20080224384 | Method and Apparatus for Processing a Sheet Before the Sheet Transport in the Grip of Grippers - A method and an apparatus for improving the sheet transport in the grip of grippers in a sheet-processing machine, for example a printing press. The sheet corners of the print-free gripper edge are removed in order to increase the sheet stability and in order to avoid these limp sheet corners being able to turn over. | 09-18-2008 |
20090230609 | APPARATUS FOR ALIGNING SHEETS ON STOPS - An apparatus for aligning sheets in a processing machine includes translationally movable stops or front lays which can be driven through the use of a coupler mechanism or individually actuable electric motors. | 09-17-2009 |
20090250869 | APPARATUS FOR ALIGNING SHEETS THROUGH THE USE OF STOPS DISPOSED ON A CYLINDER - An apparatus for continuous alignment of sheets which are fed to a processing machine, includes an alignment cylinder on which stops for the sheets are disposed. The stops are pivoted out of the periphery of the alignment cylinder and moved on a translational movement path during an alignment phase. | 10-08-2009 |
20100007076 | METHOD AND APPARATUS FOR FEEDING SHEETS TO A PROCESSING MACHINE - In a method and an apparatus for feeding sheets to a processing machine, in particular a printing press, provision is made for the sheet to be accelerated to processing speed by use of at least two acceleration stations arranged one after the other. One of the acceleration stations is arranged such that the acceleration station can be displaced in order to align the sheet. | 01-14-2010 |
20100066007 | METHOD AND APPARATUS FOR FEEDING SHEETS TO A PROCESSING MACHINE - A method and an apparatus for conveying and aligning sheets being fed to a processing machine, include conveying a sheet which has been separated from an overlapping stream back into the overlapping stream in the case of a machine “stop,” wherein a rear sheet edge is raised by a mechanical or pneumatic device. | 03-18-2010 |
20100072695 | METHOD AND DEVICE FOR EJECTING DEFECTIVE SHEETS AT A FEEDER OF A PROCESSING MACHINE AND FEEDER HAVING THE EJECTING DEVICE - A method and a device for ejecting a defective sheet at a feeder of a processing machine, in particular a sheet-fed rotary printing machine, include a transporting device, which can be regulated independently of machine operation, for transporting a sheet identified as a defective sheet with deceleration in such a way that gripper devices of a cylinder cannot grip the sheet and the sheet is transported to a depositing location by the transporting device and a guide. A feeder of a sheet-fed rotary printing machine having an ejecting device, is also provided. | 03-25-2010 |
20100236354 | CAM MECHANISM HAVING A CONTROL CAM AND A CONTROL ROLLER, ALIGNMENT CYLINDER AND SHEET PROCESSING MACHINE - A cam mechanism includes a control cam and a control roller rolling on the control cam to produce a deflection of the control roller. The control cam and the control roller each have a respective anti-twist safeguard, protection or device interacting with each other and being constructed, for example, as a toothing system. An alignment cylinder for sheets and a sheet processing machine are also provided. | 09-23-2010 |
20110094401 | APPARATUS FOR CORRECTING THE POSITION OF SHEETS - In an apparatus for correcting a position of a sheet which is transported in the grip of grippers on a feed drum of a sheet processing machine, in particular a sheetfed rotary printing press, provision is made for a gripper device of the drum to be mounted in independently rotatable arranged supports and for it to be possible for each support to be driven by a step-up gear mechanism. | 04-28-2011 |
20110185931 | APPARATUS FOR FRONT/TOP LAY VERTICAL ADJUSTMENT AND SHEET-FED ROTARY PRINTING PRESS HAVING THE APPARATUS - An apparatus for the vertical adjustment of combined front/top lays in a sheet processing machine includes a front/top lay carrier shaft carrying the front/top lays jointly in such a way that it can be pivoted with respect to a front/top lay drive shaft, or thrust joints disposed in carriers or coupling links for the front/top lays in such a way that they effect a lengthening of the carriers or coupling links in order to adjust the front/top lays. A sheet-fed rotary printing press having the apparatus, is also provided. | 08-04-2011 |
20130181395 | METHOD FOR FEEDING SHEETS TO A PRINTING TECHNOLOGY MACHINE - A method for feeding sheets to a printing technology machine improves reliability of feeding sheets and reduces an acceleration time from a base speed to a production speed. The sheets are conveyed onto a feed table in shingled formation by a first drive and are individually and successively conveyed from the feed table to a first processing station of the machine by a second drive. The sheets are conveyed onto the feed table before an acceleration of the second drive to production speed is completed and the first drive is accelerated to the production speed when the processing station has reached the production speed. | 07-18-2013 |
20140026772 | SHEET GUIDING DEVICE AND SHEET BRAKE, DIECUTTER AND PRINTING PRESS HAVING THE DEVICE - A device for guiding sheets in a sheet-fed rotary printing press or diecutter includes a sheet-guiding plate with openings and a cover plate disposed parallel thereto and being displaceable by an applied operating pressure. A flexible intermediate layer disposed between the sheet-guiding plate and the cover plate has passages with a cross section which is variable by the operating pressure. A sheet brake, a diecutter and a printing press having the sheet guiding device are also provided. | 01-30-2014 |
20140174217 | APPARATUS FOR FRONT/TOP LAY VERTICAL ADJUSTMENT AND SHEET-FED ROTARY PRINTING PRESS HAVING THE APPARATUS - An apparatus for the vertical adjustment of combined front/top lays in a sheet processing machine includes a front/top lay carrier shaft carrying the front/top lays jointly in such a way that it can be pivoted with respect to a front/top lay drive shaft, or thrust joints disposed in carriers or coupling links for the front/top lays in such a way that they effect a lengthening of the carriers or coupling links in order to adjust the front/top lays. A sheet-fed rotary printing press having the apparatus, is also provided. | 06-26-2014 |
