  • Method for cementless building of retreaded tires
    Patent number: 5755904
    Abstract: An Apparatus for applying cushion gum to a periphery of a tire casing without cement includes a conveyor having a forward roller near the tire casing. The conveyor is mounted on a carriage that is movable relative to its base so that the conveyor can be moved to contact the tire casing. The conveyor moves the cushion gum below an infrared heater to heat an interface side of the cushion gum to increase its tack and then moves the heated cushion gum between the forward roller and the tire casing. The forward roller of the conveyor applies the cushion gum to the periphery of the tire as the cushion gum exits the conveyor and first contacts the tire casing. A supply roller is provided to move the cushion gum from a supply roll to the rear end of the conveyor. A cutting mechanism is provided between the supply roller and the conveyor to selectively cut the cushion gum.
