Patent number: 7796042Abstract: The aim of the invention is to simplify the attachment of RFID chips or RFID transponders to packagings. For this purpose, the RFID chips are produced as a single RFID label together with antenna elements that are functionally associated therewith. The chips or transponders can be attached to a packaging by means of corresponding devices during production of the printed material, during a subsequent treatment or finishing process of the printed material, during the preparation of the packaging, during production of the packaging or during filling of the packaging. At the time of attachment, the RFID chips can be tested and initialized. The invention allows to considerably simplify the so far complex processes required to integrate the RFID chips into different types of packaging.Type: GrantFiled: June 14, 2006Date of Patent: September 14, 2010Assignee: MAN Roland Druckmaschinen AGInventors: Thomas Walther, Reinhard Baumann, Robert Weiss, Peer Dilling

Patent number: 7750920Abstract: A method and apparatus for generating a color reference for an image to be printed for visualizing the same on a true-color monitor is disclosed. Lower-resolution image data are generated from high-resolution raster data for the image to be printed which are obtained from page description data for the image to be printed. The lower-resolution data are converted into display data which serve as color reference for the image to be printed and which can be visualized on a true-color monitor. An actual transmission characteristic is ascertained. The actual transmission characteristic ascertained is compared with a specified (desired) transmission characteristic, where, on the basis of this comparison, a correction curve is calculated which is required to arrive at the desired transmission characteristic starting with the actual transmission characteristic. The display data are ascertained using the calculated correction curve.Type: GrantFiled: July 16, 2007Date of Patent: July 6, 2010Assignee: Man Roland Druckmaschinen AGInventor: Florian Fejfar

Patent number: 7744086Abstract: During the transport of flat products, in particular folded products which are transferred at the end of a transport path to an assembly which forwards them, a great degree of freedom from faults can be attained by the fact that, in the case of lower transport speeds, the products are accelerated during the transfer by air which passes along them at a higher speed in the transport direction than the transport speed. In the case of higher transport speeds, the products are expediently braked during the transfer by reducing the pressure in the gap between one of their surfaces and an adjacent guide surface.Type: GrantFiled: November 4, 2005Date of Patent: June 29, 2010Assignee: MAN Roland Druckmaschinen AGInventors: Siegmund Echerer, Hubert Schalk, Christian Winterholler

Patent number: 7707002Abstract: The present invention concerns measures for the space-optimized determination of printing-related measured values. With the aid of a tone value and/or color gradient in a control patch and a suitable measuring device, it is possible to obtain, in a smaller amount of space, adequate or even detailed information about the printing process. Correcting values necessary for the automatic control of the printing operation can be determined on the basis of the information thus obtained, which can be also be continuously acquired due to the space-optimized tone value and/or color gradients.Type: GrantFiled: December 19, 2006Date of Patent: April 27, 2010Assignee: MAN Roland Druckmaschinen AGInventors: Florian Fejfar, Armin Weichmann

Patent number: 7695422Abstract: A folding drum and method of operation is disclosed. The folding drum is used for folding material, in particular for a printing press. The folding drum is mounted rotatably on its longitudinal axle. The folding drum has a folding-blade spindle, the longitudinal axle of which is coupled to the longitudinal axle of the folding drum and is spaced apart from the longitudinal axle of the folding drum. Furthermore, the folding drum comprises a force generation means for generating a relief force which is opposed to a centrifugal force which is generated in the case of a rotating folding drum by the co-rotating folding-blade spindle. Thus, the disadvantageous influence of the centrifugal force can be reduced. As a result, in particular, a mounting of the folding-blade spindle can be relieved. The wear of the mounting can be reduced and its service life can be increased.Type: GrantFiled: November 3, 2006Date of Patent: April 13, 2010Assignee: Man Roland Druckmaschinen AGInventor: Frank Schmieder

Publication number: 20100071575Abstract: A printing unit having a press unit is disclosed. Damping solution is applied to a form cylinder by way of direct damping-solution supply via a damping unit in such a way that a damping-solution applicator roll which is set away from an ink distributor roll and is driven by way of friction by the form cylinder rolls only on the form cylinder and thus applies the damping solution to the form cylinder only directly via the damping-solution applicator roll. In the event of indirect damping-solution supply in which the damping-solution applicator roll rolls exclusively on the ink distributor roll and is driven by way of friction by the ink distributor roll, in order to switch over to direct damping-solution supply, the damping-solution applicator roll is set away from the ink distributor roll more quickly than the damping unit, and thus the damping-solution applicator roll, is set against the form cylinder.Type: ApplicationFiled: September 18, 2009Publication date: March 25, 2010Applicant: MAN Roland Druckmaschinen AGInventors: Anton Stadlmair, Helmut Stuhlmiller

Publication number: 20100027851Abstract: A system and method records and identifies certain attributes of printed products for verifying their authentication and for tracking individual printed products or copies of printed products. In embodiment of the invention, a static code with redundant information and with high spatial resolution is applied on the printed product and the optoelectronic detection of the printed image on the printed product is carried out by means of a line-scan or area-scan camera or a laser scanner within a printing machine or an additional processing machine. The data are decoded after their acquisition by means of the optoelectronic detection device and the decoded data are used for characterizing an individual printed image and/or the printing process.Type: ApplicationFiled: October 19, 2007Publication date: February 4, 2010Applicant: MAN ROLAND DRUCKMASCHINEN AGInventors: Thomas Walther, Bernhard Wirnitzer

Patent number: 7654428Abstract: A turner bar for a rotary press for deflecting a substrate web in two web running directions is acted upon by pressurized air. The turner bar includes at least one inner tube and one outer tube, which have air discharge holes assigned to one another to produce an air cushion above the turner bar. The inner tube can be adjusted relative to the outer tube, so that the air discharge holes can be closed in such a way that the air cushion is adapted to the margins of the substrate web. It is thus possible to use the turner bar in both web running directions.Type: GrantFiled: March 23, 2007Date of Patent: February 2, 2010Assignee: MAN Roland Druckmaschinen AGInventors: Johannes Behmel, Andrea Schädlich

Patent number: 7647845Abstract: A device and method for determining the web tension or the web tensile force in a printing substrate web is disclosed. A device is arranged at a first position along a transport path of the printing substrate web, which device supplies a signal to deduce the web tension in effect at the first position or the web tensile force in effect at the first position. A device arithmetically determines the web tension in effect or the web tensile force in effect at the second position from the web tension in effect at the first position or from the web tensile force in effect at the first position as well as from forces, which at least one driven roller and/or at least one trailing roller, which is/are arranged along the transport path of the printing substrate web between the first position and the second position, introduce to the printing substrate web.Type: GrantFiled: March 28, 2008Date of Patent: January 19, 2010Assignee: MAN Roland Druckmaschinen AGInventor: Wolfgang Hiesinger
