  • Method for recapping tires
    Patent number: 4234370
    Abstract: Apparatus and method for recapping tires, particularly of the type used on off-the-road vehicles. Rubber strips are applied to the prepared tread surface of the tire to "smooth" the tire, after which the tire is disposed on a roller assembly to cut i.e., "groove" a tread design in the tire. The roller assembly is hydraulically displaced to dispose the tire in a pit and is rotated for indexing the tire to groove the circumference thereof. A grooving blade is heated to a controlled temperature and is hydraulically pulled across the tread surface to cut the tread grooves.
