Abstract:
A method and apparatus for producing long flat metal strip from a coiled metal strip so that the flat metal strip has uniform straight edges to a high degree of precision. The uncoiled strip is straightened by traction to a degree slightly beyond its elastic limit, laid flat unclamped on a bench, then immobilized on the bench and the edges trimmed by mobile shears movable on a longitudinal guide member lying parallel to the axis of the bench and the metal strip thereon.
