Abstract

An integrated system is provided for folding, inserting, pressure sealing, delivering, and optionally separating into different jobs, mailer type business forms. A common housing mounted by wheels supports in, or on, it: a folder for folding paper sheets with pressure activated adhesive to form to form pre-mailers; an inserter for receipt of pre-mailers from the folder and for placing insert sheets into the pre-mailers; a conventional pressure sealer module for pressure sealing pre-mailers to form mailer type business forms; and a delivery device for delivering stacked forms horizontally out of a bottom portion of the housing. A separator modification of the delivery device may be provided for receipt of sealed mailers to separate the mailers into different stacked groups. Typically the forms move generally downwardly during processing. The inserter includes a pair of reversible vacuum drums which grasp a folded paper sheet and move it apart to receive a substantially linearly driven insert. The separator includes parallel belt conveyor assemblies which can be reciprocated in a horizontal direction perpendicular to a stacking direction.
