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.
A method of manufacturing a badge which comprises extruding metal to form an extrusion having a surface portion and at least one flange portion extending rearwardly therefrom, removing a portion of the metal of the flange portion to form a fastening lug integral with and projecting from the surface portion, and forming a badge in the surface portion.
A method of manufacturing a badge which comprises extruding metal to form a substantially channel-shaped section, said section comprising a planar surface portion having a front face and a rear face, and a pair of spaced parallel flanges projecting rearwardly from the rear face of the surface portion and at right angles thereto, removing a portion of the metal of the flanges to form lugs, forming a badge in the planar surface portion, and severing the badge which has a pair of lugs formed integrally therewith, from the remainder of the extrusion.
A method of manufacturing a badge which comprises taking a metal extrusion in the form of a channel-shaped section having a flat planar surface portion and parallel flanges projecting rearwardly from the flat planar surface portion and at right-angles thereto, feeding the extrusion through a punching machine which removes a portion of the metal of the flanges to form oppositely arranged lugs integral with and projecting from the flat surface portion, forming a badge in the flat planar surface portion of the extrusion and severing the badge with a pair of lugs formed integrally therewith from the remainder of the extrusion.
