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 of 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 stock. A four-part (or more) form may be constructed by slitting two sheets with adhesive patterns into four.
