Publication number: 20130337232Abstract: The invention relates to a method for producing interior lining parts in a foaming tool, to an interior lining part produced accordingly, and to a foaming tool which can be used for production. The interior lining part has at least one molded skin, at least one foam layer and at least one carrier, the foam layer being located between the molded skin and the carrier. In order to produce an interior lining part according to the invention, the molded skin is introduced into a mold of a foaming tool. The foaming tool contains at least one separating edge. During back-foaming, the carrier is pressed against the molded skin at the position of the separating edge and connected to said molded skin such that a molded skin end can be severed manually, that is without the aid of tools, from the molded skin or is severed by the pressing step.Type: ApplicationFiled: February 3, 2012Publication date: December 19, 2013Applicant: Faurcia Innenraum Systeme GmbHInventors: Axel Hauck, Bernd Keller

Patent number: 8037816Abstract: A measurement field allows determining the smearing limit during printing, in particular during lithographic wet offset printing. The measurement field is arranged on a printing form, in particular a printing plate, which has printing, ink-carrying regions and nonprinting, dampening solution-carrying regions on its surface. A dampening solution-carrying property in the region of the measurement field is reduced by a nanoscopic coating (e.g., with amphiphilic molecules) or an unscreened, microscopic coating (e.g., a polymer coating) in comparison with the dampening solution-carrying property in the nonprinting regions of the surface of the printing form. The nanoscopic coating or the microscopic coating advantageously leads to a shifting of the smearing limit, that is to say to a displacement of the starting point of scumming, by the dampening solution requirement which is increased for scum-free printing within the region of the measurement field.Type: GrantFiled: June 27, 2008Date of Patent: October 18, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Martin Gutfleisch, Axel Hauck

Patent number: 7913622Abstract: A method for drying a printing ink (114) on a printing substrate (14) in a printing press (30), and a printing press (30). The printing substrate (14) is moved along a path (16) through the printing press (30) and printed on by at least one printing ink (114) at a first position (18) of the path (16). At a second position (124) of the path (16), in a conditioning apparatus, a treatment agent (118) is applied to the printing substrate (14) to accelerate the drying of the printing ink (114) on the printing substrate (14) and includes, in particular, an infrared absorber which has an absorption wavelength that is essentially resonant to the wavelength of the light (12) of the radiant energy source (10). The printing substrate (14) may be dried by the action of radiant energy at a chronologically later point in time, at at least one third position (116) of the path (16), by a drying device, in particular by a narrow-band radiant energy source (10).Type: GrantFiled: August 4, 2008Date of Patent: March 29, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Heiner Pitz, Axel Hauck, Werner Anweiler, Peter Hachmann

Publication number: 20100000430Abstract: An offset printing process is carried out in an offset printing unit. Offset printing ink pre-emulsified with a dampening solution is supplied to the offset printing unit through an ink metering device and further dampening solution is supplied in the offset printing unit. The offset printing ink is applied to a printing form with at least one ink applicator roller and a printing material is printed with the offset printing ink. In this way, a subject-independent, constant margin from the smearing limit for offset printing is obtained.Type: ApplicationFiled: July 2, 2009Publication date: January 7, 2010Applicant: HEIDELBERGER DRUCKMASCHINEN AKTIENGESELLSCHAFTInventor: Axel Hauck

Patent number: 6899031Abstract: A method is known of compensating for misregistration during operation of a printing press, in particular a sheet-fed offset printing press, in which misregistration occurring in the individual printing units are countered by register corrections. In order to provide a simple method to reduce misregisters after a pause in printing and in particular after washing of the rubber blanket cylinder, the pattern of the misregistration (PD) after a pause in printing is determined in a calibration phase over a sufficient number of sheets, data as a function of the pattern of the misregistration is stored in a memory unit (15) so that register correction values (Ki) may be determined and the register correction values are applied to the printing press upon restart after the pause in printing in order to compensate for the misregistration.Type: GrantFiled: September 12, 2003Date of Patent: May 31, 2005Assignee: Heidelberger Druckmaschinen AGInventor: Axel Hauck

Patent number: 6694883Abstract: First, the inking behavior of the printing units of a multicolor rotary printing machine is determined by means of test forms. The inking nonuniformities on the test forms are transmitted to the pre-press stage. Using the data about the inking nonuniformities of the test forms, the raster tonal values of the color separations of a printing form are modified in such a way that the inking nonuniformities are compensated locally on the basis of the location of their occurrence in the print on the printing forms or films.Type: GrantFiled: August 31, 2001Date of Patent: February 24, 2004Assignee: Heidelberger Druckmaschinen AGInventor: Axel Hauck

Patent number: 6679169Abstract: The present invention relates to a method for controlling the ink feed in a printing press which processes printing substrates (12) and features at least one inking unit and one computer and to a device for carrying out the method. The present invention is characterized in that the computer knows at least the physical properties of printing ink and/or printing substrates (12) as data, that the stored data is read into an ink control model which is stored in the computer, and that the optimum settings with regard to the ink feed are made on the basis of this ink control model before the start of printing or during the printing process.Type: GrantFiled: October 24, 2002Date of Patent: January 20, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Werner Anweiler, Caroline Gateaud, Axel Hauck, Martin Mayer

Patent number: 6655272Abstract: The method effects a closed-loop control of the quantity of dampening solution during printing. The metering of the quantity of dampening solution to be applied to the printing material is preferably a function of the printing speed. In addition, at least one of the variables that influence the requisite quantity of dampening solution in the printing process is taken into account.Type: GrantFiled: November 26, 2001Date of Patent: December 2, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Axel Hauck, Nikolaus Pfeiffer

Patent number: 6637337Abstract: A method for controlling the temperature of print bearer surfaces during printing in rotary printing machines. The print bearers are fastened in exchangeable fashion on the circumferential surface of print form cylinders. The surfaces of the print bearers are inked by inking form rollers. The temperature of the color-separation-guiding surfaces of the print bearers is controlled in such a way that narrower/broader printing and/or shorter/longer printing arising during the passage of the printed material through the printing unit is compensated per individual printing unit.Type: GrantFiled: August 23, 2001Date of Patent: October 28, 2003Assignee: Heidelberger Druckmaschinen AGInventor: Axel Hauck
