Abstract
A method of measuring camber in a sheet of metallic material comprises the steps of displacing the sheet between fixed guides in a plane perpendicular to the width of the sheet such that a point on a center of the sheet travels a predetermined distance, measuring the length of the sheet adjacent a first longitudinal edge thereof which moves past a datum line when the sheet is displaced the predetermined distance and generating a signal having a value A proportional to the length, measuring a length of the sheet adjacent to a second, opposite longitudinal edge which moves past the datum line when the sheet is displaced the predetermined distance and generating a signal having a value B proportional to the second edge length, and calculating camber at the first edge, expressed as a radius of curvature R.sub.C of the sheet, by the equation: ##EQU1## where W equals the width of the sheet.
