Abstract
A pocket containing business form, an intermediate for producing the form, and method of producing the business form, provide optimum securement of the panels of the form together with adhesive by providing the adhesive at and along the side edges rather than merely adjacent the side edges. The form may be produced from a web or sheet by moving it in a first direction, applying adhesive patterns (preferably pressure activated cohesive) to the web or sheet along the first direction adjacent but spaced from first and second side edges and at and along a plurality of centerlines between the side edges, and slitting or cutting the web or sheet along the first direction at the adhesive patterns so that adhesive is provided on both sides of each cut or slit, to provide a plurality of forms (e.g. four forms) with form side edges having adhesive at and along the form side edges. If in a web configuration the web is ultimately formed into a sheet, and the sheet is folded (e.g. eccentrically Z-folded) to form a pocket and the form is sealed in the folded configuration by activating the adhesive.
