Definitions

  • This invention pertains generally to a system and method for converting a stream of document pages printed in "lazy-portrait" formatting (printing across the continuous paper web to produce paired portrait orientated pages) into acceptably oriented pages that are then processed and grouped into pre- designated document sets with continuously numbered pages.
  • FIG. 2 depicts a pair of traditionally formatted pages that are then separated/cut- apart and simply stacked on top of one another, as shown in FIG. 3, to produce a correctly page-sequences document set.
  • printers that function in this manner are the IBM InfoPrint 4000 and Oce VahoStream 7000.
  • a typical traditional printing system is seen in FIG. 4. where a continuous stream of traditionally printed sheets (such as the ones shown in FIG. 1 and/or FIG. 2) comes in from the far left and moves into a slitter that separates the single steam into two streams of continuous sheets that then enter a cutter and collator for further processing to generate correctly page-sequenced document sets (as illustrated in FIG. 3 for two cut sheets).
  • paper is printed in a lazy-portrait narrow-end to narrow-end (LPEE) format, which is a means for more efficient and cost effective printing of variable and form data onto paper oriented in a lazy-portrait orientation.
  • LPEE lazy-portrait narrow-end to narrow-end
  • lazy-portrait (also known in the industry as “rotated landscape” when a printer merely uses a traditional printer head alignment spanning the entire page to print a rotated image) is defined as a portrait oriented page that is generated by printing the page from one wide edge to the other wide edge (side to side) and not from narrow edge or end to narrow edge or end (top to bottom or visa-versa), as is done in every other currently existing printing system.
  • the critical issue with the subject invention is that when a pair of head- to-head or bottom-to-bottom pages are printed on a continuous stream of paper, the single stream of paper with the paired images must then be separated/slitted into two separate streams of paper with one stream being flipped over to correctly orient the final pages when cut and stacked into a document set.
  • the current subject invention presents a system and method for accomplishing this sheet flipping process by flipping one entire stream of post-slitted sheets.
  • Patent No.: 6,994,005 (an apparatus for slitting, merging, and cutting a continuous paper web) describes an in-line turn-bar that is positioned after slitting and prior to merging the two streams, but this invention only positionally moves one slit lane of paper to overlap with another slit lane of paper, without turning over the obverse to reverse orientation (or face to back orientation).
  • This patent differs from the subject invention in that, since there is no need, suggestion, or teaching to so, it does not turn over the paper orientation.
  • Patent No.: 6,595,465 (a turn-bar assembly for redirecting a continuous paper web) describes turning a single web of paper to reorient the travel direction and, in addition, to optionally flip the paper web from obverse to reverse (face up to face down) image orientation in this reoriented travel direction.
  • This patent differs from the subject invention in that it reorients the paper direction, which is not associated with the manner in which a turn-bar is employed in the subject invention.
  • An object of the present invention is to provide a paper handling system that orients lazy-portrait narrow-end to narrow-end format printed sheets into correctly page-sequenced document sets.
  • Another object of the present invention is to furnish a paper handling system that flips one of two paired lazy-portrait narrow-end to narrow-end format printed sheets to generate printed sheets that have correctly sequenced pages that are assembled into desired document sets.
  • a further object of the present invention is to supply a paper handling system that produced correctly page-sequenced document sets from a continuous web of lazy-portrait narrow-end to narrow-end (LPEE) format printed sheets by slitting a continuous stream of LPEE paired sheets into two streams, flipping one of the two streams, cutting each stream, and collating the cut sheets into correctly page-sequenced document sets.
  • LPEE lazy-portrait narrow-end to narrow-end
  • Yet a further object of the present invention is to describe a method that flips one of two paired lazy-portrait narrow-end to narrow-end format printed sheets to generate printed sheets that have correctly sequenced pages that are assembled into desired document sets.
  • Still yet another object of the present invention is to relate a method that produced correctly page-sequenced document sets from a continuous web of lazy-portrait narrow-end to narrow-end (LPEE) format printed sheets by slitting a continuous stream of LPEE paired sheets into two streams, flipping one of the two streams, cutting each stream, and collating the cut sheets into correctly page-sequenced document sets.
  • LPEE lazy-portrait narrow-end to narrow-end
  • LPEE lazy-portrait narrow-end to narrow-end
  • the term "lazy-portrait” is defined as a portrait oriented page that is generated by printing the page from one wide edge to the other wide edge (side to side) as it passes through a printer and not from narrow edge or end to narrow edge or end (top to bottom or visa-versa), as is done in every other currently existing printing system.
  • FIG. 1 is a depiction representing the PRIOR ART, wherein four total sheets are shown with paired/duplexed-document pages printed side-by-side, with all side-by-side pages oriented in traditional portrait-parallel fashion to one another.
  • FIG. 2 is a depiction representing the PRIOR ART, wherein two total sheets (still physically connected together) are shown with paired/duplexed- document pages printed side-by-side, with all side-by-side pages oriented in traditional portrait-parallel fashion to one another.
