Patent number: 4391853Abstract: The disclosed adhesive products include a carrier sheet bearing a polymeric film and an adhesive layer, overlying the film as in dry transfers or underlying the film in products such as wire markers and other labels, or there may be adhesive layers both over and underneath the polymeric film. A constituent initially contained in the polymeric film layer migrates into an ordinarily non-tacky precursor of the adhesive layer, thereby rendering the precursor tacky. The precursor layer becomes adhesive only where it is opposite the polymeric film, being non-tacky outside the area of the film. In important applications, the common area of film and adhesive layers does not cover the whole carrier sheet. Both the adhesive precursor layer and the polymeric film may include portions extending outside the common area.Type: GrantFiled: December 10, 1979Date of Patent: July 5, 1983Assignee: The Datak CorporationInventor: David W.

Patent number: 4243709Abstract: Disclosed is a method for making camouflage from sheets of multi-colored coated fabric. The coated fabric is formed by sandwiching the base fabric between two films of fused polyvinyl chloride film; the two films are tightly bonded to the base fabric. Each film is formed by applying the different - colored plastisols to preselected portions of a carrier web, and then overcoating these colored portions of the web and any uncoated portions of the web with a plastisol of another color. After each of the two multi-colored films is created, they are bonded to the base fabric while the films are still attached to the carrier web; then each carrier web is stripped from the outsides of the finished multi-colored, coated fabric. These multi-colored coated fabrics are cut into sheets which are attached to a net to make the camouflage screen.Type: GrantFiled: June 30, 1978Date of Patent: January 6, 1981Assignee: Brunswick CorporationInventor: Kenneth I.
