  • the channel plate adapter In a recording of the cover element, by means of bolts, pass through the corresponding through holes in the cover element, the channel plate adapter interchangeable fixed.
  • a cylindrical pin is provided, which is embedded in a bore of the cover element and corresponds with a corresponding fitting bore on the back of the channel plate adapter.
  • a disadvantage of this known open-end spinning device is especially the somewhat complicated type of attachment of the channel plate adapter.
  • the DE 195 24 837 B4 described open-end spinning device has a pivotally mounted lid member for closing the rotor housing during the spinning operation, wherein the lid member in addition to the well-known lip seal member also has a receptacle for a channel plate adapter.
  • the channel plate adapter is locked in this recording by means of a bar spring so that the channel plate adapter can be removed if necessary by bending back the bar spring quickly and easily.
  • the rod spring fixed to the cover element grasps for locking the channel plate adapter in a Tangentialnut, which is incorporated in the conical contact surface of the bearing body of the channel plate adapter.
  • the DE 196 17 527 A1 concerns, for example, an open-end spinning device in which the channel plate adapter is fixed in the installed state both positively and positively in a receptacle of the lid member.
  • a magnetic coupling is provided in this case, while the positive connection via a centrally arranged threaded connection.
  • the channel plate adapter is fixed purely magnetically in the associated receptacle of the cover element and, if necessary, can be pressed out of the receptacle by means of a special mechanical punch.

  • the associated channel plate adapter has on its back on a central extension, which is equipped with outwardly projecting abutments for a fastener.
  • the rear projection penetrates a corresponding hole in the receptacle of the lid member and is acted upon by a fastener arranged on the cover element so that the conical bearing body of the channel plate adapter is uniformly or almost evenly pulled into the receptacle of the cover element, the bearing surfaces correspondingly conical are formed.
  • the bearing opening in the cover element is designed so that the channel plate adapter can be installed from the outside.
  • the channel plate adapter can be inserted even with the spinning device in the bearing bore and fixed there by a special locking element.
