20110187038 | DEVICE FOR DEPOSITING FOR A PRINTING MACHINE - The invention relates to a device for depositing sheets for a printing machine, preferably for an electrophotographically operating printing machine, said device comprising at least one sheet transport member which can be driven so as to rotate and which is provided for the detection of a lead edge of a sheet and for depositing the sheet after it has covered a rotating path. Therefore, the object of the invention is to make depositing a sheet and turning over a sheet, in particular also larger and/or thinner sheets, more reliable with the use of a device of the aforementioned type. In accordance with the invention, this object is achieved by a device which is characterized by a blower arrangement for the application of air to the sheet to be deposited. Due to the application of air, the sheet to be deposited and to be turned over is advantageously supported by an additional momentum and by its inherent stiffness, so that the sheet will unroll fully after its lead edge has been caught by the rotation. | 08-04-2011 |

20080230983 | Device and Tray For Depositing Sheets - The invention relates to a device for depositing sheets in a machine that preferably processes sheets by graphic means, in particular for a printing machine, preferably for an electrophotographically operating machine, comprising at least one deposit tray for depositing and preferably also for stacking processed sheets. Furthermore, the invention relates to a deposit tray for a device of the aforementioned type. The object of the invention is to provide a device or a deposit tray of the aforementioned type, which permits a controlled depositing and stacking of sheets, in particular, at greater sheet-processing speeds, and, preferably, in a cost-effective manner. In accordance with the invention, this object is achieved in that a deposit surface of the deposit tray is arranged, or can be arranged, at an angle that deviates from the horizontal. | 09-25-2008 |

20100059931 | DEVICE FOR DEPOSITING SHEETS IN A STACK - The present invention relates to a device for depositing sheets for a printing machine, said device comprising at least one rotating drivable sheet transport element, which is designed to receive or grasp a leading edge of a sheet and deposit said sheet on a stack after said sheet has traveled a path of rotation, and comprising at least one drag element for pulling a sheet that has been deposited on the stack toward a mechanical stop. With the present invention, the drag element is coupled with the rotation of the sheet transport element and is arranged in such a manner that said drag element can assume an inoperative position within the region covered by the rotating sheet transport element, and that said drag element, in order to perform its dragging function, can be moved at least partially out of the region covered by the rotating sheet transport element. | 03-11-2010 |
