Patent number: 9937734Abstract: A method for the indirect application of printing liquid onto a printing material provides an intermediate carrier, preferably a circulating belt, a liquid conditioning medium including a first substance applied onto the intermediate carrier and a printing liquid, in particular an inkjet ink, including a second substance applied onto the conditioning medium on the intermediate carrier. The printing liquid is situated as droplets or a layer substantially on the conditioning medium and the droplets or the layer form a contact region on their underside with the conditioning medium. The printing liquid is heated, preferably by way of a dryer and the printing liquid is transferred from the intermediate carrier onto the printing material.Type: GrantFiled: February 18, 2016Date of Patent: April 10, 2018Assignee: Heidelberger Druckmaschinen AGInventors: Bernard Beier, Martin Greive, Peter Hachmann, Axel Hauck, Rolf Kuendgen, Albert Maul, Rolf Mueller, Heiner Pitz, Achim Scheurer, Matthias Schloerholz, Michael Schwandt

Publication number: 20170341418Abstract: A method for manufacturing printed products contains the steps of applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process. An essentially colorless and water-containing liquid is applied a) to non-image regions and/or b) to image regions that have only little ink in the drop-on-demand process. The printing material is dried. The printing material has a coating that contains at least one acid. After the application of ink and the application of a liquid, a water-containing further liquid, for instance a varnish, is applied both to image regions and to non-image regions of the printing material, and that the liquid and/or the further liquid contains at least one substance that at least partly neutralizes the acid. The undesired formation of waves and glossiness fluctuations between varnished image regions and varnished non-image regions may thus advantageously be avoided.Type: ApplicationFiled: May 25, 2017Publication date: November 30, 2017Inventors: THOMAS PAUL, PETER HACHMANN

Publication number: 20170341419Abstract: A printed product is produced by applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process, applying a substantially colorless and water-containing liquid a) to non-image regions and/or b) to image regions that have little ink in a drop-on-demand process and drying the printing material. In this case, the printing material has a coating with at least one acid. After applying ink and applying the liquid, a water-containing further liquid is applied both to image regions and to non-image regions of the printing material. The first-mentioned liquid and/or the further liquid contains at least one substance for at least partly neutralizing the acid. The undesired formation of crease waves or curls and glossiness fluctuations between varnished image areas and varnished non-image areas is thus advantageously avoided.Type: ApplicationFiled: May 25, 2017Publication date: November 30, 2017Inventors: PETER HACHMANN, BERND SITZMANN, YASUHITO OSHIMA, JUN YAMANOBE

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: 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

Patent number: 7478807Abstract: A method for conveying a sheet includes guiding an electrically charged sheet pneumatically along a desired path, continuously detecting a charge distribution on the sheet, and reducing a positional deviation of the sheet from the desired path by actuating at least one actuating element influencing the position in dependence on the charge distribution. An apparatus for conveying a sheet includes a control device for the position of the sheet and a sensor connected to the control device for detecting an electric field present on the sheet. The method and apparatus permit the sheet to be guided with small deviations from the desired path.Type: GrantFiled: August 15, 2006Date of Patent: January 20, 2009Assignee: Heidelberger Druckmaschinen AGInventors: Andreas Detloff, Bernhard Falk, Michael Füner, Peter Hachmann, Johann Schunn, Peter Thoma

Patent number: 7464929Abstract: An apparatus for carrying or guiding a printing material sheet on an air cushion between a nozzle surface and the printing material sheet. The apparatus has first nozzle pairs which are arranged in a first row and second nozzle pairs which are arranged in a second row for generating the air cushion. The first nozzle pairs and the second nozzle pairs in each case have a blower nozzle and a suction nozzle, which are paired in such a way that one and the same air flow is blown out by the respective blower nozzle and is aspirated, at least predominantly, by the suction nozzle that is paired with the blower nozzle. The suction nozzles of the first nozzle pairs are arranged in such a way between the blower nozzles of the second nozzle pairs and the suction nozzles of the second nozzle pairs such that the air flows of the second nozzle pairs flow past the suction nozzles of the first nozzle pairs.Type: GrantFiled: February 13, 2006Date of Patent: December 16, 2008Assignee: Heidelberger Druckmaschinen AGInventor: Peter Hachmann
