Anchoring of the carcass of a tyre.

摘要

A tyre carcass made from a single ply (3) going back and forth from bead to bead is secured in the beads by forming the loop ends into two circumferential alignments (31,32) separated by a rubber layer (8). The anchorage of the carcass is anchored by placing on each side of the bead at least one layer (61,62) of wires oriented circumferentially. A layer of a rubber mixture (5) with a hardness greater than Shore A 70 is interposed between these means and the carcass ply. Tyre carcass prodn. Ensures progressive change of rigidity to flexing of the tyre wall, bead interface, allows anchoring of large number of plies and easy mechanised prodn.
