Abstract
The main body (7) of an open end spinning rotor (3) which comprises a main body (7) and a rotor body (6) wherein the main body is carried by a mounting and drive element and has a substantially radial support surface (72) with a centering surface (70) at its outer edge. A centering surface (61) of the rotor body (6) co-operates with the centering surface 70 of the main body. The centering surfaces (70, 61) in the main body (7) and in the rotor body (6) are in the form of a peripheral groove and a peripheral rib, respectively. The support surface (72) and the centering surfaces (70) of the main body (7) have substantially radial slots (71).
