Abstract
A method for applying a plurality of reinforcement belts upon a toroidal tire carcass (50). First and second reinforcement belts (56, 60) are first wrapped around the tire carcass. Then a first belt assembly (68) of a third reinforced belt (69) with elastomeric wedges (72a, 72b) embedded into side edges (70a, 70b) of the third belt is wrapped around the second belt (60) so that the side edges (62a, 62b) of the second belt are spaced from the side edges (70a, 70b) of the third belt. An outer belt (74) and a tread (80) are applied about the third belt, and the tire carcass is ready to be cured in a tire mold.
