Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A paper sheet comprising, an attachment marginal edge portion, a recess formed along said attachment edge portion having a predetermined depth, a layer of non-drying, pressure-sensitive adhesive applied only in the recessed marginal edge portion, a protective strip removably applied to the layer of adhesive in said recess, the combined thickness of the adhesive and protective strip being no greater than the depth of the recess so that the thickness of the attachment marginal edge portion of the paper sheet is no thicker than the remaining portion of the sheet to permit processing of the sheet through a conventional processing operation such as printing and copying in a conventional manner.
Claim 2
Dependent Claim
110 words
A paper sheet comprising, an attachment marginal edge portion, a recess formed along said attachment edge portion having a predetermined depth, a layer of non-drying, pressure-sensitive adhesive applied only in the recessed marginal edge portion, a protective strip removably applied to the layer of adhesive in said recess, the combined thickness of the adhesive and protective strip being no greater than the depth of the recess so that the thickness of the attachment marginal edge portion of the paper sheet is no thicker than the remaining portion of the sheet to permit processing of the sheet through a conventional processing operation such as printing and copying in a conventional manner.
Claim 3
Dependent Claim
46 words
The structure set forth in claim 1 wherein the combined thickness of the adhesive and the protective strip is substantially equal to the predetermined depth of the recess to produce a marginal edge thickness substantially equal to the thickness of the remaining portion of the sheet.
Claim 4
Dependent Claim
63 words
The structure set forth in claim 1 wherein the width of the layer of adhesive is less than the width of the recess, and the width of the protective strip is slightly wider than the layer of adhesive to provide an unattached starting flap along the portion of said strip overlying the portion of the recess to which adhesive has not been applied.
Claim 5
Dependent Claim
23 words
The structure as set forth in claim 1 wherein the adhesive is sufficiently aggressive to permanently adhere the sheet to an underlying surface.
Claim 6
Dependent Claim
41 words
The structure shet forth in claim 1 wherein the adhesive is of a type to permit the the sheet to be readily removed from an underlying surface to which it has been adhered and to be reattached to an underlying surface.
Claim 7
Dependent Claim
43 words
The structure set forth in claim 3 wherein the space between the edge of the recess and the adhesive provides a fold line adjacent to the adhesively attached edge which facilitates bending said sheet along said fold line without removal of the adhesive.
