20080276816 | Method for Automatically Adjusting Pressure Between Rotary Bodies in a Printing Press and Printing Press for Carrying out the Method - A method for automatically adjusting a pressure between rotary bodies in a printing press, includes measuring an image of a pressure strip on printing material. An image of a first pressure strip formed by a first rotary body together with a second body and an image of a second pressure strip formed by the second rotary body together with a third rotary body, are measured on the printing material. A printing press for carrying out the method is also provided. | 11-13-2008 |
20080289523 | Anilox Printing Unit and Printing Press Having an Anilox Printing Unit - 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. | 11-27-2008 |
20090078136 | Printing Press with Bearer Rings - A printing press includes a first rotary body with a first bearer ring and a second rotary body with an axle which eccentrically supports a second bearer ring. The second bearer ring is in rolling contact with the first bearer ring and is rotatably coupled to the second rotary body. | 03-26-2009 |
20090193988 | Printing Press Having an Anilox Inking Unit with an Associated Washing Device - A printing press includes an anilox inking unit having an engraved roller and a washing device with a feed device for introducing detergent and a removal device for removing the detergent and printing ink. Further rollers are disposed between the feed device and the engraved roller and between the engraved roller and the removal device, as viewed in a conveying direction of the detergent. An effective length of the further rollers increases from the feed device to the removal device. | 08-06-2009 |
20100083857 | Printing Press - 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. | 04-08-2010 |
20110132214 | PRINTING UNIT - A printing unit contains a dampening unit and an inking unit which includes a screen roller with a circumference and an ink applicator roller with a circumference and a gap having an arc length or curve length, the ink applicator roller resting against the screen roller. The circumference of the screen roller and the circumference of the ink applicator roller and the arc length or curve length of the gap are dimensioned in predetermined proportions relative to each other so as to avoid ghosting. | 06-09-2011 |
20110192305 | INK CONTROL METHOD FOR PRINTING PRESSES HAVING SHORT INKING UNITS - 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. | 08-11-2011 |
20140283705 | METHOD FOR CLEANING AN ANILOX PRINTING UNIT - A method for cleaning an anilox printing unit includes a first process step and a second process step immediately following the first process step without any intermediate printing operation. In the first process step, printing ink is supplied to a screen roller from a blade-type ink fountain while an ink applicator roller is in contact with the screen roller and out of contact with a bridge roller of a dampening unit. In the second process step, printing ink is removed from the screen roller and returned into the same blade-type ink fountain while the ink applicator roller is engaged with the screen roller and with the bridge roller. | 09-25-2014 |

20080308191 | Process For Melt Dip Coating a Strip of High-Tensile Steel - A process for melt dip coating a strip of high-tensile steel with alloy constituents including zinc and/or aluminum includes the following steps. The strip is heated in a continuous furnace initially in a reductive atmosphere to a temperature of approximately 650° C., at which the alloy constituents diffuse to the surface in small amounts. The surface, consisting predominantly of pure iron, is converted into an iron oxide layer by a short heat treatment at a temperature of up to 750° C. in a reaction chamber which is integrated in a continuous furnace and has an oxidizing atmosphere. In a subsequent annealing treatment at a higher temperature in a reductive atmosphere, this iron oxide layer prevents the alloy constituents from diffusing to the surface. In the reductive atmosphere, the iron oxide layer is converted into a pure iron layer to which the zinc and/or aluminium are applied in the molten bath with optimum adhesion. | 12-18-2008 |
20090199931 | Method for Melt Immersion Coating of a Flat Steel Product Made of High Strength Steel - A method for coating a flat steel product manufactured from a high strength steel with a metallic coating, wherein the flat steel product is initially subjected to a heat treatment, in order then, in the heated state, to be hot-dip galvanized with the metallic coating in a melting bath containing overall at least 85% zinc and/or aluminum. The heat treatment includes heating the steel product in a reducing atmosphere, followed by converting a surface of the flat product to an iron oxide layer by a heat treatment lasting 1 to 10 secs in an oxidizing atmosphere, followed by annealing in a reducing atmosphere over a period of time which is longer than the duration of the formation of the iron oxide layer such that the iron oxide layer is reduced at least on its surface to pure iron, followed by cooling the product to a melting bath temperature. | 08-13-2009 |
