fiber channel plate with respect to the spinning rotor of the open-end rotor spinning device.
- the use of the adapter according to the invention enables problem-free, reproducible installation and removal and secure fixing of magnetically lockable thread take-off nozzles in fiber duct plates, which are equipped with a central threaded bore.
- the first embodiment provides for permanent magnet pins to be positioned in the centering bores of the head part.
- the permanent magnetic pins are, as described in claim 4, arranged sunk.
- the adapter according to the invention has a fastening part and a centering ring which is rotatably mounted with respect to the fastening part.
- the centering ring is equipped with centering holes and at least one centering pin, the centering pin corresponding to a corresponding centering hole in the fiber channel plate (claim 6).
- the centering pin on the centering ring reliably fits into the corresponding centering hole • in the fiber channel plate and thus specifies the exact position of the centering holes of the centering ring.
- centering holes of the centering ring are positioned exactly in the area of permanent magnetic pins which, as stated in claim 7, are fixed in corresponding holes in the fiber channel plate.
- the adapter is also equipped with a 0-ring seal (claim 8).
- the adapter is preferably made of aluminum.
- This material is not only very corrosion-resistant, but also relatively easy to machine and relatively inexpensive.
- 1 is a side view of an open-end rotor spinning device
- FIG. 2 shows the detail X of Figure 1 on a larger scale, with a first, one-piece embodiment of the adapter according to the invention
- FIG. 3 shows the adapter according to FIG. 2 with a magnetically lockable thread take-off nozzle holder and a fiber channel plate equipped with an internal thread, partly in section
- 4 shows an alternative, two-part embodiment of the adapter according to the invention with a magnetically lockable thread take-off nozzle holder and a fiber channel plate equipped with an internal thread, partly in section
- FIG. 5 shows the arrangement according to FIG. 4 in perspective.

- Rotor housing 2 in which during the spinning operation
- Spinning cup of a spinning rotor 3 rotates at high speed.
- the spinning rotor 3 is with its rotor shaft 4 in the
- Bearing gusset of a support disc bearing 5 is supported and is supported by a machine-long tangential belt 6, which by a
- Pressure roller 7 is turned on, applied.
- the rotor shaft 4 is preferably axially fixed via a permanent magnetic axial bearing 18.
- the rotor housing 2 which is open towards the front, is closed during the spinning operation by a pivotably mounted cover element 8, into which a fiber channel plate 12 with a seal 9 is inserted.
- the rotor housing 2 is also connected via a corresponding suction line 10 to a vacuum source 11, which generates the spinning vacuum required in the rotor housing 2.
- a fiber channel plate 12 is arranged in the cover element 8, preferably exchangeably, in which, if necessary, also a replaceable one Thread take-off nozzle 13 is fixed, to which a thread take-off tube 15 connects.
- the fiber channel plate 12 also has, as usual, the mouth region of a fiber guide channel 14.
