| 20100178090 | DEVICE FOR TURNING OVER SHEET MATERIAL - The invention relates to a device for turning over sheet material, preferably sheets of printing material, in a printing machine, preferably for verso-printing, preferably in a digital printing machine, preferably an electrophotographic printing machine, said device comprising driven web-shaped segments extending essentially parallel to each other over at least one section, said web-shaped segments clamping the indi-vidual sheet between them and thus transporting said sheet along a transport path, thus turning over said sheet. The object of the invention is to provide a turn-over device of the aforementioned type, which grasps the sheets with the belt segments and guides them in a manner so as to be turned over, in an easier and more secure manner. This object is achieved in that the clamping belt segments move together on the sheet transport path around at least one deflecting element which deflects them by approximately 180° in such a manner that the previously upper side of the sheet becomes the lower side of the sheet | 07-15-2010 |
| 20100209160 | SYSTEM AND METHOD FOR CROSS-PROCESS CONTROL OF CONTINUOUS WEB PRINTING SYSTEM - A system and method for controlling the cross-process position of ink print heads including identifying a first roll error frequency related to a circumference of a first roll, identifying a first roll error phase with respect to a reference location along a process path, identifying a first roll error amplitude of cross-process motion, identifying a second roll error frequency related to a circumference of a second roll, identifying a second roll error phase with respect to the reference location, identifying a second roll error amplitude of cross-process motion, and controlling the cross-process position of a first and second print head based upon the identified first roll error frequency, first roll error phase, first roll error amplitude, second roll error frequency, second roll error phase, and second roll error amplitude, wherein the first print head is axially spaced apart from the second print head along the process direction. | 08-19-2010 |
| 20110064498 | IMAGE FORMING SYSTEM AND IMAGE FORMING DEVICE - A first image forming component forms an image on one side of the continuous paper conveyed by a first conveyance component based on a first reference position. The first reference position is a position that is disposed away from the first side edge of the continuous paper by a first width which is one of a measured width of the continuous paper and a pre-specified width for the continuous paper. A second image forming component forms an image on the other side of the continuous paper conveyed by a second conveyance component based on a second reference position. The second reference position is a position that is disposed away from the second side edge by a second width which is the other of the measured width of the continuous paper and the pre-specified width for the continuous paper. | 03-17-2011 |
| 20120308286 | SIMPLIFIED BELT SEAM SKIP IN CONTINUOUS WEB FEED MACHINES - A system that avoids any stopping or reversing of the web direction in a continuous feed printer, instead maintaining consistent process speed, only requiring a slowing and speeding up of the web to cycle through the PR belt seam. This is done by forming a web loop and then immediately flattening the loop after passage of the seam through the transfer zone that includes two transfer BTR rolls with alternating transfer operations, but simultaneous transfer for short periods. Two vacuum assist rolls, one located between the two bias transfer rolls controls the formation of the web loop. A pair of nip forming rolls upstream of the first transfer station and a second vacuum assist roll downstream of the second transfer station control the size of the loop. | 12-06-2012 |
| 20150293484 | IMAGE FORMATION APPARATUS AND IMAGE FORMATION METHOD - An image formation apparatus includes: an image formation unit that forms an image on continuous paper; a paper conveyance unit that conveys the paper through a conveyance path; a deviation correction unit that corrects deviation of the continuous paper by moving the paper on the conveyance path in a paper feed intersecting direction; a paper position measurement unit that measures a paper position in the paper feed intersecting direction of the paper on the conveyance path; and a control unit that controls the image formation unit and the deviation correction unit, wherein during stop of a conveyance operation, the control unit moves the paper to a predetermined position in the paper feed intersecting direction by deviation correction by the deviation correction unit, and during the conveyance operation, the control unit decides an image formation position in a main scanning direction in the image formation. | 10-15-2015 |
| 20150346644 | IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM - An image forming apparatus includes a conveying unit that conveys a recording medium S from an introduction conveying section to a transfer section. The conveying unit includes: a conveyance supporting base that is supported so as to be able to be inserted into and detached from the apparatus body via a movement mechanism, and a plurality of conveying members that is attached to the conveyance supporting base in a detachable manner, and that forms a conveying path through which the recording medium is conveyed. | 12-03-2015 |
| 20160041515 | ROLL SHEET IMAGE FORMING APPARATUS - A roll sheet image forming apparatus includes an introduction opening and a guide plate. Instead of a continuous sheet held in an apparatus main body, a continuous sheet for option feeding provided at an outside is introduced into the apparatus main body through the introduction opening. The guide plate is for splicing a lead sheet and a continuous sheet. When feeding the continuous sheet, a feeding unit is pulled out from the apparatus main body, a lead sheet is set to be conveyable towards an image forming unit, the feeding unit is again accommodated in the apparatus main body, a front end of the continuous sheet is placed on the guide plate, a rear end of the lead sheet is placed on the guide plate through the introduction opening, the rear end and the front end are spliced by a bonding member and then the feeding unit operates. | 02-11-2016 |
| 20160048100 | DEVICE TO INSERT WEB-SHAPED RECORDING MEDIA INTO THE TRANSPORT PATH OF PRINTERS - In a device or method for insertion of a recording medium into a transport path of a printer an elastic insertion plate is provided that, at an end facing away from a transport direction of the transport path, has a clamper to accept the recording medium to be inserted as well as at least one transport surface for interaction with at least one transport roller. The clamper comprises a magnet and an associated metal surface that accepts a leading end of the recording medium between the magnet and the metal surface such that the recording medium leading end is releasably clamped. | 02-18-2016 |
