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 |
20150225193 | DEVICE AND METHOD FOR SUCTIONING A SHEET FROM A SHEET STACK AND SHEET-FED ROTARY PRINTING MACHINE AND PUNCH HAVING THE DEVICE - A device and a method for raising and positioning an object, for example a sheet from a sheet stack, uses a whirlwind to generate a negative pressure for generating a retaining force and uses interference air for releasing the retaining force. | 08-13-2015 |
20150239235 | LIFTING SUCKER WITH PNEUMATICALLY CONTROLLABLE SUCTION CUP AND PUNCH AND SHEET-FED ROTARY PRINTING PRESS HAVING THE LIFTING SUCKER - A lifting sucker for separating sheets from a sheet stack includes a suction cup formed as a double-walled bellows sucker having at least one suction chamber that can be acted on pneumatically to contract the bellows sucker. A punch and a sheet-fed rotary printing press having the lifting sucker are also provided. | 08-27-2015 |
20150241875 | METHOD AND APPARATUS FOR HOLDING DOWN A SHEET ON A FEED TABLE OF A SHEET-PROCESSING MACHINE - A method and an apparatus for holding down a sheet on a feed table of a sheet-processing machine include a lowerable smoothing bar which can be driven according to a speed profile in time with the sheet-processing machine, which results in a targeted deflection of the smoothing bar. The deflection is preserved for the purpose of smoothing the sheet from the middle to the side. | 08-27-2015 |
20160075527 | METHOD AND DEVICE FOR COMBINING AN AUXILIARY STACK AND A MAIN STACK, SHEET-FED PRINTING PRESS OR SHEET PUNCHING MACHINE AND METHOD FOR DRIVING AN AUXILIARY STACK CARRIER - A method and a device for combining an auxiliary stack and a main stack include a rake carrying the auxiliary stack and being abruptly movable out of a stack area to prevent sheets that contact the rake from being entrained and to preserve the structure of the stack. A sheet-fed printing press or sheet punching machine having the device is also provided. | 03-17-2016 |
20160075528 | DEVICE FOR COMBINING AN AUXILIARY STACK WITH A MAIN STACK AND SHEET-FED PRINTING PRESS OR SHEET PUNCHING MACHINE HAVING THE DEVICE - A device for combining an auxiliary stack with a main stack includes an auxiliary stack carrier which holds the auxiliary stack and which can be moved out of the stack area for combining the stacks. A holding device firmly holds a lower sheet of the auxiliary stack and an upper sheet of the main stack as the auxiliary stack carrier is moved out of the stack area, in order to maintain a good stack structure. A sheet-fed printing press or sheet punching machine having the device is also provided. | 03-17-2016 |
20160082755 | DEVICE FOR FEEDING SHEETS AND DIGITAL SHEET-FED PRINTING MACHINE HAVING THE DEVICE - A device for feeding sheets to a digital sheet-processing machine includes a feed drum for transporting the sheets to the printing machine. At least two transport paths are provided to convey the sheets to be processed to the feed cylinder in at least two different positions from where the sheets are taken over by a gripper device of the feed cylinder and accelerated to processing speed. A digital sheet-fed printing machine having the device is also provided. | 03-24-2016 |
