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.
