Abstract: A continuous form multiple ply ticket assembly wherein the plies interior of the top and bottom plies are captured in at least one control margin and are shorter in each ticket panel than the corresponding top and bottom ply ticket panels to provide a fold space, and at least one line of weakness in the top and bottom plies in the fold space extending transversely of each ticket panel generally aligned with one of the transverse edges of the assembly of interior plies.

Abstract: Oil-containing microcapsules are produced by emulsifying an oily solution of isocyanatoamidine products into an aqueous solution of emulsifier to form oil-in-water emulsion. The reactive isocyanatoamidine products are subsequently hydrolyzed into an impermeable capsule wall.

Abstract: A method and form suitable for airline ticketing wherein interior plies are transversely cut while the exterior plies are only weakened so that advantageously handleable ticket assembly is readily developed by removing the top ply and a portion of the bottom ply to yield a ticket packet.

Abstract: A method of producing a form suitable for airline ticketing wherein interior plies are transversely cut while the exterior plies are only weakened, the cutting of the interior plies occurring before the second exterior ply is united to the remainder of the form.

Abstract: A method of desensitizing carbonless paper by subjecting N-vinyl pyrrolidone and a free radical copolymerizable compound having at least one terminal ethylenic group per molecule in situ to ultra violet radiation.

Abstract: A form suitable for airline ticketing which includes as one exterior ply a web wider than intermediate plies and wherein the overlapping portion is equipped with control openings.

Abstract: A method of producing a form suitable for airline ticketing which includes as one exterior ply a web wider than intermediate plies and wherein the overlapping portion is equipped with control openings.

Abstract: A method of making continuous envelope structure wherein a continuous ply ultimately constituting the backs of a series of envelopes has united thereto a plurality of ply segments, each ply segment ultimately constituting the front and flap of an envelope in the series, and wherein at least a major portion of the flap of each ply segment overlies the front of an adjacent ply segment, and wherein each ply segment and the continuous ply are transversely perforated after assembly.

Abstract: A series of connected, stuffed sealed envelope assemblies, i.e., "mailers" and method of making wherein the insert plies are each rectangular and along one edge thereof having an integral attaching portion which is secured to either the envelope front or back at a location inward of the adjacent control margin.

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.

Abstract: A return envelope for a mailer and method wherein the return envelope has a flap united with the envelope front along a fold line and is equipped with an adhesive adjacent its free edge, the flap initially being positioned in face to face relation with the envelope front, the flap, after removal of the envelope from the mailer being foldable along a line of potential folding intermediate the original fold line and the free edge to create an envelope pocket capable of receiving a check or the like which is larger than the pocket normally developed by the cooperation of the envelope front and back.

Abstract: This improved sealed envelope assembly with locking pockets for free insert material comprises an envelope with front and back plies and at least one insert ply therebetween. The envelope has internal securing means such as adhesive lines adjacent the peripheral edges of the front and back plies for uniting the same, the securing means being spaced from the periphery of the insert ply so that the insert ply lies wholly within the enclosure bounded by the securing means. The back ply has a plurality of spaced embossments located inwardly of the securing means and adjacent the periphery of the insert ply, preferably on at least two sides, each of the embossments comprising a tab having a base portion preferably integrally secured to the back ply along a substantially straight deflection line and a free portion deflected towards the front ply in substantial overlapping relationship with the insert ply so as to form, in conjunction with the back ply, a locking pocket for the insert ply.

Abstract: A method of making a mail piece construction including a series of interconnected envelope assemblies wherein each assembly includes a panel, the major portion of which constitutes the envelope front and flap and wherein a smaller discrete back is secured on three sides to the envelope front to provide a removable strip whereby the assembly is useful as a return envelope.
