METHODS OF MEASURING A SIZE OF EDGE DEFECTS OF GLASS SHEETS USING AN EDGE DEFECT GAUGE AND CORRESPONDING EDGE DEFECT GAUGE

Abstract:

An edge defect gauge that measures a size of edge defects of glass sheets, the edge defect gauge comprising: a body including opposite end edges and opposite side edges that extend between the end edges forming a body, the body having opposite flat faces; and at least one of (i) a dog ear measuring projection extending outward from one of the end edges at one of the side edges, the dog ear measuring projection having a predetermined height and a predetermined length or (ii) a cantilever measuring recess extending inward from the other end edge at the one of the side edges, the cantilever measuring recess having a predetermined height and a predetermined length.
