  • Method and apparatus for treading tires
    Patent number: 4178198
    Abstract: A method of applying a tread band to a tire carcass includes the steps of placing a pre-vulcanized tread band on the inner surface of a resiliently flexible tread band holder and deforming the band holder inwardly to contact the tread band with a tire carcass. The deformation is carried out using inflatable air bags on the outer surface of the tread band holder. The deformation shortens the periphery of the tread band and produces a compressive stress in the band, which is retained in the band after bonding to the tire carcass.
