  • Device for treading a tire carcass
    Patent number: 6916163
    Abstract: The invention relates to a device for treading a vulcanized tire carcass using an uncured tread comprising a rim (6) for mounting the carcass, an elastic annular mold (7) whose circumferential outer surface is covered with an elastic sleeve (16), the mold being intended to mold the uncured tread (3), the device comprising two disc-shaped elastic flanges (8, 9) intended to cover, respectively, one sidewall of the assembly composed of the constituted tire covered with the mold (7), the larger-diameter peripheral end (82, 92) of each flange (8, 9) bearing a rigid annular member (33) for connection with the sleeve (16) covering the mold (7).

  • Method and apparatus of treading a tire carcass
    Patent number: 6824633
    Abstract: A method and apparatus for treading a tire carcass in which a crude rubber tread is deposited on a tire carcass to be treaded, the tire carcass thus covered having been mounted on a rim and inflated, a resilient ring-shaped mold possessing an inner annular surface ensuring molding of the tread is positioned on the tread, a resilient flange is placed between each bead and each peripheral edge of the mold and covers the outer surface of the tire casing lying between the bead and the edge, and the assembly is placed in a pressurized and heated enclosure.
