Abstract

1304029 Making cartridge primer casings DYNAMIT NOBEL AG 1 June 1970 [25 June 1969] 26383/70 Heading B3A [Also in Divisions C7 and F3] A method of forming a casing for a cartridge primer by progressive deformation of a strip of steel, comprises forming a cylindrical casing 1 with a flat base 2, indenting the base and drawing an anvil, pointing the anvil and simultaneously reducing the external diameter of the casing, stamping out kidney-shaped holes 6, and cutting out the finished casing. A high-speed steel or hard metal multiple sequential tool is used for the drawing which is effected step-bystep at a speed that wholly or substantially avoids stretch-ageing. In another method the anvil is produced by impact extrusion. The steel strip may be copper coated or " Bonderised " (Registered Trade Mark). The composition and properties of the steel are specified.
