ABSTRACT:
In a spinning rotor for an open-end spinning unit, the rotor being provided with a bore extending along its axis of rotation to accommodate a yarn extraction tube and being formed to define a fiber collection trough and an intake portion whose cross section widens in the direction toward the trough, the intake portion presenting a radially outwardly extending projecting portion which merges into and defines one boundary of the fiber collecting trough, the region where the projecting portion merges with the trough constituting the region of maximum diameter of the trough and the side of the trough opposite the projecting portion being defined by the spinning rotor bottom surface, the fiber collection trough is kept clean by forming the collection trough so that the radially outermost end of the surface of the projecting portion defines the maximum diameter of the trough, imparting to the portion of the trough adjacent the rotor bottom surface a configuration such that the diameter of the trough in this region is less than the maximum diameter, locating the projecting portion so that the axial distance between the rotor bottom surface and the radially innermost end of the projecting portion is between 1/16 and 1/6 of the maximum diameter of the fiber collecting trough, and providing the outer periphery of the rotor with cleaning bores whose inlet ends communicate with the rotor interior and are disposed in the region of the radially outermost end of the projecting portion.
