  • 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.

  • 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 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.
