-6- SCORED METAL SHEET AND METHOD OF FORMING SAME ABSTRACT OF THE DISCLOSURE This relates to the formation of a line of weakening in the form of a score in a metal sheet for defining a line along which the metal sheet may be ruptured. It has been found that when the metal sheet in the area which is to be scored is compressed, the metal sheet may be more easily scored to a controlled residual with a minimum of undue fracture. Accordingly, beads are coined on the underside of the metal sheet on opposite sides of the intended position of the score in a first operation to compress the metal. The then com- pressed metal is engaged by a conventional scoring die on the opposite surface thereof and scoring of the metal is effected in the normal manner.