  • FIG. 3 is a depiction representing the PRIOR ART, wherein two total sheets are shown (printed as traditional side-by-side paired/duplexed- document pages, with all side-by-side pages oriented in the traditional portrait- parallel fashion to one another) separated and directly stacked on top of one another to generate a correctly page-sequenced document.
  • FIG. 4 is a picture of a PRIOR ART printing, slitting, cutting, and collating system that merely processes traditional side-by-side portrait-parallel printed pages into documents sets.
  • FIG. 5 illustrates the subject invention's formatting technique that produces lazy-portrait documents wherein four total printed sheets are depicted in a duplexed lazy-portrait head-to-head page orientation and printed on a continuous web in two printing lanes (simplexed printing jobs are only printed on one side of a sheet, thereby making assembly of a multi-page document more simplistic than with the duplexed embodiment which requires a sheet flipping process step for one of paired sheets relative to the other sheet that is the main focus of the subject invention).
  • FIG. 6 shows the subject invention's formatting technique that produces lazy-portrait documents wherein a pair of printed sheets is depicted in a duplexed lazy-portrait head-to-head page orientation and printed on a continuous web in two printing lanes.
  • FIG. 7 shows the subject invention's ability to flip one of the paired sheets seen in FIG. 6 to produce correctly page-sequenced sheets (during normal operation, an entire stream of sheets are flipped and matched with its appropriate mate from the original pairing).
  • FIG. 8 shows a turn-bar assembly used to flip only one stream of the two streams of paper generated by a slitter and positioned between the slitter and a cutter.
  • FIG. 9 is a picture showing the physical location of the turn-bar assembly (superimposed on one stream of sheets for flipping that stream of the two slitter-generated streams) between an exemplary slitter and exemplary cutter.
  • FIG. 1 through FIG. 9 the present invention is embodied in the apparatus generally shown in FIG. 1 through FIG. 9. It will be appreciated that the system, method, and apparatus may vary as to configuration and as to details of the parts, and that the method may vary as to the specific steps and sequence, without departing from the basic concepts as disclosed herein.
  • FIG. 2 depicts a pair of traditionally formatted pages that are then separated/cut-apart and simply stacked on top of one another, as shown in FIG. 3, to produce a correctly page-sequences document set.
  • FIG. 4 depicts a continuous stream of traditionally printed sheets (such as the ones shown in FIG. 1 and/or FIG. 2) coming in from the far left and moving into a slitter that separated the single steam into two streams of continuous sheets that then enter a cutter and collator for further processing to generate correctly page-sequenced document sets (a illustrated in FIG. 3).

  • the current subject invention presents a system and method for accomplishing this sheet flipping process by flipping one entire stream of post-slitter sheets.
  • the subject system/method provides a novel method for handling the lazy-portrait narrow-end to narrow-end printed sheets that are, initially, connected to each other as shown in FIG. 6.
  • FIG. 6 on the left side of the web, the side of the sheet presented to the viewer is the BACK of sheet 1 , whereas on the right side of the web, the side of the sheet presented is the FACE of sheet 2.
  • these two sheets must come together like butterfly wings, i.e. one side has to be flipped over onto the other, as clearly shown in FIG. 7.
  • the second requirement is easily met for all ordinary sizes of forms, certainly all those for which the length is 12 inches or less.
  • the first requirement can be met by employing a device known as a turn-bar.
  • a suitable turn-bar assembly 90 is a series of rollers 100, 105, and 1 10.
  • the LPEE formatted web WB enters from the left, is slit by a slitter in region SWB into two streams of sheets 80 (marked with circles on the showing faces) and 85 (marked with triangles of the showing faces), and then one stream 85 is flipped or inverted 1 15 (marked with squares on the reverse faces from the triangle-marked faces) on the fly during processing by the turn-bar assembly 90.
  • Turn-bars are often utilized in printing processes, but for different reasons than apply for the subject invention.
  • the turn-bar assembly 90 resides between the slitter and cutter/collator to accept one stream of sheets 85.
  • the turn-bar assembly 90 (comprising individual turn-bars 100, 105, 1 10, seen in FIG. 8) effects the following series of state changes to one stream of sheets 85: 1 ) turn-bar 100 performs a 90° turn with a flip; 2) turn-bar 105 performs a
  • turn-bar 1 10 performs a 90° turn with a flip.
  • the resulting "0° turn with a flip" (the stream of continuous sheets 1 15 shown in FIG. 8) processing ability is exactly the one stream state change needed for the subject invention.
  • the subject invention LPEE printing embodiment work is processed faster than traditional two-up work, because the sheets only have to travel the short distance W between cuts, rather than the longer distance L.
  • Suitable control and verification means are associated with the subject system.
  • Those means implement the subject method by generating printed pages from input data, tracking printed pages through the slitter, turn-bar assembly, cutter, and collator, and verifying the process is functioning properly and that correctly page-sequenced document sets are created.
  • Appropriately designed computer programs control the LPEE printing process, necessary paper transport processes, the slitting device, the cutting equipment, the collation of correctly page-sequenced document sets, and any additional post collation processes.
