ABSTRACT:
A method of making a shaft seal ring starts with a tube, optionally provided on its outside and/or inside with hydrodynamically-acting return elements, as may be cut from a hollow cylinder. The tube is axially slipped along a form with a continuously increasing diameter until its leading or lower end is shaped into a flange in the radial direction. The flange may be simultaneously joined to a reinforcing ring.
