Abstract:
A laminate composite structure 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 comprising:a ply, the ply having a width, the ply having unvulcanized rubber reinforced with cords, the cords being oriented at an angle between 65.degree. and 90.degree. relative to the length of the laminate;a plurality of elastomeric components each component having a predetermined cross-sectional profile, each component being formed and at the location where formed, being attached while hot to the ply, the elastomeric components including a liner, the liner having a pair of lateral ends defining the axial width of the liner, the axial width of the liner being narrower than the ply width, a pair of sidewalls, each sidewall having a non-linear contoured profile on one surface, each sidewall being attached to the ply and extending axially outward of the ply, a pair of chafers, one chafer being directly attached to and overlying a portion of the liner, the ply and one sidewall; andthe laminate is adapted to be cut at a latter stage of building the tire to predetermined lengths having common ends, the common ends defining the length of the carcass, the common ends are adapted to be spliced along a substantially flat plane, the plane extending through the article across its axial width and is substantially parallel to the cords of the ply, thereby forming a cylindrical carcass adapted to accept a pair of annular bead cores positioned onto the cylindrical carcass.
