Patent ID: 6974519

Claim:
A process for encapsulating a package of plies and beads with, as required, a belt or belts within an elastomeric tire as a tire core package in a tire casting process comprising, with a pre-cure elastomer having a stiffness that allows it to be rolled into and hold a curved shape that will cure when subjected to a heat of reaction provided by a mixing of elastomeric materials in a spin casting process, forming said pre-cure elastomer into thin flat sections; intradigitating layers of said pre-cure elastomer sections with sections of fabric material that have been laid up such that the material fibers are at desired crossing angles to each other, forming a sandwich of alternating layers of pre-cure elastomer and sections of fabric as a plies; cold rolling said sandwich into a tire core shape with ends of said sandwich each folded around, to encapsulate each inelastic beads; filling and supporting said tire core package in a mold with said tire core package side walls equidistant from opposing walls of said mold; and mixing and injecting a liquid elastomeric material into said mold that is spinning, with a heat of reaction generated by mixing of constituents of said elastomeric material curing said pre-cure elastomer providing bonding to said plies and beads and with the injected elastomeric material.
