Method and apparatus for recapping a tire with a flexible segmented mold

摘要

A method and apparatus for retreading a tire includes a mold segment (14) having open ends (16) and (18). A tire carcass (10) has a layer of uncured rubber (12) built up on the surface thereof. The mold (14) is disposed therearound with ribs (20) resting on the surface thereof. A semi-flexible cap (24) is disposed over the ends (16) and (18) which are separated by a gap (20). An elastic strap (26) is then wrapped about the assembly to secure the mold (14) to the built up tire carcass (10). An envelope (28) is then wrapped about the assembled tire carcass (10) to provide a radially inward force thereto. The whole assembly is then cured in a curing oven.
