Patent number: 9815296Abstract: A method for controlling the temperature of a sheet in a printing machine includes measuring initial temperatures in zones on the sheet. Segments of an emitter are actuated in different ways as a function of the measured initial temperatures for irradiating cooler zones to a greater extent and warmer zones to a lesser extent or not at all. A common final temperature or at least a homogenization of the temperature is therefore achieved in the zones.Type: GrantFiled: September 29, 2016Date of Patent: November 14, 2017Assignee: Heidelberger Druckmaschinen AGInventors: Andreas Mueller, Alexander Knabe, Rolf Mueller, Kai Oskar Mueller, Peter Hachmann, Michael Gieser, Wolfgang Dolz, Thomas Schmidt

Patent number: 9738472Abstract: A sheet-transporting drum includes sheet-supporting areas each being formed of a first comb segment and a second comb segment having segment teeth. At least one of the comb segments is rotatable for adaptation to a sheet format. A mechanical leading-edge gripper is provided on the first comb segment and a pneumatic trailing-edge gripper is provided on the second comb segment. A mechanical trailing-edge gripper is additionally disposed on the second comb segment and is deactivatable in particular by format adjustments. This advantageously allows either the trailing edge of a sheet to be securely held down mechanically or a full-bleed print to be applied to the sheet when the trailing edge of the sheet is held down pneumatically. A sheet-fed printing machine is also provided.Type: GrantFiled: April 21, 2016Date of Patent: August 22, 2017Assignee: Heidelberger Druckmaschinen AGInventors: Juergen Rothaug, Arno Juenger, Albert Maul, Sven Goll, Thomas Schmidt, Alexander Knabe, Daniel Conzelmann, Wolfgang Dolz, Kai Oskar Mueller, Raimund Schroeder

Patent number: 8687207Abstract: A method for determining the optimum procedure for a job change on a printing-material processing machine (10) with at least one control computer. The data of a first machine job is compared to the data of a subsequent machine job using a control computer, and the comparison is used to establish an order of the operations to be carried out during the job change. Also provided is a device for determining the optimum procedure for a job change on a printing-material processing machine (10) with at least one control computer. The control computer is intended to compare the data of a first machine job to the data of a subsequent machine job, and to use the comparison to establish an order of the operations to be carried out during the job change.Type: GrantFiled: September 12, 2003Date of Patent: April 1, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Bernhard Buck, Holger Faulhammer, Michael Krueger, Juergen Maass, Sven Mader, Stefan Maier, Kai Oskar Mueller, Matthias Noell, Martin Riese, Bernhard Roskosch

Patent number: 8402650Abstract: A method for producing a built-up cam shaft and a built-up cam shaft having a shaft are provided. A functional component is produced in a separate manufacturing process and has an internal orifice to receive the shaft. The orifice in the functional component is substantially round to receive the shaft, and an insertion mechanism is provided on the raised areas and/or at the orifice in the functional component, which allow the functional component to be pushed onto the raised areas substantially without shavings being produced. The raised areas partially dig into the orifice and in so doing connect the functional component to the shaft in a non-positive and positive manner substantially by deformation of the material of the functional component in the region of the orifice in the functional component.Type: GrantFiled: May 23, 2006Date of Patent: March 26, 2013Assignee: Thyssenkrupp Presta TecCenter AGInventor: Oskar Mueller

Patent number: 6725780Abstract: A method of driving a machine related to printing technology, wherein movable elements forming a kinematic chain are coupled with one another via at least one gear mechanism, includes infeeding torque components by a respective motor of at least one group of two motors, respectively located at least at two elements associated with one another. The torque components are of equal amplitude but have opposite directions of rotation, for suppressing disruptive oscillations at least at the one group of two motors. The amplitude of the torque components is proportional to relative rotation of the two elements associated with one another. Rotary encoders are provided to obtain signals for reproducing rotational positions of the elements.Type: GrantFiled: December 12, 2002Date of Patent: April 27, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Bernhard Buck, Holger Faulhammer, Michael Krüger, Jürgen Maass, Sven Mader, Stefan Maier, Kai Oskar Müller, Matthias Nöll, Martin Riese, Bernhard Roskosch

Patent number: 6276180Abstract: The subject matter of the invention is a method of manufacturing a shift gearwheel (1) with coaxially disposed and axially projecting shift teeth (5), which have an axial undercut. To said end, a shift gearwheel blank (1) having preformed shift teeth (5) and a forming tool (16) having corresponding tooth recesses (18) are brought into engagement and set in gyratory motion relative to one another. Further described are a device for effecting the method and a shift gearwheel (1), which may be manufactured by the method. The latter is notable for the fact that the flanks (23, 24) of the shift teeth (5) upon completion of the manufacturing method are concave so as to produce an undercut.Type: GrantFiled: February 11, 2000Date of Patent: August 21, 2001Assignees: Hirschvogel Umformtechnik GmbH, Schmid Heinrich Maschinen-und Werkzeugbau AGInventors: Manfred Hirschvogel, Peter Kettner, Hubert Nägele, Oskar Müller, Albin Giger, Hand-Ruedi Honegger
