Abstract
A laminate composite structure is provided in continuous lengths or rolls for making an unvulcanized carcass for a radial ply pneumatic tire as an intermediate article of manufacture. The laminate has a ply and a plurality of elastomeric components hot formed and attached directly to the ply. Each component has a predetermined cross-sectional profile. The elastomeric components including, but not limited to, a liner, a sidewall, and a chafer. Additional other elastomeric components for the carcass can be formed and attached to the laminate structure. The laminate forms an intermediate article of manufacture that at a later stage of tire building can be cut to length and spliced along common ends to form a cylindrical carcass structure.
