Abstract
An apparatus and method for grooving tires which is particularly useful for renewing previously used off-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 pattern of lugs. Relative motion between a heated knife and a tire carcass is controlled and coordinated in such a manner as to form a particular selected tread pattern, while controlling the number and spacing of the lugs and the curvature, angularity, and depth of the incisions which form the lugs. As described more fully hereinafter, a digital, electronic central processor unit controls the operation of components of the apparatus and may be programed to follow particular functional sequences.
