Abstract
A method and apparatus for measuring the width of a strip or the widths of multiple strips being conveyed longitudinally through a sensing region of a gauge. The apparatus includes a correction bar that has very highly accurately machined edges and includes a laser point displacement sensor that traverses across the sensing region of the gauge of the invention. The method of the invention uses the correction bar by sensing its edge distance positions and using the data for the sensed edge distance positions and data for its highly accurately known edge distance positions to generate corrections for all distance positions continuously across the entire sensing region. Corrections are then made to sensed edge distance positions of a strip or strips being sensed by the gauge, regardless of the positions of the strip edges.
