Abstract
An open-end spinning rotor has its thinnest wall thickness in the area of its fiber collecting groove. The lateral wall of the open-end spinning rotor comprises an outer contour, which—in axial section—is at least partly convex-shaped. The wall thickness of the lateral wall is increased along a portion of its length by a curved widening contour.
