Contact adhesive patterns for sheet stock precluding adhesion of facing sheets in storage
First Claim
1. A continuous self-sealing form intermediate comprising:
- a first continuous web of material having parallel side edges and a series of transverse tear lines spaced apart along the web to define a succession of first form units in a folded and stacked configuration;
each of said first form units being of substantially the same size and detachable from the first continuous web along one of said series of tear lines, each of said first form units having a periphery defined by said side edges and said tear lines, and each of said first form units having a first face and a second face opposite said first face, one of said first form units further having a first glue pattern adhered to said first face, said first glue pattern being spaced apart from and parallel to said side edges and said tear lines, said one of said plurality of form units being adjacent to an adjacent form unit having a second glue pattern which is spaced apart from and parallel to the entirety of the periphery of said adjacent form unit;
said first glue pattern being non-registerable with said second glue pattern, whereby upon folding of said one form unit about said tear lines, a first face of said one form unit contacts a first face of said adjacent form unit without adherence between said first and second glue patterns thereon;
a second continuous web of material having parallel side edges and transverse tear lines defining a succession of second form units, one said second form unit having a third glue pattern adhered to a face thereof, said third glue pattern being non-registerable with a fourth glue pattern on an adjacent second form unit; and
,said first and second continuous webs joining together to form a mailer which is sealed by registration of said first glue pattern to said third glue pattern.

Abstract
The present invention provides for the use of contact adhesives to secure separate sheets of multiple ply documents together during the printing and collating process to form finished documents, such as integrated letters and envelopes, billing statements, invoices, etc. The contact adhesive patterns are alternatingly offset or staggered on facing surfaces of adjacent sheets, either in a continuous feed interfolded stack or in a stack of separate sheets. In this manner, the adjacent sheets remain free of one another, as the contact adhesive disposed on each facing surface does not come in contact. Yet, the adhesive pattern on every other sheet is identical, to allow corresponding sheets from another like stack to be glued to those of the first stack. Different staggered adhesive arrays may be provided, to allow the assembly of documents having various numbers of plies therein, and for the forming and assembly of address labels to properly configured envelopes, etc. Like adhesive patterns on alternating sheets may be color coded or otherwise identically marked, to enable the user to assemble the sheets properly. The provision of staggered contact adhesive patterns in non-registry on facing surfaces, with like patterns on alternating surfaces, provides for the use of contact adhesive in the construction of various printed forms and documents. The use of contact adhesive obviates the need for complex and expensive gluing equipment with the printing and folding machinery, which equipment is required with the heat, pressure, and moisture activated adhesives used heretofore.

12. A form intermediate comprising:
-
a plurality of cut-sheet form units present in a stacked configuration, each of said plurality of form units having a first face and a second face opposite said first face, and a periphery defined by parallel side edges and opposite transverse edges, one of said plurality of form units further having a first glue pattern adhered to said first face, said first glue pattern being spaced apart from and parallel to the entirety of the periphery of said one form unit, said one of said plurality of form units being adjacent to an adjacent form unit having a second glue pattern adhered to said second face which is spaced apart from and parallel to the entirety of the periphery of said adjacent form unit; and said first glue pattern on said one of said plurality of form units being non-registerable with said second glue pattern on said adjacent form unit, whereby upon stacking of said plurality of form units, said first face on said one form unit confronting said second face on said adjacent form unit without adherence between said first glue pattern on said one form unit and said second glue pattern on said adjacent form unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
