  • the open-end spinning device comprises an opening roller housing with a receptacle and a fiber guide channel body which can be fixed in the receptacle, via the fiber guide channel individual fibers which are combed out of an opening roller from a master fiber sliver are transported pneumatically to a spinning rotor revolving around a rotor housing which can be subjected to a negative pressure.
  • the receptacle has first means and the fiber guide channel body second means for forming a latching connection.
  • the invention also relates to a fiber guide channel body for a fiber guide channel device, as previously described.
  • the Faserleitkanalkorpus can be fixed in a receptacle of an opening roller housing and has a Faserleitkanal and an inlet region for receiving individual fibers from the opening roller housing.
  • the Faserleitkanalkorpus also has at a longitudinal end to the entry area final face. From the end face of the Faskananalkorpuses extend two substantially mutually parallel tabs away.
  • Fig. 1 schematically shows an open-end rotor spinning device 1.
  • Such open-end rotor spinning device 1 has, as is known, via a rotor housing 2, in which a spinning rotor 3 rotates at high speed.
  • the spinning rotor 3 is supported with its rotor shaft 4 in Lagerzwickeln a so-called support disk bearing 5 and is frictionally driven by a machine-long tangential belt 6, which is acted upon by a pressure roller 7.
  • An axial fixation of the rotor shaft 4 takes place, for example, by a permanently magnetic thrust bearing.
  • the rotor housing 2 which is open towards the front, is closed by a pivotally mounted cover element 8 during the spinning operation.
  • a channel plate 9 is inserted, which rests with a circumferential seal 11 on the rotor housing 2.
