ABSTRACT:
The invention is concerned with a method of manufacturing badges and insignia, for example of the type worn by policemen and army personnel. The method comprises extruding metal, preferably aluminum, to form a channel-shaped section. The section has a flat planar surface portion and a pair of spaced parallel flanges projecting rearwardly from the rear face of the surface portion and at right angles to the face. The extruded section is passed through a punching machining machine, and side-acting punches remove portions of the metal forming the flanges to form lugs. A badge is formed in the planar surface portion of the section, and the completed badge is severed from the remainder of the extrusion. The invention also includes a badge made by the method which includes fastening lugs projecting from the reverse of the badge and formed integrally with the badge by extrusion.
