Zusammenfassung: | The present invention relates to pneumatic tires having a laminated innerliner with reinforced splice. The laminated innerliner is a pre-formed laminate comprised of an innerliner film which contains an RFL adhesive coating on both sides for which the innerliner film is cohesively bonded through the RFL adhesive to an uncured tire rubber carcass ply. The uncured splice is comprised of overlapping end portions of the uncured laminated innerliner cohesively bonded together through the RFL adhesive which provides building tack. The uncured splice is reinforced by a an uncured rubber strip cohesively bonded to the laminate by the building tack-providing RFL adhesive for which the strip abridges, the overlapping end portions of the splice, or is sandwiched between the overlapped end portions of the splice, to form a cohesively bonded composite. The assembly, or composite, thereof is cured to adhesively bond the splice and rubber strip together. |
