Continuous business assembly of combined mailers and top-opening return envelopes

Claim 1

A continuous business form assembly providing combined mailers and top-opening return envelopes, and comprising: a first web being continuous in a longitudinal direction: having a transverse first web width in a direction perpendicular to the longitudinal direction between opposed, longitudinally extending,continuous first and second margins: a central longitudinally extending continuous fold line a first longitudinally extending,continuous marginal feed strip including a longitudinally extending, continuous first series of pin feed holes and a longitudinally extending,continuous first marginal line of perforations: a second longitudinally extending, continuous marginal feed strip including a longitudinally extending,continuous second series of pin feed holes and a longitudinally extending, continuous secnnd marginal line of perforations a continuous series of longitudinally spaced, transversely extending,form-defining,third lines of perforations: a continuous series of longitudinally spaced,transversely extending,strip defining pairs of fourth lines of perforations: a continuous series of longitudinally spaced,transversely extending,envelope flap'defining,fifth lines of perforations: a continuous of separable business form sheets with each sheet being defined between two adjacent lines of the form-definingthird lines of perforations and each sheet including opposed, first tear strips defined between the first,second,third and fourth lines of perforations: a message panel defined between the opposed tear strips,the first line of perforations and the central fold line: a first envelope panel defined between the second, fourth and fifth line of perforations and the central fold line: and an envelope flap portion defined between the first envelope panel, one of the tear strips, the second perforation line and the central fold line. a second web being continuous in the longitudinal direction, and having a transverse second web width not greater than the transverse distance between the central fold line and the second marginal feed strip: the second web being superimposed over the first web between the central fold line and the second marginal feed strip: and the second web having a longitudinally extending,continuous margin adjacent the central fold line,perforation lines overlying portions of the third,fourth and fifth perforation lines: second envelope panels, tear strips and flap portions overlying the first envelope panels,tear strips and flap portions,respectively, of the first web: first adhesive means for adhering the second web to the first web for forming top-opening, scalable return envelopes of the first and second envelope panels and flap portions and second adhesive means for adhering the message panels of the forms to the second web while the first web is folded about the central fold line for forming mailers including the return envelopes: whereby the mailers may be transmitted, the feed and tear strips removed, the message panels and envelopes separated, the return envelopes sealed and returned, and the return envelopes slip in automatic slitters.
