ABSTRACT:
At least one die pad made of a resilient flowable material is pressed against a metallic plate located on a former with at least one edge projecting beyond an adjacent edge of the former and is turned around the adjacent former edge whilst maintaining the pressure to cause the projecting edge of said plate to conform to the shape of said adjacent former edge and thereby edge-form the metallic plate.
