Abstract:
A method and an apparatus for ablating selected surfaces of an elastomeric product or an attached work piece. A tire is positioned beneath a laser system such that a laser beam is cast upon the tire sidewall or applied work piece. A microprocessor controls the directing of the laser beam and the position of the tire with respect thereto such that various informational and/or decorative designs and configurations may be ablated into the surface impinged by the laser beam. The dwell time of the laser beam upon the surface and other factors control the depth of ablation. In certain embodiments of the invention, a multi layered work piece is employed such that the depth of ablation will correlate to contrasting or complimentary colors or will effect a desired relief appearance.
