Abstract

A mass-production technique for fabricating individual indicia-bearing display sign plaques (10) employs fabricating sheets of large plaque stock (36) as a laminate of a stiffening substrate (12) and an indicia-bearing front sheet (22) adheringly affixed thereto, the indicia (24) on the front sheet bearing the indicia of the desired plaque replicated thereon preferably as a large rectangular array of elements having common boundaries subsequently to be severed along severance lines (38). For wall-mounting of finished plaques adhesive tape strip stock (40) is affixed to lie generally centered on the common boundaries of the array elements, as well as around the periphery of the laminate stock. An edge-registered stack (41) of laminates 41 is then cut along the severing lines by repeated passes of a guillotine-type blade 42. The material forming the substrate and all layers emplaced thereon is chosen to yield clean shearing under such a blade, with the result that the individual plaques 10 when separated have clean sharp edge faces with the peripheral adhesive tape precisely edge-registered thereto. Hot-forming of finished plaques allows them to be configured into self-supporting structures
