ABSTRACT OF THE DISCLOSURE A continuous paper web is fed in a longitudinal path. Glue is applied in transverse strips at regular in- tervals along the longitudinally disposed continuous web over a part only of the width of the web. A first plow folds over a portion of the web having the transverse glue strips to a position above an adjacent flat portion of the web. An insert or stuffer is fed into the web between the folded over portion and the flat portion and against an inner crotch thereof formed by the fold line. The space between the folded over portion and the flat portion away from the fold is open and forms a wide mouth to readily re- ceive the inserts delivered thereto. This first folded over portion is then closed down over the inserts lying on the flat portion causing the glue strips to seal onto the flat portion. The folded over portion and the flat portion of the web contain inserts between each of the transverse glue strips. A glue strip is applied longitudinally to the web on the flat portion thereof not having a folded over por- tion thereabove. A second plow acts to fold the longitu- dinally glued flap strip over onto the top of the folded over portion to thereby seal the top of the formed envelope. The continuous web is then sheared transversely at each transverse glue strip to thus divide the continuous web into multiple individual stuffed and sealed envelopes.
