DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference is now made to FIG. 1, which is a simplified schematic illustration of a system providing real-time, integrated production of envelopes and the contents thereof in accordance with a preferred embodiment of the present invention. The system of FIG. 1 preferably comprises at least one production facility 100 for the production of individually addressed sealed envelopes containing personalized printed material matched to individual addresses.

Preferably, the production facilities 100 may be geographically distributed so as to be adjacent to bulk mail drop-off locations of postal authorities or delivery contractors. It is appreciated that such locations may be in different countries or in different regions of a single country. The postal authorities or delivery contractors at different ones of such locations may require different franking. It is a particular feature of the present invention that due to the real-time operation of the system, a given production facility 100 may be selected at a given time in order to take advantage of beneficial spot pricing of bulk mail delivery services by a postal authority or delivery contractor.

Each production facility 100 preferably includes at least one high speed digital printer 101, such as, for example, a IBM infoprint 2105ES, commercially available from IBM Corporation of Armonk, N.Y., a Konica Minolta Bizhub Pro 1050P, commercially available from Konica Minolta Holdings Inc. of Tokyo, Japan, or a Ricoh DDP184, commercially available from Ricoh Corporation of Tokyo, Japan, which is capable of printing on a substrate, such as paper on one or more white rolls 102. Alternatively, the paper may be provided to printer 101 as cut sheets, fan-fold stacks or in any other suitable form, and may be of any suitable color, thickness or width. Each digital printer 101 preferably receives printing instructions from at least one printing controller 110, which, in turn, receives personalized printing data from one or more data sources 112. The personalized printing data includes envelope addresses and often includes personalized envelope contents which vary and are keyed to specific envelope addresses.

In accordance with a preferred embodiment of the present invention the controller 110 imposes the envelope addresses and other envelope information into the stream of information provided to one or more printers 101, such that the envelope information is printed onto an envelope or into an envelope information sheet to be inserted into a windowed envelope.

It is a particular embodiment of the present invention that the envelope information may be printed onto the envelope or onto the envelope information sheet via a different printing stream than the stream that prints envelope contents pages, or alternatively, that the envelope information and envelope contents pages are printed in a single stream.

It is a particular feature of the present invention that printing controller 110 may receive personalized printing data from multiple disparate sources 112, such as banks, utilities, insurance companies and other customers, each relating to a printing piece which may vary in its dimensions, number of pages of content and other parameters. Preferably, the printing controller 110 commingles the data received from multiple disparate sources 112 and orders the personalized printing data from such multiple disparate sources 112 such that it is printed and thus output in a desired distribution sorting order. The distribution sorting order is preferably selected to maximize savings in postage and may be according to postal code and even more preferably in the delivery order of a mailman's route. Ordering the printing in such an order enables very significant discounts in postage to be realized without requiring downstream sorting. The amount of such discounts may exceed the cost of producing the mailing piece.

Alternatively, printing controller 110 may receive personalized printing data from a single source 112, relating to a printing piece which may vary in its dimensions, number of pages of content and other parameters. In this embodiment, printing controller 110 orders the personalized printing data from the single source 112 such that it is printed and thus output in a desired distribution sorting order. The distribution sorting order is preferably selected to maximize savings in postage and may be according to postal code and even more preferably in the delivery order of a mailman's route. Ordering the printing in such an order enables very significant discounts in postage to be realized without requiring downstream sorting. The amount of such discounts may exceed the cost of producing the mailing piece.

It is also a particular feature of the present invention that multiple digital printers 101 may be located adjacent multiple mailing locations and that a digital printer 101 may be selected according to its propinquity to a bulk mail drop off location, in order to provide additional cost savings in transport. It is appreciated that a printing controller 110 may divide a printing job from a given source 112 into multiple printing jobs to be handled by various digital printers 101, each optimally located nearby a bulk mail drop off location for a given group of addresses.

It is appreciated that the digital printer 101 prints personalized envelope and envelope contents information on one or both sides of the substrate, prior to envelope formation, thus enabling, inter alia, printing on the interior of envelopes. The digital printer 101 may provide a printed output in one or more forms, such as fan-folded stacks 114, cut stacks of sheets 116 and rolls 118. The digital printer 101 may operate asynchronously with respect to the remainder of the system.

Referring additionally now to FIGS. 2A and 2B, which illustrate two alternative embodiments of a cutting and/or envelope/envelope contents differentiation stage forming part of the system of FIG. 1.

As seen in FIGS. 2A, downstream of each digital printer 101 there is preferably provided a cutting and envelope/envelope contents differentiation stage 120 at which printed envelope sheets 122 are cut, preferably according to an envelope blank and preferably by a suitable die cutter 123, and the printed envelope contents are cut into one or more envelope contents sheets 124 and trimmed as necessary by a side trimmer 126. Preferably, a scanning functionality (not shown), identifies pages coming out of the printer as envelope sheets or as envelope contents sheets, and directs them toward the suitable trimming device, such as the die cutter 123 or the side trimmer 126. A preferred scanning functionality is that described in U.S. Pat. No. 5,008,520, the contents of which are hereby incorporated by reference. It is appreciated that any suitable cutting method is suitable, such as laser cutting or water jet cutting.

