ABSTRACT:
Business forms are sealed by pressure with reduced tenting and pillowing. Each form has a strip of pressure sensitive adhesive of a predetermined width. In an automatic continuous, sequential manner, upper and lower rollers operatively biased together by spring pressure activate the pressure sensitive adhesive to affix one part of the form to another. The force applied by the rollers is applied only to the approximate area of the predetermined width of the adhesive, not over the whole form. Conveyor tapes are associated with the rollers to facilitate conveyance of the forms, and a pressure of about 120 lbs. per lineal inch is applied to the pressure sensitive adhesive. A buckle or insert folder can be used to fold the forms, and they are then fed to a first pressure sealing module. A 90.degree. transfer conveyor conveys the forms from the first pressure sealing module to a second module, and from the second module they are removed by a discharge conveyor.
