Abstract: The C-fold mailer includes first, second and third panels foldable about transversely extending foldlines to form a mailer with return envelope. Adhesive is applied to one face of the sheet along opposite side margins. The second and third panels are folded and adhesively secured along three margins and the first panel is adhesively secured along the outside face of the third panel. By arranging the lines of adhesive relative to perforated lines along the sides and one end of the mailer, registering sides and end portions of the mailer may be removed while retaining the return envelope adhesively secured along three sides. An integral flap is provided whereby a portion of the first panel may be used as a remittance slip. The slip may be inserted into the return envelope, and the flap folded to seal the return envelope.

Abstract: The form includes a pair of outer panels with an insert therebetween. Corresponding ends of the panels and inserts have registering marginal feed strips. The insert has an additional marginal feed strip extending outwardly of the panels at each of the opposite ends thereof. The insert is formed of heavier material than the panels. The transversely extending edges of the insert are set back from the transverse edges of the panels, the latter being adhesively secured one to the other. Problems in tenting are thus avoided.

Abstract: The business form set includes a plurality of rectilinear sheets forming a multi-ply set including first, second, third and fourth sheets. The first first, second and third sheets are joined one to the other at least along a margin and the fourth sheet is formed of plastic material sealed along three of its four margins to corresponding margins on the backside of the third sheet to form an envelope. The fourth margin of the fourth sheet is inset from the corresponding margin of the third sheet whereby the third sheet margin forms a flap. The first and second sheets are carbonless whereby information printed on the first sheet appears on the second and third sheets. A sample vial may be disposed in the envelope and sealed whereby the vial and information on the third sheet remain one with the other.

Abstract: The mailing system includes an elongated single paper ply folded along spaced parallel longitudinal foldlines to form flaps which overlie an insert disposed between the flaps and a central web portion of the first ply. The flaps terminate short of one another and a second ply of transparent material is adhesively secured between the flaps to provide an address window for the insert. The end margins of the flaps and second ply on the one hand and the central web portion on the other hand are adhesively secured one to the other to seal the mailer. Transverse lines of perforations are provided inset of the end seals to enable the mailer to be opened and the insert extracted.

Abstract: A continuous partially preprinted, preglued form suitable for subsequent envelope construction comprises a single web partially preprinted on one side, having detachable marginal feed hole strips parallel with each longitudinal edge, and transverse marginal lines of perforations defining individual envelope forms with two transverse lines of perforations defining fold lines intermediate the marginal lines. On the side of the web opposite the preprinting, a first transverse adhesive strip is disposed immediately adjacent one of the transverse marginal lines and a second transverse adhesive strip is disposed parallel to the first transverse adhesive strip intermediate between that strip and the adjacent fold line. Two first aligned longitudinal adhesive strips lie parallel to one of the longitudinal edges adjacent a marginal feed hole strip with one adhesive strip extending between the transverse adhesive strips and the other extending between the transverse fold lines.

Abstract: Supply paper is provided at spaced longitudinal positions along one side with a repositionable adhesive. A receptive coating comprised of a CF oil-based ink is applied at spaced longitudinal positions along the opposite of the paper, the positions along opposite sides of the paper being out of registration one with the other. The paper is cut into strips, assembled to form pads with the repositionable adhesive holding the paper strips one to the other at one end thereof. A paper strip may be removed from the pad and flexed to form a band with opposite ends overlying one another with the adhesive in contact with the receptive coating. The repositionable adhesive and receptive coating cooperate to provide enhanced adhesion.

Abstract: Method and apparatus are provided for forming an envelope wherein front and rear panels of an envelope are incorporated in continuous or discrete webs or sheets. Heat activatable adhesive is applied to three peripheral edge portions of one of the envelope panels in facing engagement with the other of the panels. The webs or sheets are fixed together and fed into a printing machine such as a table or desk top laser printer wherein the heat fusing rolls of the printer are utilized to activate the heat activatable adhesive to thereby secure the envelope panels together to form an envelope pocket. One of the envelope panels incorporates a sealing flap portion which may be provided with a rewettable adhesive pattern, while the facing portion of the opposed sheet may be provided with an antistick composition to prevent premature sticking between the sheets in the area of the sealing flap.

Abstract: A continuous business form has a carrier sheet formed of conventional paper (i.e., without a wax or silicone coating) and a forms portion adhered to the carrier sheet by release adhesive (transfer adhesive) adhered to the underside of the forms portion. The forms portion may be peeled from the carrier sheet for application and adherence to another surface while the carrier sheet may be used as paper, for example, for use in impact printing processes.

Abstract: The print head of an electrographic printer is cleaned electrostatically. The printhead has a number of electrodes in an electrode array, which cooperate with a dielectric belt. Periodically, printing with the printer is interrupted (e.g. after every 100 pages of printing, or about every minute), and then substantially all of the electrodes are energized at the same time for a time period sufficient to effect burning off of contaminants from the electrodes (e.g. about the time it takes to print four pages, or about 3 seconds). A host computer controls the operation of the printer components. The printer developer unit may be moved away from the dielectric belt prior to the energization of all of the electrodes to effect cleaning.

