Patent number: 7891650Abstract: An apparatus for the removal of proof sheets from a sheet-processing machine has at least one sheet catcher provided with a gripper device. The gripper draws the sheet out of the stacking region. A lower sheet catcher is first moved into the stacking region above the sheet stack. Following a deposition of at least one proof sheet, the sheet is gripped with the gripper device, and following sheets are held back with an upper sheet catcher. Then the proof sheet is drawn out of the stacking region by moving the lower sheet catcher and the gripper device back.Type: GrantFiled: March 7, 2008Date of Patent: February 22, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Markus Möhringer, Paul Nicola, Marius Stelter, Ralf Wadlinger

Patent number: 7448625Abstract: Sheets are conveyed through a printing machine with improved reliability of the suction grippers. The apparatus for conveying a sheet through a printing machine has a cylinder with grippers in a channel for holding the sheet at its leading edge, circulating grippers for holding and for transferring the sheet from the cylinder at its leading edge, and circulating, radially positionable suction grippers for holding the sheet at its trailing edge. An actuating apparatus opens and closes the grippers and controls vacuum for the suction grippers. A drive for the cylinder and circulating grippers and suction grippers. A control device switches on and off the sheet feed to the cylinder. The suction grippers can be moved in the radial direction into a rest position when the sheet feed is switched off.Type: GrantFiled: August 30, 2005Date of Patent: November 11, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Daniel Gronych, Markus Möhringer, Paul Nicola, Marius Stelter, Ralf Wadlinger

Patent number: 7427064Abstract: A machine for processing a sheet of printing material contains a first chain conveyor having a first gripper bar for holding a leading edge of the sheet, and a second chain conveyor having a rear gripper bar for simultaneously holding a trailing end of the sheet. A processing device is assigned to the chain conveyors for processing the sheet. A distance changing device is provided for temporarily reducing a gripper distance between the two gripper bars and, consequently, producing a sheet sag required for the processing of the sheet carried out by the processing device. The distance changing device defines a first circulation path of the front gripper bar, determined by the first chain conveyor, and a second circulation path of the rear gripper bar, determined by the second chain conveyor, running locally differently from each other. The processing device can be, for example, a sheet smoother.Type: GrantFiled: July 27, 2005Date of Patent: September 23, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Markus Möhringer, Stefan Mutschall, Paul Nicola, Marius Stelter, Ralf Wadlinger
