Abstract
Open-end spinning device, including a rotor housing, a spinning rotor being disposed in the rotor housing and having an inner surface, a housing cover having a fiber feeding channel formed therein, a thread delivery orifice being at least partly disposed in the cover and having a hard and wear-resistant material surface at thread deflection locations, and a surface layer of wear-resistant material disposed on the inner surface of the spinning rotor, the surface layer having areas of different wearability distributed therein.