Abstract: The multi-ply business form set includes first and second plies having first and second sections separable along a transversely extending line of perforations. The first section has information blocks to comprise an original invoice and a file copy. The second section is divided into two parts, separable each from the other and from the first section. The first part has a card portion which extends transversely a distance less than the width of the form set. The second part includes an envelope formed by gluing the first and second plies one to the other along the margins defining the envelope. The envelope portion extends transversely a distance greater than the card portion but less than the width of the form set. Upon separation of the two parts from the first section and from each other and discarding the stubs of the remaining parts, the card may be disposed in the envelope, for example, for use as a card accompanying a delivery of flowers.

Abstract: Apparatus for processing multisheet or manifold business forms assemblies comprises at least one pair of rotary slitters, a male crimping die or punch associated with one of the slitting blades of the pair for rotation therewith, and a female crimping die or punch receptacle associated with the other of the slitting blades for rotation therewith. Upon rotation of the slitters and their associated crimping dies, the manifold assembly is concurrently slit and crimped to produce locks or paper staples in the body of the assembly. These paper staples effectively hold the various sheets of the assembly in registration or alignment during subsequent processing, but readily permit separation of the various sheets of the assembly when desired.

Abstract: The mailer includes a sheet folded medially to form two plies secured one to another about their marginal edges with an intermediate ply secured about three of its four edges to one of the plies. The remaining edge of the intermediate ply forms an opening for the return envelope defined by the intermediate ply and the one ply. To enable the edge of the return envelope to be slit by automatic mail opening equipment, the intermediate ply is reversely folded along the one edge and adhesively secured to the one ply along the flap. This enables a slit to be formed very close to the edge of the return envelope whereby the return envelope may be opened without interference from the glue line securing the intermediate and one plies one to the other.

Abstract: Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.). Each module has a main process driver which is not directly coupled to a web drive mechanism. Rather, the web drive is program controlled so as to effect the desired web process at controlled displacement intervals along the web. Accordingly, a plurality of successive but different form lengths or depths can be accommodated as the web surface is sequentially processed. A system of such modules can be physically wheeled into position as individual units and electrically connected together by suitable umbilical cords to rapidly configure a desired overall web finishing process. Nevertheless, the entire ensemble of modules performs as though it is a unitary special purpose web processing machine with its various process stations interconnected and synchronized by an electronic "drive shaft".

Abstract: The image receiving surface of a non-impact image printer such as an electrographic printer is treated with an AC corona just prior to image transfer to paper or the like thereby to suppress transfer of non-image background toner and edge effect toner thereby to enhance the transferred image.

Abstract: An endless loop multi layered belt for an electrographic printer is supported on a plurality of rollers and driven by sprocket holes along one belt edge, the belt having coextensive conductive and charge receiving layers. Another embodiment provides a conductive endless strip along the other lateral edge to maintain electrical contact with the conductive layer and a further embodiment provides support for the belt system.

Abstract: A method is practiced to provide an outgoing mailer, parts of which are used to provide a return envelope. A feature of particular interest is that both the face and the back of the return envelope and face of the outgoing envelope are formed from the same web of paper. The article in its outgoing form has a top or face web with a window near its lower right corner, through which a variable address is viewed. A return address may be provided at the upper left corner, and postage at the upper right corner. Under the top face an intermediate web portion exists, which is an extension of the top web folded back nearer its own left edge and doubled against a corresponding segment of the top face. The intermediate web portion is of limited length, so that it does not cover the window. Finally, a bottom web underlies the top face and intermediate web portion, and is of length equal to the top web. The variable address is placed on the bottom web in position to be viewed through the window.

Abstract: A belt conditioner for non-impact electrographic printing apparatus using a flexible dielectric belt (including a conductive member forming a ground plane opposite the dielectric surface) has plural electrically conductive rollers engaging the dielectric charge receiving surface to effect controlled discharge of the surface to a uniform surface electrostatic voltage before direct charge deposition by a print head to form a latent electrostatic image. Corona discharge devices can also be utilized with the rollers to obtain the desired belt conditioning.

Abstract: This invention is concerned with a continuous assembly of self mailer web parts secured together by heat seal adhesive in which a part of the assembly to receive a personal identification number has attached to it a patch of self copy paper with the sensitive coating side of the self copy paper towards the form assembly and other other side of the patch bearing masking printing.

Abstract: In an electrographic printing apparatus, a dielectric belt cleaning system includes counter-rotating pairs of adjoining cylinders mounted to a housing. A vacuum source forces the dielectric belt in free span against the surfaces of the cylinders which are covered by a directional raised nap. Residual toner on the belt is dislodged and drawn through a low pressure zone between each pair of cylinders leading to a filtered discharge outlet. The brushes are cleaned by their interengagement along adjacent cylinder surfaces where the cylinder brushes mesh and also between each cylinder brush and a rake therefor fixed to the housing.

Abstract: A continuous business form assembly provides for computer generated packing slips in adhesive-backed packing envelopes with accompanying packing slip records. A narrow back web with adhesive provides packing slip envelope back panels. A superimposed wide insert web has a non-marginal registry strip inward of a marginal strip, transverse die cuts, and provides product packing slips between snap out perforation lines. A superimposed, narrow front web has a superimposed registry strip, snap perforation lines, and provides packing slip envelope front panels. A narrow adhesive protective web underlies the packing slip envelope back panels, and a wide record web is superimposed on the front web. If desired, feed strips of removed units of the assembly may be left in printer tractors to feed the remainder of the assembly.
