TIRE TREAD GROOVING APPARATUS AND METHOD Abstract of the Disclosure An apparatus and method for grooving tires which is particularly useful for renewing previously used over-the-road tires and which removes a portion of a layer of rubber applied to a tread face of a carcass so as to form on the tread face a predetermined grooved tread design. Relative motion between a heated knife (Ko through K7) and a tire carcass (C) is controlled and coordinated in such a manner as to form a par- ticular selected tread pattern, while one of a plural- ity of knives of varying configurations is selected to form particular portions of the grooved design. As described more fully hereinafter, a programmable memory preferably in the form of a digital, electronic central processor unit controls the operation of components of the apparatus and is programmed to follow particular functional sequences.
