Patent number: 10320273Abstract: A brush-commutated direct-current motor comprises a stator with a plurality of exciter poles, a rotor with a plurality of pole teeth, which is rotatable relative to the stator about an axis of rotation, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth and a commutator which is arranged on the rotor and a plurality of lamellae to which the coil windings are connected. For manufacturing such direct-current motor the coil windings are arranged on the pole teeth in winding cycles, in each of which a coil winding is wound onto each pole tooth. It is provided that on each pole tooth a first coil winding wound around the pole tooth in a first winding direction and a second coil winding wound around the pole tooth in a second winding direction opposite to the first winding direction are arranged.Type: GrantFiled: August 12, 2015Date of Patent: June 11, 2019Assignee: Brose Fahrzeugteile GmbH & Co, Kommanditgesellschaft, WuerzburgInventors: Akram Ben Helal, Walter Roeder, Norbert Heim, Johannes Bartoschek

Patent number: 8347785Abstract: A web offset press includes several printing units through which a web passes essentially in a horizontal direction. The printed web then passes to at least one first folding unit. Each of the printing units has at least one plate cylinder and one transfer cylinder which interacts with the web being printed. An effective plate width of the plate cylinder corresponds to the print image of at least eight upright or prone printed pages in a BIN 4A format. The printed web is slit longitudinally into a plurality of web strands: A first number of these web strands are supplied to the first folding apparatus. At the same time, a second number of web strands, produced by the slitting of the same web, are supplied to a second folding apparatus for further processing.Type: GrantFiled: May 27, 2009Date of Patent: January 8, 2013Assignee: Koenig & Bauer AktiengesellschaftInventors: Andreas Ewald Heinrich Bernard, Klaus Ludwig Christmann, Burkard Otto Herbert, Bernd Ulrich Herbert Keller, Erwin Paul Josef Lehrieder, Klaus Walter Röder, Karl Robert Schäfer

Patent number: 7832682Abstract: A material roll is transported to a roll changer by being arranged on a transport carriage. The material roll and transport carriage are placed on a transfer table which is moved into position between journal bearings of the roll changer. The transfer table is adapted to move the material roll transversely and along a longitudinal axis of the material roll and can pivot in a horizontal plane. An inclined position of the material roll, arranged on the transfer table, is determined by sensors. In this determined, axially aligned position, the material roll is axially aligned on the bearing journals. The roll size of the material is determined. An axially aligned position for roller support arms of a roll carrier of the roll changer is determined as a function of the determined roll size. An axially aligned position of the transfer table is determined as a function of the determined roll size and the determined inclined position of the material roll.Type: GrantFiled: May 17, 2006Date of Patent: November 16, 2010Assignee: Koenig & Bauer AktiengesellschaftInventors: Martin Richard Keller, Erwin Paul Josef Lehrieder, Walter Ritter, Klaus Walter Röder

Patent number: 7094015Abstract: A device is used to convey empty rolls that have been removed by at least one roll changer of a web-fed rotary printing press. At least one empty roll receptacle can be displaced between the roll changer, where the empty rolls are held by the receptacle after they are removed by the roll changer, and an emptying station where the empty rolls are removed from the receptacle. A collection receptacle is provided at the emptying station. The empty rolls are emptied from the empty roll receptacle to the collection receptacle.Type: GrantFiled: November 27, 2002Date of Patent: August 22, 2006Assignee: Koenig & Bauer AktiengesellschaftInventors: Lothar Franz Hohmann, Klaus Walter Röder

Patent number: 6334587Abstract: An active code carrier is located inside a spare paper roll that includes a tube or core. The code carrier interacts with either a reading head, or a writing head. This enables roll-specific data to be read or updated at any time. This is particularly useful for automated roll transport and roll handling systems.Type: GrantFiled: August 30, 1999Date of Patent: January 1, 2002Assignee: Koenig & Bauer AktiengesellschaftInventor: Klaus Walter Röder

Patent number: 6311823Abstract: A conveying device for a paper web roll in a web-fed printing press includes a conveyor car that rides on a support track recessed into the floor. A pair of alignment rails are situated adjacent to the support track. These alignment rails, or at least one of them is moveable between a rest position flush with the floor, and a roll alignment position in which it is inclined, at an acute angle with respect to the floor. In the roll alignment position, both of the alignment rails are inclined with respect to the floor.Type: GrantFiled: February 22, 2000Date of Patent: November 6, 2001Assignee: Koenig & Bauer AktiengesellschaftInventors: Günter Johann Bierbaum, Klaus Walter Röder

Patent number: 4568323Abstract: Strip steel stamping knives (1) and, if desired, the strip steel folding rules (2) of a strip steel stamping tool are provided in slots (3, 4) in a carrier plate (5). The strip steel stamping knives and, if desired, the strip steel folding rules protrude downwardly from the carrier plate to cooperate with a counter stamping plate (7). The backs of the stamping knives (1) and, if desired, of the folding rules (2), face a hardened pressure plate (9). In order to achieve an automatic height or elevational adjustment of the stamping knives (1), and if desired, of the folding rules (2), the backs of the stamping knives and, if desired, of the folding rules, are also constructed as hardened cutting edges (11, 12). An intermediate plate (10) is placed between the carrier plate (5) and the pressure plate (9).Type: GrantFiled: May 7, 1984Date of Patent: February 4, 1986Assignees: R & S Stanzformen GmbH, Karl Stursberg KGInventor: Walter Roeder
