ABSTRACT:
The bottom wall of a cup-shaped rotor for a freed-fiber spinning device has a flat central portion surrounded by an inclined annular portion. The lateral wall of the cup has the shape of a cone frustum, the small diameter of which is located on the edge of the cup opening. Waste removal holes are formed in the annular portion of the bottom wall in the immediate vicinity of the lateral wall. Waste material is thus discharged to the exterior of the rotor under the action of centrifugal force.
