Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
The method of manufacturing a pad of connected paper sheets including a plurality of sheets, each having a recess formed along one marginal edge portion thereof, applying a reusable layer of pressure-sensitive adhesive in the recess, covering the pressure-sensitive adhesive layer with an attachment strip, the combined thickness of the adhesive and the attachment strip being no greater than the depth of the recess, forming a separation slit in each sheet through overlying relation to the adhesive layer and the attachment strip but of insufficient depth to sever the attachment strip, to thus divide the sheet into two segments, an attachment segment and a removable segment, and connecting the attachment portions and the respective attachment strips together to form a pad of a plurality of said sheet assemblies.
Claim 2
Independent Claim
128 words
The method of manufacturing a pad of connected paper sheets including a plurality of sheets, each having a recess formed along one marginal edge portion thereof, applying a reusable layer of pressure-sensitive adhesive in the recess, covering the pressure-sensitive adhesive layer with an attachment strip, the combined thickness of the adhesive and the attachment strip being no greater than the depth of the recess, forming a separation slit in each sheet through overlying relation to the adhesive layer and the attachment strip but of insufficient depth to sever the attachment strip, to thus divide the sheet into two segments, an attachment segment and a removable segment, and connecting the attachment portions and the respective attachment strips together to form a pad of a plurality of said sheet assemblies.
Claim 3
Dependent Claim
149 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, and a separation slit through the paper sheet in overlying relation to an intermediate portion of said protective strip to divide the paper sheet into an attachment segment and a separate removable segment connected only by the protective strip.
Claim 4
Dependent Claim
149 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, and a separation slit through the paper sheet in overlying relation to an intermediate portion of said protective strip to divide the paper sheet into an attachment segment and a separate removable segment connected only by the protective strip.
Claim 5
Dependent Claim
53 words
A plurality of sheets having the structure set forth in claim 2 positively connected together along the attachment segment of each sheet to permit removal of the removable segment by removing the same from the portion of the attachment strip overlying the adhesive surface and thus separating the two segments of the sheet.
