Patent number: 9346259Abstract: A method for closed-loop or open-loop control of ink feed in lithographic offset printing presses having at least one inking unit, a control unit and an operating element for adjusting the ink feed across a predetermined ink feed control range, includes subdividing the predetermined control range into partial ranges in the control unit. At least one adjustment parameter of the inking unit or the printing press is assigned to each partial range in the control unit. The control unit determines the appropriate partial range as a function of the ink feed selected with the operating element and adjusts the selected ink feed in the inking unit with associated adjustment parameters in the inking unit and/or in the printing press.Type: GrantFiled: February 8, 2011Date of Patent: May 24, 2016Assignee: Heidelberger Druckmaschinen AGInventors: Jürgen Michels, Dieter Schaffrath, Wolfgang Schönberger

Patent number: 8869699Abstract: A method controls a printing speed and a temperature of a printing press to attain a predetermined actuating variable. The printing press includes a control computer. The method is characterized by calculating a target temperature to attain the predetermined actuating variable at a desired printing speed and initiating the adjustment operations to attain the target temperature by the control computer. The actual printing speed is changed via a first acceleration within a tolerance limit with respect to fluctuations about the predetermined actuating variable. The first acceleration process is stopped if the desired printing speed is attained in the process. The first acceleration is changed if the tolerance limits are reached and the desired printing speed has not been attained yet. The printing speed is ran at a modified second acceleration along the tolerance limits until the desired printing speed is attained.Type: GrantFiled: August 3, 2012Date of Patent: October 28, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Peter Elter, Alexander Knabe, Nikolaus Pfeiffer, Wolfgang Schönberger

Patent number: 8567316Abstract: In a method for controlling the temperature of a press which has an applicator roller and a screen roller, the screen roller has its temperature controlled at different temperatures and the applicator roller has its temperature controlled at a constant temperature. In this manner, the choice of the screen roller temperatures can be set individually for each printing unit depending on the optical ink density values which the operator desires.Type: GrantFiled: September 25, 2006Date of Patent: October 29, 2013Assignee: Heidelberger Druckmashinen AktiengesellschaftInventors: Jens Hieronymus, Jürgen Michels, Dieter Schaffrath, Wolfgang Schönberger, Bernhard Schwaab, Michael Thielemann

Patent number: 8511905Abstract: A printing press includes a roller having a first antifriction bearing and a second antifriction bearing. The first antifriction bearing has rolling bodies, a first ring and a second ring. One of the two rings forms an outer ring and the other of the two rings forms an inner ring. Roller sockets are configured as quick action changing devices for receiving the anti-friction bearings during insertion of the roller into the printing press. The first antifriction bearing is configured as an axial floating bearing with a considerable axial movement play of the rolling bodies between the latter and one of the rings. The second antifriction bearing is configured as an axial locating bearing without such a considerable axial movement play. A centering device centers one of the rings relative to the other.Type: GrantFiled: October 8, 2009Date of Patent: August 20, 2013Assignee: Heidelberger Druckmaschinen AGInventors: Jürgen Michels, Roland Müller, Dieter Schaffrath, Wolfgang Schönberger

Patent number: 8499692Abstract: An anilox printing unit includes, as inking unit rolls, an ink applicator roll and an engraved roll mounted in rapid change roll sockets, for removing the engraved roll from the roll sockets and inserting another engraved roll into the roll sockets by an operator. The engraved roll is hollow and a temperature control fluid flows therethrough. The engraved roll and the ink applicator roll each have bearer rings. A device which presses the bearer rings of one inking unit roll against the bearer rings of the other inking unit roll has springs for compensating for diameter differences as a result of manufacturing tolerances between the bearer rings of the engraved roll and the bearer rings of the other engraved roll and for compensating for thermally induced diameter changes of the bearer rings of the engraved roll. A printing press having an anilox printing unit is also provided.Type: GrantFiled: November 20, 2007Date of Patent: August 6, 2013Assignee: Heidelberger Druckmaschinen AGInventors: Gisela Binder, Suat Demir, Jürgen Michels, Ulrich Pföhler, Dieter Schaffrath, Jörg Schilfahrt, Wolfgang Schönberger, Bernhard Schwab, Michael Thielemann

Patent number: 8267387Abstract: A device (1) for the handling of containers with a mandrel (4), the cross-section of which is adjusted to the cross-section of one of the containers to be handled, whereby the mandrel (4) is displaceable, relative to the support device (30), along a direction of movement (L) between a resting position and a working position. The device has a spacing element (10) which is displaceable relative to the mandrel (4) in a direction of displacement (R) between at least two positions, whereby the direction of displacement (R) and the direction of movement form an angle with one another that differs by 0°, and whereby this spacing element is constructed in such a manner that the working position of the mandrel (4) in the direction of movement (L) is changed through a shifting of the spacing element.Type: GrantFiled: March 12, 2008Date of Patent: September 18, 2012Assignee: Krones AGInventors: Christian Stoiber, Wolfgang Schonberger, Gerhard Schwod

Patent number: 8205550Abstract: A method of operating an anilox printing unit in which ink accumulates on and detaches from a feed blade and, after detaching from the feed blade, forms ink accumulations on a screen roller, and in which a gap is formed between the screen roller and a further roller for the ink accumulations to pass through the gap without contacting the further roller, includes forming the gap by displacing the axis of the further roller and evening out the ink accumulations on the screen roller to such an extent that the ink accumulations that have been evened out pass the gap without contacting the further roller. A smoothing roller, for example, may be used to even out the ink accumulations. A printing press for carrying out the method is also provided.Type: GrantFiled: December 5, 2007Date of Patent: June 26, 2012Assignee: Heidelberger Druckmaschinen AGInventors: Gisela Binder, Suat Demir, Jürgen Michels, Dieter Schaffrath, Jörg Schilfahrt, Wolfgang Schönberger, Bernhard Schwaab, Michael Thielemenann
