摘要

A method and apparatus for removing tread material from vehicle tires preparatory to retreading the tire in which a rotary cutter rotating on an axis generally coplanar with the axis of rotation of the tire has sharp cutting elements therein which cut chips from the tread of the tire when the cutter and tire rotate relatively. The sharp cutting elements are formed of a hard wear resistant material such as cemented hard carbides and are detachably supported in a cutter body for ease of replacement therein and also so as to be indexable relative to the cutter body. The cutting elements, or inserts, have a high positive rake angle and the peripheries thereof are inclined at an angle slightly greater than the positive rake angle.