In the illustrated embodiment of FIG. 2A, envelope sheets 122 are separated from envelope contents sheets 124 prior to die cutting and trimming. Paper scraps are removed preferably by vacuum. Alternatively, the envelope sheets 122 may be joined to the envelope contents sheets 124 as described in U.S. Pat. No. 7,100,348, the disclosure of which is hereby incorporated by reference.

Turning to FIG. 2B, it is seen that downstream of each digital printer 101 there is preferably provided a cutting stage 120. As seen in FIG. 2B, the printed envelope sheets 122 are provided in a first stream, having a first cutting stage 127, at which printed envelope sheets 122 are cut, preferably according to an envelope blank and preferably by suitable die cutter 123, and the printed envelope contents are provided in a second stream having a second cutting stage 128, at which the envelope contents are cut into one or more envelope contents sheets 124 and trimmed as necessary by side trimmer 126. It is appreciated that the envelope sheets and envelope content sheets may be printed and cut out of different substrates, here shown as a fan fold stack of sheets and a roll of sheets, and as substrates of different colors. It is appreciated that any suitable cutting method is suitable, such as laser cutting or water jet cutting.

In the illustrated embodiment of FIG. 2B, paper scraps are removed preferably by vacuum. Alternatively, the envelope sheets 122 may be joined to the envelope contents sheets 124 as described in U.S. Pat. No. 7,100,348, the disclosure of which is hereby incorporated by reference.

It is appreciated that, as seen in FIGS. 2A and 2B, the number of envelope contents sheets 124 may vary from envelope to envelope. All the envelope contents sheet 124 belonging to a specific envelope are preferably accumulated by an accumulator 129, and then continue to move through the system as a group of accumulated envelope contents sheets 124. Envelope contents sheets 124 belonging to a single envelope are preferably identified by a scanning functionality (not shown), preferably that described in U.S. Pat. No. 5,008,520, the contents of which are hereby incorporated by reference. It is further appreciated that the die cutter 123 of stage 120 preferably operates asynchronously from the envelope formation stage which follows.

Alternatively, envelope sheets 122 and envelope content sheets 124 may be produced by any other suitable means and supplied to the envelope formation stage which follows.

Returning to FIG. 1, it is seen that downstream of the cutting and/or envelope/envelope contents differentiation stage 120 is a content containing envelope formation stage 130 at which the envelope 132 is formed by folding the envelope sheet 122 over the envelope contents sheet or sheets 124 and gluing a back flap of the envelope sheet 122 and side flaps of the envelope sheet 122 respectively. At this stage externally produced inserts may be added to the envelope contents. Envelope formation stage 130 is described further hereinbelow with reference to FIGS. 3A, 3B and 4.

In accordance with a preferred embodiment of the present invention, at a bundling stage 140, the finished mailers 142, each including an envelope 132 and its content sheets 124, are gathered and bundled in a desired distribution order for delivery to the postal delivery contractor. A suitable stacking and bundling system is described in U.S. Pat. No. 6,682,067, the disclosure of which is hereby incorporated by reference. It is noted that where multiple printing jobs from disparate sources are preferably combined in a single print run, bundles 150 may contain mailers of differing sizes and configurations, multiple ones of which may be directed to the same addressee from different senders.

Reference is now made additionally to FIGS. 3A and 3B, which illustrate two alternative embodiments of the structure and operation of envelope formation stage 130.

In the embodiment illustrated in FIG. 3A, envelope 132 is formed by transversely scoring envelope sheet 122 and subsequently folding the envelope sheet 122 over the suitably folded envelope contents sheet or sheets 124 and gluing a back flap 155 and side flaps 156, respectively. It is appreciated that at the envelope formation stage 130 an inside flap envelope or an outside flap envelope may be formed, depending on the order in which the back flap 155 and side flaps 156 are glued to each other and on the surface of each of the flaps to which the glue is applied.

As seen in FIG. 3A, suitably die cut envelope sheets 122 are received along a first conveyor 200, back flap 155 facing forwardly, and envelope contents sheets 124, to be enclosed within the envelope to be formed from a corresponding envelope sheet 122, are received along a second conveyor 202 by accumulator 129. The accumulated envelope contents sheets 124 are then folded as desired, typically in half or into three portions, by an envelope contents sheet folder 204, which is typically a buckle shoot folder.

