Abstract

A multi page mailer type business form is constructed by applying a first adhesive pattern to the top sheet bottom face perimeter areas, a second adhesive pattern to the bottom sheet top face perimeter areas, and applying third and fourth adhesive patterns to the middle sheet top and bottom face perimeter areas respectively. Variable information is printed on the top, bottom and middle sheets including machine readable identification information (bar code) which is common to the sheets that are to be assembled into a final multi page mailer. The set is accumulated, and verified by scanning the identification information, and then the perimeter adhesive patterns are sealed. The adhesive is preferably pressure sensitive adhesive, and the final mailer produced has a book-like construction. The adhesive patterns are such that the top and bottom sheets can be provided in a stack without the perimeter adhesive patterns aligning, and the middle sheets can be provided in a separate stack. A four-part (or more) form may be constructed by slitting two sheets with adhesive patterns into four.

Dependent claims

A method of forming a multi page mailer type business form having a plurality of parts, including top, bottom, and at least one middle, sheets, each sheet having top and bottom faces, a quadrate shape with four edges, and perimeter areas adjacent the edges, said method comprising the steps of:

(a) applying a first adhesive pattern to said top sheet bottom face perimeter areas;
(b) applying a second adhesive pattern to said bottom sheet top face perimeter areas;
(c) applying a third adhesive pattern to said middle sheet top face perimeter areas, and a fourth adhesive pattern to said middle sheet bottom face perimeter areas;
(d) printing variable information on the top, bottom, and middle sheets, including machine readable identification information which is common to top, bottom, and middle sheets that are to be assembled into a final multi page mailer;
(e) verifying that the collated and accumulated set contains matching sheets by scanning the identification information on sheets of that collated set;
(f) collating and accumulating a set containing a top, bottom, and middle sheet;
and
(g) effecting sealing of the perimeter adhesive patterns of the sheets of the collated set so that a multi page mailer type business form is produced.
