Retread tire buffing with multiple response curves
First Claim
1. A method of buffing tread from a tire carcass, the method comprising the steps of:
- positioning a sensor at a first lateral location along a width of the tread;
receiving a first signal response from the sensor, the first signal response generated as a function of a distance between the sensor and a belt in the tire and a tire characteristic;
selecting a first signal response curve from a plurality of signal response curves based upon the first lateral location of the sensor, the selected signal response curve representing the function of the distance between the sensor and the tire belt and the tire characteristic;
determining from the first signal response curve the distance between the sensor and the belt for the signal response received;
buffing tread from the tire across a first portion of the tread width until the distance between the sensor and the belt reaches a final distance;
positioning a sensor at a second lateral location along a width of the tread;
receiving a second signal response from the sensor at the second lateral location, the second signal response generated as a function of a distance between the sensor and a belt in the tire and a tire characteristic;
selecting a second signal response curve from a plurality of curves based upon the second lateral location of the sensor along the width of the tread, the second signal response curve representing the function of the distance between the sensor and the tire belt and the tire characteristic, where the second signal response curve is different than the signal response curve selected in the prior step of selecting;
determining from the second signal response curve the distance between the sensor and the belt for the signal response received; and
,buffing tread from the tire across a second portion of the tread width until the distance between the sensor and the belt reaches a final distance.

Abstract
A method and apparatus for buffing tread from a tire carcass, the method comprising the steps of: positioning a sensor at a first lateral location along a width of the tread; receiving a first signal from the sensor, the first signal generated as a function of a distance between the sensor and a belt in the tire and a tire characteristic; selecting a first signal response curve from a plurality of signal response curves based upon the first lateral location of the sensor, the selected signal response curve representing the function of the distance between the sensor and the tire belt and the tire characteristic; determining from the response curve the distance between the sensor and the belt for the signal response received; buffing tread from the tire until the distance between the sensor and the belt reaches a final distance. The steps are repeated at a second lateral location.
