Patent number: 10838344Abstract: Certain examples described herein relate to splice detection. In certain cases, a splice is detected in a web being conveyed towards a transfer member of the printing system. In certain cases, a print frame is identified from a sequence of pending print frames using successive repeat lengths of the sequence and a distance of the splice from the transfer member. The identified print frame is to be transferred from the transfer member across the splice.

Publication number: 20110259221Abstract: The present invention relates to a flexographic method of printing and a flexographic printing apparatus whereby the repeat length is greater than the circumference of the printing roller. This may be achieved by controlling the rotation of the printing roller as a non-printing zone of the printing roller passes a moving web such that an associated non-printed region formed on the web has a length that is greater than the non-printing zone. The rotation of the printing roller may be controlled by suspending the rotation of the printing roller or reducing the speed of rotation when the non-printing zone is in registration with the web and then increasing the speed of rotation to a predetermined printing speed as a printing zone of the printing roller comes into registration with the web.Type: ApplicationFiled: January 12, 2010Publication date: October 27, 2011Inventors: Colin Hargreaves, David Hargreaves

Publication number: 20110209638Abstract: A superstructure of a printing press includes a turning tower with at least one turner bar that is usable to deflect a web section from a transport direction by 90°. A second turner bar, that is shorter than the first turner bar, is also used to deflect a web section from the transport direction by 90° in the same direction as the first web section. These first and second turner bars are offset vertically in relation to one another in the same turning tower. The first turner bar is supported at both ends on at least one first lateral support and at least one second lateral support. The second turner bar is supported only on one end on the lateral support in a floating manner. The second support side of the second turner bar is provided with access from that support side into the interior of the turning tower.Type: ApplicationFiled: October 15, 2009Publication date: September 1, 2011Inventor: Burkard Otto Herbert

Patent number: 7975610Abstract: The invention relates to a printing unit (16; 17) comprising several printing groups (03; 04; 21; 22; 28; 29; 31; 32), each of which is provided with at least one plate cylinder (07) and at least one transfer cylinder (06) that is arranged so as to cooperate directly with the plate cylinder (07). The printing unit (16; 17), which is embodied as a nine-cylinder satellite printing unit (16; 17), is equipped with four plate cylinders (07) and a counterpressure cylinder (18) that is configured as a satellite cylinder (18). At least one inking roller of an inking group (09) is disposed so as to cooperate directly with the plate cylinder (07). One respective plate replacing mechanism (11; 11a; 11b), which encompasses a front section facing the associated plate cylinder (07), is assigned to at least two plate cylinders (07) that are placed next to each other in a horizontal direction.Type: GrantFiled: January 24, 2007Date of Patent: July 12, 2011Assignee: Koenig & Bauer AktiengesellschaftInventor: Jürgen Alfred Stiel

Publication number: 20110162545Abstract: A printing unit is comprised at least of a plurality of printing machines which are arranged on the same side of a web to be printed. Each such printing machine includes an inking unit having at least one roller, and a dampening unit. Rollers of the inking units of several of the printing machines, which are arrayed on the same side of the web to be printed, are in thermal contact with the same temperature-control medium unit for controlling the temperature of the rollers. The temperature control medium circuit is configured as an inner temperature-control medium circuit having substantially constant circulating volumetric flow rate of a temperature-control medium.Type: ApplicationFiled: September 4, 2009Publication date: July 7, 2011Inventor: Claus August Bolza-Schünemann

Publication number: 20110146511Abstract: A printing unit for printing a web of paper is provided. The printing unit includes a frame and an upper printing group and a lower printing group. The printing unit has at least one throw-on configuration and a blanket-changing throw-off configuration. The blanket cylinders are capable of each receiving at least one tubular blanket. The frame has, in at least one lateral wall, at least one opening to allow the passage of the tubular blankets. In the blanket-changing throw-off configuration, the blanket cylinder of the upper printing group has been moved upwards relative to the position which it occupies in the throw-on configuration and the blanket cylinder of the lower printing group has been moved downwards relative to the position which it occupies in the throw-on configuration, so that an adequate space is provided between the blanket cylinders to allow a web of paper printed by another printing unit to pass between them.Type: ApplicationFiled: March 4, 2011Publication date: June 23, 2011Applicant: GOSS INTERNATIONAL MONTATAIRE SAInventors: Patrick Menu, Francois Recolet

Patent number: 7958821Abstract: A printing unit of a printing machine is supported by a pair of spaced side frames that are disposed opposite to each other. The printing unit includes at least one printing machine and at least one ink unit. The printing machine is formed by a plurality of printing cylinders. Each of the spaced side frames include a longitudinal crossbar that runs in the direction of transfer of a print substrate traveling through the printing unit. The two longitudinal crossbars form the boundaries of a foot space of the printing unit at two parallel sides. A plurality of pipelines are disposed in the foot space between the two longitudinal crossbars. These pipelines supply flowable media to the printing unit, which flowable media can be either liquid or gaseous. At least one of the pipelines is connected to a user of one of the supplied flowable media in the printing unit or to at least one source of the flowable media. The printing machine can utilize a plurality of printing units.Type: GrantFiled: March 11, 2009Date of Patent: June 14, 2011Assignee: Koenig & Bauer AktiengesellschaftInventors: Andreas Kümmet, Werner Ludwig Fischer, Uwe Alexander Reuter

Patent number: 7886663Abstract: Vibrations of a cylinder, which is a part of a web-processing machine, and particularly a printing machine, are dampened. A functional correlation is determined for a course of a force of a channel passage through a nip point defined by the cylinder and a second cylinder. The functional correlation is pre-defined up to a scaling factor determining the height as a time course for an actuator force time course and is stored in a control or a regulating device. The vibration, or an amplitude of the vibration is measured during the operation of at least part of the cylinder by the use of a sensor. A maximum vibration amplitude on the roll body of the cylinder is then calculated from the measuring value. The actuators are controlled by the control or regulating device according to the pre-defined actuator force time course.Type: GrantFiled: December 9, 2005Date of Patent: February 15, 2011Assignee: Koenig & Bauer AktiengesellschaftInventors: Ralf Christel, Oliver Frank Hahn, Karl Erich Albert Schaschek
