Patent ID: 7704346

Claim:
A method of producing a security tag on a body in the form of package, label or other structure on which it is desired to place a security tag: (A) providing a conductor sheet comprising a layer of electrically conductive material in the form of a conductive material web having a top surface and an undersurface; (B) providing a substrate having a top surface, said substrate forming at least a portion of said body; (C) applying an adhesive to said top surface of said substrate in a pattern corresponding to the shape of a desired circuit trace for said tag; (D) disposing said conductor sheet on said substrate so that said undersurface of said conductor sheet is secured to said top surface of said substrate by said patterned adhesive; (E) wherein said conductor sheet has a top surface and an undersurface, and wherein said undersurface of said conductor sheet is secured to a reinforcing sheet, said reinforcing sheet having an undersurface, and wherein said method additionally comprises; (F) securing said undersurface of said reinforcing sheet to said top surface of said substrate by said patterned adhesive; (G) forming said conductor sheet into the shape desired for said electrical trace of said tag by bringing said cutting die into engagement with said conductor sheet and said reinforcing sheet, whereupon said die pierces through said conductor sheet and said reinforcing sheet, but not through said substrate, thereby creating said die cut circuit trace, said circuit trace being surrounded by the portion of said conductive material web and said reinforcing sheet located outside the periphery of said circuit trace, said portion of said conductive material web and said reinforcing sheet located outside the periphery of said circuit trace constituting scrap material; and (H) utilizing a take-up reel to remove said scrap material from said substrate.
