| 20080271623 | Method and Device for Producing Printed Products - The invention relates to printed products which are folded once, twice or three times, are ejected by a rotary printing machine, or produced by a rotation, are stored temporarily, and then ejected by storage units. The printed products are folded essentially in the center and stitched optionally along the additional fold (F). They are then cut in such a way that the first folded edges (F. | 11-06-2008 |
| 20090293745 | SHEET MONITOR FOR PERFECTOR - A perfecter includes: a transfer cylinder ( | 12-03-2009 |
| 20120118185 | SHEET-FED PERFECTING PRINTING PRESS WITHOUT SHEET REVERSAL - A sheet-fed, rotary, printing press for printing on both sides of sheets without a sheet reversing device, includes printing units having a modular construction. Each module includes at least a plate cylinder, a blanket cylinder, an impression cylinder, a transfer cylinder and at least one drive wheel. Modules for printing on the first side of the sheets and modules for printing on the second side of the sheets have an identical construction and are disposed in such a way that one is rotated through 180° relative to the other about an axis extending in a sheet processing direction. | 05-17-2012 |
| 20120247354 | PERFECTING PRINTING UNIT AND TOWER - A continuous-blanket-contact perfecting printing tower that includes at least one perfecting printing unit that includes one-around circumference plate cylinders and a first blanket cylinder that is either one-around in circumference or two-around in circumference and also includes a second blanket cylinder that is either two-around in circumference or three-around in circumference. When the perfecting printing units are stacked in a continuous-blanket-contact tower configuration, the two-around circumference blanket cylinders and/or three-around circumference blanket cylinders allow more distance between the plate cylinders of adjacent perfecting printing units compared to continuous-blanket-contact designs that use only one-around circumference blanket cylinders. The additional distance between the plate cylinders of adjacent perfecting printing units created by the inclusion of two-around circumference blanket cylinders and/or three-around circumference blanket cylinders provides more space for more and/or larger rollers, oscillators, dampeners and/or print enhancement devices and the like, to be situated around the plate cylinders. | 10-04-2012 |
| 20120272847 | PRINTING METHOD AND PERFECTING PRINTING PRESS FOR RECTO AND VERSO PRINTING ON SHEETS - A printing method for printing on both sides of sheets in a perfecting printing press includes first, second and third steps. In the first step, the sheet is transported on a first cylinder, with the first cylinder having its temperature controlled to a first temperature, and the sheet is printed on a first side. In a second step, the sheet is turned by a turning device. In a third step, the sheet is transported on a second cylinder, with the second cylinder having its temperature controlled to a second temperature, which is different from the first temperature, and the sheet is printed on a second side. A perfecting printing press for recto and verso printing on sheets for implementing the printing method is also provided. | 11-01-2012 |

| 20080271624 | Sheet-Fed Printing Press and Printing Method - A sheet-fed printing press exhibiting excellent workability is provided, in which even by powder spray in print work equal to conventional one, any printing plate can be used because wear is enhanced by the printing press body and with which low cost can be realized by eliminating the need for changing the printing plate in the middle. A single-side printing sheet-fed printing press, including a print unit, and a sheet fed section having a feeder portion for feeding a sheet to the print unit, is characterized in that at least one of the feeder portion and the print unit has a dust removing means. | 11-06-2008 |
| 20080289522 | Apparatus for Turning a Sheet During Transport Through a Printing Press - An apparatus for turning a sheet during transport through a printing press provides better printed results as a result of improved sheet guidance. A transfer drum has gripper systems disposed in channels for holding the sheet at the leading and trailing sheet edge, and guide elements covering the channels. | 11-27-2008 |
| 101231000 | Feeding or delivering | 1 |
| 20080229947 | Deliver Drum and Perfecting Printing Press Having the Delivery Drum - A delivery drum includes at least one supporting shell for supporting a printed sheet and for producing a vacuum region between the supporting shell and the printed sheet. The supporting shell extends over the entire width of the printed sheet. A circumferential length, which is at least one quarter of the sheet length of the printed sheet, is disposed between the sheet start of the printed sheet and the start of the vacuum region. | 09-25-2008 |
