ABSTRACT:
An apparatus to effect longitudinal plow folding and subsequent heat sealing of previously computer printed continuous business forms stationary includes a folder and a plurality of elongated heating ribbons disposed parallel to the direction of web travel in spaced apart parallel relationship and being convexly curved for supporting the continuous web passing thereover. Hot melt adhesive applied during manufacture of the stationary is disposed between the plies of the folded-over web, to be locally heated through the web as it lays against, and advances directly over, the multiplicity of parallel heating ribbons. Upon exiting the heater bed, a sandwich platen is provided to maintain the plies in intimate contact, while removing heat from the web and adhesive to bond the plies at each of the multiplicity of spots so heated. The folded and sealed web may then be processed by conventional bursting into individual sealed documents, for mail processing or confidential distribution.
