Tire preparation for adhesive using laser ablation system and method
A system for preparing an interior surface of a tire for an adhesive includes a turntable configured to remove a layer of material from the tire, and a manipulator operable to move and rotate the tire. The turntable includes a platform rotatable about a first axis. An ablation module is disposed within the platform and includes one or more lasers each configured to emit a laser beam for removing the layer of material from the tire. A plurality of guide rollers extend from the platform and are operable between a retracted position and an extended position to selectively secure the tire to the platform. An exhaust system is disposed adjacent to the one or more lasers.
