TIRE BEAD CORE-APEX ASSEMBLY

摘要

TIRE BEAD CORE - APEX ASSEMBLY An apex is cohered to the bead wire bundle or core to form a unitary bead assembly. The core is supported on a rigid continuous planar surface. The apex strip in endless form is supported on the uninflated inflatable cylindrical surface of a turn-up bladder arrangement. Inflation of the bladder arrangement turns or rolls the apex angularly outward to surround the bead core and into an appropriate radial orientation and shape. The bladder action is found to cohere the apex-core so strongly together that conventional roller stitching is not required. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
