  • Method of cutting a helical cut seal
    Patent number: 5172474
    Abstract: A method of cutting a ring seal, so that the ring seal may be transversely installed over a coaxial element, involves using a cutting tool to cut the seal radially and circumferentially. The cut surfaces overlap in intimate contact and maintain intimate contact to inhibit leakage between the cut surfaces when the ring seal radially expands. The cut surfaces are helicoid, each characterized by a radial generatrix that is constantly perpendicular to the axis of the seal.

  • Helical cut seal
    Patent number: 5087057
    Abstract: A ring seal has a radial cut, so that the ring seal may be transversely installed over a coaxial element. The cut extends radially and circumferentially to provide cut surfaces that overlap in intimate contact and maintain intimate contact to inhibit leakage between the cut surfaces when the ring seal radially expands. The cut surfaces are helicoid, each characterized by a radial generatrix that is constantly perpendicular to the axis of the seal. A method and apparatus are disclosed for making a ring seal having helical cut surfaces.
