Abstract
Abstract A stubless unit set of multiple plies of the type including at least superimposed top, intermediate and bottom plies is made by removably interconnecting the top and bottom plies together and by removably interconnecting the intermediate and bottom plies together. The top and bottom plies are interconnected by providing a fold flap along an edge of the top ply, applying detachable adhesive to the flap, folding the flap to underlie the bottom ply and contacting the bottom ply with the adhesive, and the intermediate and bottom plies are interconnected by providing at least one hole in the bottom ply and extending a portion of the adhesive through the hole so as to contact the intermediate ply. Each of the plies is devoid of any tear lines which may form a stub.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
236 words
A method of making a stubless unit set of multiple plies of the type which includes superimposed top, intermediate and bottom plies, comprising, providing a fold flap along one edge of said top ply, applying a line of weakening extending along the fold between said flap and said top ply to thereby render said flap removably connected to said top ply, applying a quantity of detachable adhesive to one surface of said flap, providing at least one hole in only said bottom ply along an edge thereof underlying said one edge, folding said flap along said line of weakening and about a edge of said intermediate ply underlying said one edge and further about said edge of said bottom ply, bringing said one surface of said flap into contact with an undersurface of said bottom ply so that said adhesive secures said top and bottom plies together, extending a portion of said adhesive through said hole and against an undersurface of said intermediate ply to thereby interconnect said intermediate and bottom plies together, and maintaining each of said plies free of any tear lines which may form a stub, whereby removal of said top ply along said line of weakening leaves said intermediate and bottom plies intact, or removal of said intermediate ply leaves said top and bottom plies interconnected, or removal of said top and intermediate plies separates each of said plies from one another.
Claim 2
Independent Claim
236 words
A method of making a stubless unit set of multiple plies of the type which includes superimposed top, intermediate and bottom plies, comprising, providing a fold flap along one edge of said top ply, applying a line of weakening extending along the fold between said flap and said top ply to thereby render said flap removably connected to said top ply, applying a quantity of detachable adhesive to one surface of said flap, providing at least one hole in only said bottom ply along an edge thereof underlying said one edge, folding said flap along said line of weakening and about a edge of said intermediate ply underlying said one edge and further about said edge of said bottom ply, bringing said one surface of said flap into contact with an undersurface of said bottom ply so that said adhesive secures said top and bottom plies together, extending a portion of said adhesive through said hole and against an undersurface of said intermediate ply to thereby interconnect said intermediate and bottom plies together, and maintaining each of said plies free of any tear lines which may form a stub, whereby removal of said top ply along said line of weakening leaves said intermediate and bottom plies intact, or removal of said intermediate ply leaves said top and bottom plies interconnected, or removal of said top and intermediate plies separates each of said plies from one another.
Claim 3
Dependent Claim
29 words
The method according to claim 1, wherein said quantity of adhesive is applied to said one surface of said flap along a line parallel to said line of weakening.
Claim 4
Independent Claim
183 words
A method of making a stubless unit set of multiple plies of the type which includes superimposed top, intermediate and bottom plies, comprising, removably interconnecting said top and bottom plies together, and removably interconnecting said intermediate and bottom plies together, said top and bottom plies being interconnected by providing a fold flap along an edge of said top ply, applying detachable adhesive on an inner surface of said flap, folding said flap to underlie said bottom ply and contacting said bottom ply with said adhesive, said intermediate and bottom plies being interconnected by providing at least one hole in only said bottom ply and extending a portion of said adhesive through said hole so as to contact said intermediate ply, and maintaining each of said plies free of any tear lines which may form a stub, whereby removal of said top ply along said line of weakening leaves said intermediate and bottom plies intact, or removal of said intermediate ply leaves said top and bottom plies interconnected, or removal of said top and intermediate plies separates each of said plies from one another.
Claim 5
Independent Claim
183 words
A method of making a stubless unit set of multiple plies of the type which includes superimposed top, intermediate and bottom plies, comprising, removably interconnecting said top and bottom plies together, and removably interconnecting said intermediate and bottom plies together, said top and bottom plies being interconnected by providing a fold flap along an edge of said top ply, applying detachable adhesive on an inner surface of said flap, folding said flap to underlie said bottom ply and contacting said bottom ply with said adhesive, said intermediate and bottom plies being interconnected by providing at least one hole in only said bottom ply and extending a portion of said adhesive through said hole so as to contact said intermediate ply, and maintaining each of said plies free of any tear lines which may form a stub, whereby removal of said top ply along said line of weakening leaves said intermediate and bottom plies intact, or removal of said intermediate ply leaves said top and bottom plies interconnected, or removal of said top and intermediate plies separates each of said plies from one another.
Claim 6
Dependent Claim
31 words
The method according to claim 3, wherein said quantity of adhesive is applied to said inner surface of said flap along a line parallel to an edge of said top ply.
