    • 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.
    • 一种用于将插入件同时形成和填充到从纸幅中消隐的信封中的信封的方法和机器,其中所述幅材沿着第一路径间歇地前进,沿预选折叠线刻划并以预先选定的间隔开间隔,以限定未切割的信封 具有底部翼片,封闭翼片和端部翼片的毛坯。 当纸卷沿着第一路径前进时,每个信封坯料的底部折片被折叠以形成一个口袋,前导信封纸坯被停止并且在预选的位置处被记录在一起,并被插入到由底部折片限定的袋中。 带电信封毛坯沿着垂直于第一路径的第二路径前进,其中粘合剂被施加到端部翼片,端部翼片折叠成与底部折翼形成密封关系。 然后,带电信封毛坯沿着垂直于第二路径的第三路径前进,其中粘合剂被施加到封闭翼片,并且封闭翼片折叠成与底部和端部瓣片的密封关系。
