Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 184 words
A business form comprising at least one ply having space thereon for receipt of a stencil assembly, a unitary stencil assembly releasably adhered to said ply over said space and completely removable therefrom, said assembly including two layers adhesively secured together, the first of said layers being a flexible stencil layer immediately adjacent said ply and in contact therewith, the second of said layers being a relatively fiexible frame layer spaced from said ply in the major portion thereof by said first layer, said second layer having a back face in confronting relation to said ply, said second layer back face being totally covered with a pressure sensitive adhesive to cause the same to adhere to said one ply, said frame layer having a cut-out portion affording access to said stencil layer, said frame layer being generally peripherally coextensive with said stencil but having a portion extending beyond the stencil periphery with said portion being directly adhered to said ply, said relatively flexible frame layer having a thickness of the order of said ply to thereby pass unobtrusively around the platen of a typewriter.
