COEXTRUDED SEAMLESS TUBULAR TIRE BODIES FOR USE IN PNEUMATICTIRES

摘要

Coextrusion from rubber of hollow tubular structures with filament reinforcement provides composites which can be formed into spliceless bodies for pneumatic tires. The composites can be formed from one, two, three or more rubber stocks and have portions or layers which can form the body plies, sidewalls, innerliners, stabilizer ply inserts and, optionally, abrasion gum strips of tire bodies. Tires made from the bodies formed from the bodies formed from coextruded composite structures of this invention are seamless and more uniform than those made from convention tire structural components.
