  • Patent number: 4284450
    Abstract: Repairing of tubeless tires and tubeless covers includes injecting a suitable cement through the puncture hole onto the inner surface of the tire, this injection taking place in two successive steps. A first step involves depositing an annular patch of cement around the hole, and in a second step a pearl of cement is deposited concentrically to the hole. The pearl spreads on the annular patch to form a relatively wide deposit centered on the puncture hole and having a thickness sufficient to constitute, after drying and setting, a real repair patch centered on the puncture.
    Type: Grant
    Filed: December 11, 1979
    Date of Patent: August 18, 1981
