Abstract
Abstract A cut and deflect paper system for allowing printed documents to be exited from the system while scrap paper ahead of, intermediate, or behind said printed documents are cut and deflected into a scrap or waste area within the system. In a continuous web document-printing system, under control of a control electronics, a brake halts the paper movement through the system and a knife cuts the paper into predetermined lengths of normal document sizes. A deflector system in the paper path following the cutter allows printed documents to pass out of the system while it deflects scrap sheets into said scrap area in the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
In a data processing system including a data printer for printing information on a continuous web of record paper, cut and deflect apparatus comprising first drive means for advancing said record paper from said data printer through said cut and deflect apparatus, brake means for halting the movement of said paper by said first drive means, knife means for cutting said paper after the halting thereof, control electronics means for monitoring the operation of said data printer to selectively control said brake means and said knife means, and sheet deflector means responsive to said control electronics means for deflecting into a first path that cut paper that contains printed information thereon and into a second path that cut paper with a lack of printed information thereon.
Claim 2
Dependent Claim
126 words
In a data processing system including a data printer for printing information on a continuous web of record paper, cut and deflect apparatus comprising first drive means for advancing said record paper from said data printer through said cut and deflect apparatus, brake means for halting the movement of said paper by said first drive means, knife means for cutting said paper after the halting thereof, control electronics means for monitoring the operation of said data printer to selectively control said brake means and said knife means, and sheet deflector means responsive to said control electronics means for deflecting into a first path that cut paper that contains printed information thereon and into a second path that cut paper with a lack of printed information thereon.
Claim 3
Dependent Claim
125 words
The cut and deflect apparatus as set forth in claim 1 wherein said first drive means includes a pair of tension rolls, and wherein said paper moves around one of said rolls to the point of contact of said rolls and then around the second of said rolls, said first drive means continuing to advance said paper when said brake means is actuated, the paper thereby forming a loop around one of said tension rolls, and further including second drive means between said brake means and said knife means for advancing said paper to said knife means, said second drive means operating at a substantially greater rate of speed than said first drive means to eliminate said loop formed around one of said tension rolls.
Claim 4
Dependent Claim
101 words
The cut and deflect apparatus as set forth in claim 2 further including paper flow measuring means for detecting the amount of paper moving into said cut and deflect apparatus, said control electronics means being responsive thereto and the operation of said data printer to cause said paper to be cut into uniform length documents in a data-printing condition for passage along said first path and to cut said paper into lengths of an upper and lower limit in a scrap condition for disposition thereof in a scrap disposal area along said second path upon actuation of said sheet deflector means.
Claim 5
Dependent Claim
62 words
The cut and deflect apparatus as set forth in claim 3 further including third and fourth drive means for advancing said documents and said scrap along said first and second paths respectively, said third and fourth drive means operating at a faster rate of speed Than said first drive means to quickly advance said documents and scrap away from said cutting means.
Claim 6
Dependent Claim
58 words
The cut and deflect apparatus as set forth in claim 4 further including photosensing means positioned along said second path to said scrap area for detecting the passage of scrap thereby in order to enable said control electronics to actuate said brake means and knife means to limit said scrap to said upper and lower limits of length.
Claim 7
Dependent Claim
109 words
The cut and deflect apparatus as set forth in claim 4 wherein said control electronics means includes means for detecting system conditions such that the length of paper from said data printer to said cut and deflect apparatus will be scrapped in a start print condition, the length of paper following the last document will be scrapped in a stop print condition, and the length of paper intermediate documents due to any other system condition will also be scrapped, said documents always being deflected along said first path by said sheet deflector means and said scrap paper always being deflected along said second path by said sheet deflector means.
