ABSTRACT:
A system for manufacturing an elastomeric tire utilizing a separate formation of a package having a tire core shape and containing tire belts, plies and beads. The package is formed by a laying up of layers of pre-cure elastomer intradigitated with sections of porous fabric, where the fabric fibers are placed at desired crossing angles to one another, and the pre-cure elastomer layers are positioned therebetween as a sandwich, with the sandwich then cold rolled into the tire core shape. Inelastic hoop shaped beads are fitted to and encapsulated in the tire core side walls ends and, as required, an inelastic belt is fitted around the tire core tread area that is secured thereto as by cold rolling a layer of pre-cure elastomer thereover, completing the tire core package. The tire core package is fitted into a mold, preferably a spin casting mold, and is supported therein equidistant from the mold cavity walls to receive an elastomer sprayed therein as the mold is spun. During spinning, the exothermic heat of reaction of the sprayed elastomer constituents as is generated as they are mixed and sprayed into the mold, completes the cure of the pre-cure elastomer, providing a homogenous finished tire with the belts, plies and beads optimally positioned therein.
