Patent number: 11926306Abstract: An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.Type: GrantFiled: December 7, 2019Date of Patent: March 12, 2024Assignee: ROBERT BOSCH GMBHInventors: Dirk Foerch, Verena Barske, Andreas Krautter, Michael Bunk, Peter Ziegler, Ulrike Schaefer

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

Patent number: 7367558Abstract: A machine for processing printing material sheets has a signal generator for position monitoring and a sheet delivery. The sheet delivery has a first conveying device, for example with a holding crossmember, for leading sheet ends and a second conveying device, for example with a holding crossmember, for trailing sheet ends. The signal generator is disposed in the sheet delivery.Type: GrantFiled: September 24, 2004Date of Patent: May 6, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Markus Möhringer, Paul Nicola, Marius Stelter

Patent number: 7334790Abstract: Sheets are conveyed through a rotary press with linear travel grippers. The novel conveying apparatus prevents collisions between the grippers and printing unit cylinders. The grippers are fixed to circulating links to convey a sheet through a nip between two cylinders that interact during printing. The links and the cylinders are coupled to drives that can be activated separately. In each case a collision disk is mounted on a shaft journal of at least one cylinder. A slip clutch is provided between the collision disk and the cylinder. A braking element is coupled to the grippers which, in the event of non-synchronous running with the cylinder, runs onto the collision disk and prevents the collision disk from moving.Type: GrantFiled: October 21, 2005Date of Patent: February 26, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Markus Möhringer

Patent number: 7261291Abstract: A sheet-processing machine contains at least one processing station in the form of a printing unit, and a delivery with an endless conveyor and after-grippers that are guided by a mechanism connected to a drive. The after-grippers take over the processed sheets from the endless conveyor and release them over a stack. The sheet-processing machine provides for it to be possible for the mechanism to be set to positions that are correlated with different formats of the processed sheets, and for the drive that actuates the mechanism to keep the mechanism at one and the same phase angle with respect to the printing unit in each of the positions. Therefore, even in the event of different formats of the processed sheets, user-friendly placing of the stack is possible.Type: GrantFiled: October 27, 2003Date of Patent: August 28, 2007Assignee: Heidelberger Druckmaschinen AGInventors: Peter Förch, Markus Möhringer, Paul Nicola

Patent number: 7234395Abstract: A device for conveying a sheet through a printing machine includes a cylinder, formed with a channel wherein grippers are disposed for holding the sheet at a leading edge, a chain conveyor with grippers fixed to endless chains for holding and picking up the sheet at its leading edge from the cylinder and for holding the sheet at its trailing edge, and rotating sprockets carrying the chains. An actuating device is provided for opening and closing the grippers, and a drive is provided for the cylinder and the sprockets. Gripper pads and gripper tips for the trailing-edge grippers, in opened condition of the grippers, are able to run past the cylinder. The gripper pads and tips lie underneath a path described by the sheet. The trailing-edge grippers are closable in a rotational angle region wherein the chains run off the sprockets for the cylinder.Type: GrantFiled: December 10, 2004Date of Patent: June 26, 2007Assignee: Heidelberger Druckmaschien AGInventors: Peter Förch, Markus Möhringer, Paul Nicola, Marius Stelter
