Abstract:
1. A method for determining a buffing radius for buffing tread from a crown of a tire, the method comprising: receiving a signal from a sensor, the sensor scanning a transverse path across at least a portion of the crown of the tire, the signal being received from each of a plurality of transverse locations across the portion of the tire crown, the signal being generated by the sensor as a function of a distance between the tire crown surface and a belt in the tire; interpreting the sensor signal as a measured distance between the tire crown surface and the belt at each of the plurality of locations; selecting one or more proposed origin positions for a new buffing radius, wherein each of the proposed origin positions are on a centerline of the tire; calculating a projected distance between the crown surface and the belt at each of the plurality of transverse locations across the crown, wherein each projected distance is based upon an arc described by a buffing radius having the one or more proposed origin positions; choosing a new origin position for the new buff radius from the one or more proposed origin positions; and buffing the tread from the tire crown along the arc described by the new buff radius.
