Abstract
A method of scoring and a scoring tool which enables the scoring of laminated metallic container walls with a wide range of scoring indenter working face widths and which also enables the scoring of conventional and non-repair coated metallic container ends to thin residuals with a narrow, typically about 0.001 inch working face width, indenter. The method essentially consists of applying a compressive force between the principal score line and the wall periphery such that the force is closely spaced to and substantially coextensive with the score. This compressive force may conveniently be applied by a second scoring indenter having a lesser penetration depth than the primary score indenter. The scored container wall produced by the above described method of scoring and the scoring tool.
