Envelope assembly

Claim 1

An assembly including a series of envelopes having superimposed plies defining tops and bottoms of individual outer envelopes, insert materials lying between said plies, said individual outer envelopes being delimited by perforation lines facilitating separation of said individual envelopes, means secured to said insert materials for accurately aligning said insert materials within said individual envelopes between said plies, means sealing the superimposed plies of said outer envelopes about a substantial portion of the periphery of said plies, said plies being unsealed only at and immediately adjacent said aligning means on said insert materials so that said insert materials are wholly unsecured to said outer envelope, the periphery of said insert materials being spaced inwardly from the periphery of said plies except at said aligning means, at least a portion of said aligning means on said materials extending to the periphery of said plies, said aligning means on said insert material including control punching secured at spaced points to said insert material, said control punching comprising a strip having equally spaced openings therealong, said plies having control means thereon comprising a plurality of equally spaced openings, the openings in said control punching on said insert material being aligned with the openings in said control means on said plies, the distance from the openings in the control punching removably secured to said insert materials to the free edge of the control punching is substantially less than the distance from the openings in the control means on said plies to the closest substantially parallel sealed edge of said outer envelope to thereby permit said insert materials to be free from securement to said outer envelope, and means for separating said aligning means and said insert materials upon removal of said insert materials from said outer envelope.
