Abstract

A composite assembly for assembling documents and including a substrate sheet, and adhesive layer, and a release liner disposed over the adhesive layer. To assemble a document, the pages of the document are printed on the substrate sheets, the substrate sheets are ordered and aligned, the release liners are removed by the a portion of the release liner overlaying a removed tab being grasped and pulled to peel the release liners from the adhesive layers, and the pages are bonded together by pressure.

Claims

1. A composite sheet assembly, comprising:

a printable substrate sheet with an upper surface and opposite lower surface, first and second converging edges, a generally linear first line of perforations formed generally parallel to the first edge and a second line of perforations generally parallel to the second edge and extending between the first line of perforations and the first edge, a removable tab bounded by the first and second lines of perforations and the first and second edges, the substrate sheet having a marginal first portion of reduced thickness disposed generally inboard and adjacent the first line of perforations the reduced thickness first portion is located on the upper surface of the sheet;

an adhesive layer is adhered on the lower surface of the reduced thickness first portion of the substrate sheet and is disposed inboard and proximate the first line of perforations, a remaining second portion of the substrate sheet free of the adhesive layer; and

a release liner releasably disposed over the adhesive layer and further including a portion that overlies the tab.

2. The composite assembly of claim 1, in which the tab is generally rectangular.

3. The composite assembly of claim 1, in which the tab is generally square.

4. The composite assembly of claim 1, the substrate sheet comprising a material selected from bond, clay-coated paper, polymeric material and carbonless paper.

5. The composite assembly of claim 1, the adhesive layer comprising an adhesive selected from low-peel, pressure-sensitive adhesive and high-peel, pressure-sensitive adhesive.

6. The composite assembly of claim 1, the release liner comprising a silicone.

7. The composite assembly of claim 1, the release liner comprising a material selected from a silicone, an acrylate, a urethane, a polyolefin, and a polyvinyl carbamate.
