CORRECTION FOR ASYMMETRICAL BUFFING

摘要

Methods, apparatus and computer programs for correcting a buff of tread from a crown of a tire, the steps of the method including measuring the distance between the tire crown surface and the belt at each of the plurality of locations; calculating a projected distance between the crown surface and the belt at each of the plurality of transverse locations across the crown using proposed buff radii, choosing a new position of the buffing radius origin from the one or more proposed origin positions; and buffing the tread from the tire crown along the arc described by the buff radius having the buffing radius origin at the new position.
