摘要 |
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 aluminium, to form a channel-shaped section (5). The section has a flat planar surface portion (6) and a pair of spaced parallel flanges (7) 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 (7) to form lugs (3). A badge is formed in the planar surface portion (6) of the section (5), 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 (3) projecting from the reverse of the badge and formed integrally with the badge by extrusion. |
