ABSTRACT:
A method and apparatus for tire uniformity correction. During a sensing phase, the tire to be corrected is rotated at a speed higher than the industry standard of 60 revolutions per minute while sensing the force variations to be removed. During a rubber removal phase, the tire is rotated at a slower speed tire while removing rubber in selected amounts from selected areas of the tire corresponding force variations. Frequency modified electrical signals are generated in response to the sensed force variations in the tire during the sensing phase, such signals being at frequencies higher than the industry standard of 60 cycles per minute. Such frequency modified signals are then filtered in summer amplifiers, processed and stored in a microprocessor and then utilized for the removal of rubber in a programmed manner.
