Turn-bar document handling apparatus for utilization with a lazy-portrait document printing system

A system for printing and assembling correctly page-sequenced document sets that are formatted and printed in a lazy-portrait narrow-end to narrow-end (LPEE) formatting on a continuous web of printable material, wherein the continuous web has a central axis in a direction of motion of the continuous web during printing and wherein each said document set is comprised of one or more material sheets with each material sheet having a first side page and a second side page with each material sheet having a top narrow-edge, a distal bottom narrow-edge, and two side long-edges and printed merged document information for each printed page having a head region and a bottom region, wherein said printed merged document information head region is printed proximate one of said material sheet narrow-edges to produce paired first and second material sheets and said paired material pages have a common axis that is perpendicular to the central axis of the continuous web, wherein when said document set is comprised of more than one printed page, even number printed pages are printed on one of said first and said second sides of said material sheet and odd number printed pages are printed on an opposite side of said first and second sides of said material sheet, comprising:

• a) a printer, wherein said printer includes a printer head that prints a portion of both of said paired first and second material sheets;
• b) a slitter for separating the LPEE formatted document pages into a first stream of continuous sheets containing said first material sheets and a second stream of continuous sheets containing said second material sheets;
• c) a turn-bar assembly positioned to flip said first stream of continuous sheets thereby aligning a printed page sequence for more than one page documents sets of said first stream with a page orientation of said second stream that leads to the assemble of correctly page-sequenced documents sets;
• d) a cutter that produces separates material sheets from both said flipped first and said second streams of continuous sheets;
• and
• e) a computer controller having programming for directing printing and tracking of said LPEE formatted documents pages and verifying the formation of correctly page-sequenced documents sets.

• d) a collator for collating said separate material sheets into the correctly page-sequenced document sets;
• and
• e) control means having programming for printing and tracking said LPEE formatted document pages and overseeing the assembly of the correctly page-sequenced document sets;
• and
• f) color printing means for simultaneous printing in color on a limited region of both said first material sheet and said second material sheet proximate where said first material sheet and said second material sheet are paired at their said narrow-end.

A method for printing and assembling correctly page-sequenced document sets produced on a continuous web of material by a printer formatting the document sets in a lazy-portrait narrow-end to narrow-end (LPEE) format formatting, wherein the continuous web has a central axis in a direction of motion of the continuous web during printing and wherein each said document set is comprised of one or more material sheets with each material sheet having a first side page and a second side page with each material sheet having a top narrow-edge, a distal bottom narrow-edge, and two side long-edges and printed merged document information for each printed page having a head region and a bottom region, wherein said printed merged document information head region is printed proximate one of said material sheet narrow-edges to produce paired first and second material sheets and said paired material sheets have a common axis that is perpendicular to the central axis of the continuous web, wherein when said document set is comprised of more than one printed page, even number printed pages are printed on one of said first and said second sides of said material sheet and odd number printed pages are printed on an opposite side of said first and said second sides of said material sheet, comprising the steps:

• a) printing by means of a printer a portion of both of said paired first and second material sheets simultaneously;
• b) slitting by means of a controller-operated slitter apparatus the LPEE formatted documents pages into a first stream of continuous sheets containing said first material sheets and a second stream of continuous sheets containing said second material sheets;
• c) flipping by means of a flipping apparatus said first stream of continuous sheets thereby aligning a printed page sequence for more than one page document sets of said first stream with a page orientation of said second stream that leads to the assemble of correctly page-sequenced documents sets;
• d) cutting by means of controller-operated cutting apparatus both said first and said second stream of continuous sheets into separate material sheets;
• and
• e) directing said printing and tracking of said LPEE formatted documents pages and verifying the formation of correctly page-sequenced documents sets by means of a computer and associated programming.
