5. An improved method of manufacturing a scored rupture disk from a sheet metal section comprising the steps of:
-
clamping said sheet metal section over a central concave-convex dome forming die; cutting said section into a disk while clamped over said die; applying pressurized fluid to the side of said disk opposite said die whereby the central portion of said disk is conformed to said die and formed into a concave-convex dome; and moving a convex score forming blade into forceable contact with the concave side of said concave-convex dome portion of said disk while said disk is clamped over said die and while said pressurized fluid is applied to said dome portion thereof to thereby form scores in said disk. - View Dependent Claims (6, 7, 8, 9)
