Definitions

  • the invention relates to a spinning unit of a rotor spinning machine comprising an opening roller arranged in a cavity of an opening device, whereby between the surface of the circumference of the opening roller and the circumferential wall of the cavity of the opening device, a channel for the transport of opened fibers is formed, into which a fiber sliver inlet opening opens in the direction of the opening roller rotation, a cleaning opening, which is connected to a channel for removing trash from the transport channel, and a fiber outlet opening, which is connected by a fiber outlet channel to a chamber of a spinning rotor.
  • the circumferential wall 23 of the opening device 2 continues along the opening roller 20 as far as to the inlet opening 230 of sliver in the direction X downstream of the fiber outlet opening 232.
  • the entire circumference of the opening roller 20 is surrounded by the circumferential wall 23 of the opening device 2 with the respective openings 230, 231, 232.
