Abstract
A tire buffing apparatus for a tire casing having a plurality of steel belts arranged therein is provided. The tire buffing apparatus including a hub assembly for supporting and rotating a tire casing and a rasp assembly including a rotatable rasp for buffing a tire casing. A tire belt detection system is provided that includes an induction coil element and a sensor. The induction coil element is configured and arranged in relation to the hub assembly such that when the induction coil element is connected to an AC power source, the induction coil element induces a current in the steel belts of a tire casing supported on the hub assembly. The sensor is configured to produce a signal when the rotating rasp is subject to a voltage. A control unit is configured to direct the rasp assembly to stop buffing a tire casing when the sensor produces the signal.
