ABSTRACT:
A method of and a machine for the simultaneous forming of and stuffing of an insert into an envelope blanked from a paper web wherein the web is intermittently advanced along a first path, scored along preselected fold lines and notched at preselected spaced intervals for defining unsevered envelope blanks having a bottom flap, a closure flap and end flaps. The bottom flap of each envelope blank is folded as the web advances along the first path to form a pocket, the leading envelope blank is stopped and registered at a preselected position, severed and charged with an insert into the pocket defined by the bottom flap. The charged envelope blank is advanced along a second path perpendicular to the first path, where adhesive is applied to the end flaps, the end flaps folded into sealing relationship with the bottom flap. The charged envelope blank is then advanced along a third path perpendicular to the second path where adhesive is applied to the closure flap and the closure flap folded into sealed relationship with the bottom and end flaps.