The envelope sheet 122 is preferably transversely scored by a scoring mechanism 205. The folded envelope contents sheets 124 are positioned over a middle panel of the envelope sheet 122, preferably by a suitable positioner, such as a positioner including servo controlled nips (not shown), and released in synchronization with the location of corresponding envelope sheet 122. Alternatively, the envelope contents sheet folder 204 may also function as a positioner for the envelope contents sheets 124. Optionally, one or more inserts 158 may be placed onto the envelope sheet 122 by an insert feeder 208. Preferably, inserts 158 are also positioned by a suitable positioner (not shown), such as a positioner including servo controlled nips.

In accordance with a preferred embodiment of the present invention, envelope sheet 122 and the envelope contents sheets 124 are merged together precisely by the positioner to allow for a high degree of placement precision, regardless of the envelope processing speed. This is preferably achieved by varying the speed of conveyor 202 such that the envelope contents sheets 124 meet the appropriate envelope and are merged together precisely. The positioner also provides a high degree of placement precision independent of the size of the content pages vis-à-vis the envelope size and allows for a varying number of contents sheets 124 to be placed in each envelope.

The envelope sheet 122, having thereon the folded envelope contents sheets 124, and optionally inserts 158, is then folded around content sheets 124 and optional inserts 158 by a suitable folder 210.

Alternatively, as shown in FIG. 3B, envelope 132 is formed by folding the envelope sheet 122 together with the envelope contents sheet or sheets 124 and gluing back flap 155 and side flaps 156, respectively. It is appreciated that at the envelope formation stage 130 an inside flap envelope or an outside flap envelope may be formed, depending on the order in which the back flap 155 and side flaps 156 are glued to each other and on the surface of each of the flaps to which the glue is applied.

Suitably die cut envelope sheets 122 are received along a first conveyor 200, back flap 155 forwardly, and envelope contents sheets 124, to be enclosed within the envelope to be formed from a corresponding envelope sheet 122, are received along a second conveyor 202 by accumulator 129 and released by a positioner 212, including servo controlled nips, in synchronization with the location of corresponding envelope sheet 122. Such synchronization is preferably achieved by varying the speed of conveyor 202 in accordance with the speed of conveyor 200. This synchronization preferably results in precise positioning of the envelope contents sheets 124.

Optionally, one or more inserts 158 may be placed onto the envelope sheet 122 by insert feeder 208. Preferably, inserts 158 are also positioned by a suitable positioner, such as a positioner including servo controlled nips.

Positioner 212 preferably allows for a high degree of placement precision, regardless of the envelope processing speed. The positioner 212 provides a high degree of placement precision independent of the size of the content pages vis-à-vis the envelope size and also allows for a varying number of contents sheets 124 to be placed in each envelope.

The envelope sheet 122 having the envelope contents sheets 124, and optionally inserts 158 thereon, enter buckle chute folder 214, which folds the envelope sheet 122, content sheets 124 and optional inserts 158.

Reference is now made additionally to FIG. 4, which illustrates a sealing stage and a bundling stage forming part of the system of FIG. 1. As seen in FIG. 4, side flaps 156 are scored by a scoring mechanism 216, and glue is then applied to side flaps 156, such as by glue applicator 218. Alternatively, the glue may be applied to the back flap 155. Glue can be applied in the form of hot or cold melt glue, or using any suitable method, including strip application. Side flaps 156 are then folded over contents sheets 124 and envelope sheet 122 by any suitable folding method, such as by using a plow folder. Alternatively, as shown in the embodiment of FIG. 3B, glue is applied to side flaps 156 or to back flap 155 as the last part of the buckle folding process.

In another alternative embodiment, scoring is performed upstream, in either the cutting or the merging modules, glue is applied to back flap 155 or to side flaps 156 in the folder module or in a separate module, and side flaps 156 are folded under the back flap 155 of the envelope sheet 122, yielding an envelope with “inside flaps” or over the back flap 155 of the envelope sheet 122, yielding an envelope with “outside flaps”.

As seen further in FIG. 4, the direction of envelope travel is changed by 90 degrees, a top flap 222 of the envelope sheet 122 is scored by scoring mechanism 230, glue is applied thereto, such as by applicator 232, and top flap 222 is folded over, by any suitable folding method, such as by using a plow folder 234, thus sealing the envelope. Alternatively, glue may be applied to the back flap 155, onto which the top flap 222 is folded. Finished mailers 142 are preferably laying flat while they are scored, glued and sealed to facilitate operation for postal franking machines. It is appreciated that finished mailers 142 may need to be flipped prior to franking.

As seen further in FIG. 4, finished mailers 142 are preferably turned up on edge and moved into a vertical stacking mechanism. Alternatively, envelopes are turned on edge prior to scoring and gluing of top flaps 222, which are scored and glued while the envelopes are in a vertical position. The finished mailers 142 are then preferably stacked on edge and grouped into bundles 150 as seen in FIG. 3B.
