ABSTRACT:
In this continuous form multiple ply envelope assembly each individual envelope is formed by a back ply and a folded top ply. The top ply is secured to a portion of a continuous common web serving as both the back ply for an individual envelope and the means for transporting the assembly through automated business processing equipment. The top ply comprises a central area, two side panels folded inwardly to cover a portion of the central area, a bottom flap folded to overlay both a portion of the side panels and a portion of the central area and lastly a top flap. The top ply is secured to the portion of the continuous web serving as the back ply by lines of adhesive positioned along the side panels, the portion of the bottom flap covering the side panels and along the transverse edge of the bottom flap. A receiving pocket is formed in each envelope between the folded bottom flap and the back ply. The top flap of the top ply of one envelope is disposed within the receiving pocket of the adjacent envelope to hold the top flap flat during processing to avoid jamming of the automated equipment or tearing of the continuous form assembly. The receiving pocket is separate and distinct from the normal material holding area at the interior of the individual envelope.
