  • Patent number: 4861636
    Abstract: Laminates are taught which are useful as feedstocks in microprocessor-controlled, electromechanical drawing devices. The type of feedstock laminates disclosed comprise a carrier substrate whose upper surface has been coated with a pressure sensitive adhesive, and masked with a protective cover. The protective cover is subdivided into panel strips which can be removed to expose the substrate's adhesive layer. Any desired pattern material can then be cohered to the adhesive, and a desired design insised therein with the electromechanical drawing device. Thereafter, the design is removed from the substrate and used for the purpose for which it was intended.
