Abstract: Apparatus for preparing the peripheral surface of a tire casing to receive tread material for recapping or retreading the tire casing. The apparatus has two or more buffing wheels, a first being a rough cutter for removing, say, 90 percent of the old rubber, and one or more others which have finer cutting or grinding means on their surfaces, called "texturizing" wheels and/ or "finishing" wheels to so buff the surface of the casing, or selected parts thereof, that the new tread stock will adhere satisfactorily to the buffed crown and shoulder areas of the casing and also to produce a finer surface finish at the junction of the new tread and the old casing for the sake of good appearance. The apparatus also has a power driven mandrel mechanism or rim upon which the casing is mounted for rotation on its normal axis.
