Patent number: 6526888Abstract: A method for reducing vibrations in a printing press, the printing press having a first plate cylinder independently registrable from a second print cylinder. The method includes the steps of determining a lateral position of the first vibrator, roll with respect to the second vibrator roll and rotating the first plate cylinder with respect to the second plate cylinder so as to change the lateral position of the first vibrator roll with respect to the second vibrator roll. A printing press has a controller receiving an input from at least one sensor, the controller rotating the first plate cylinder with respect to the second plate cylinder so as to alter a phase between the first vibrator roll and the second vibrator roll as a function of the input.Type: GrantFiled: December 1, 2000Date of Patent: March 4, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Gerald Roger Douillard, Mark Bernard Dumais, Michael Thomas Woroniak

Patent number: 6523468Abstract: Printing material is transported through the multicolor printing machine with a cyclically operating feeding arrangement. At least one surface of the printing material is successively imprinted with a printed image. The printed image is recorded in a image pickup and an image signal of each printed image is generated. The image signal generated from a plurality of printed images is transmitted to a control device. The control device processes the electric image signals to obtain information relating to rhythmic vibrations in the machine causing register deviations. The cause of the vibrations is determined and counter-measures are initiated for minimizing or eliminating the rhythmic vibrations.Type: GrantFiled: September 27, 2000Date of Patent: February 25, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Gerhard Löffler, Axel Hauck

Patent number: 6520080Abstract: A system and method for detecting and diverting sections of web having splices on a continuous web is provided. A splice detector is located adjacent a source of continuous web, typically a roll. The movement of the web from the roll is tracked, and the relative location of the splice within the web stream is noted by a controller. Downstream, a web utilization device is provided with a movement detector also connected to the controller. Movement of the splice-containing section through utilization device is tracked so that the splice-containing section is not processed by the utilization device, or is reprocessed on a non-splice-containing section. A cutter is also provided with a movement detector, also connected to the controller. Movement of the web from the utilization device to the cutter is tracked and the section containing the web is cut. A diversion mechanism can be used to remove the cut section of web containing the splice so that it does not appear in the final stream of finished cut sheets.Type: GrantFiled: December 15, 2000Date of Patent: February 18, 2003Assignee: Roll Systems, Inc.Inventor: Jules M. Fried

Publication number: 20030030543Abstract: A method is disclosed of controlling a proximity transaction between first and second communications devices, each of which is provided with a short-range transceiver. The first communications device has an RF/ID reader, and the second communications device has an RF/ID tag, the RF/ID tag containing the same identifier information as the second communications device. The second communications device is positioned within the range of the reader of the first communications device. Then, the transceiver of the second communications device transmits a transaction request and the identifier information of that device to the first communications device. The reader of the first communications device then interrogates the tag of the second communications device and the transaction is completed upon the reader of the first communications device receiving identifier information from the tag of the second communications device that is identical to the identifier information already received.Type: ApplicationFiled: July 1, 2002Publication date: February 13, 2003Inventors: Robert John Castle, John Deryk Waters

Publication number: 20030019382Abstract: A printing machine provided allows even unskilled operators to perform ink and water supply control according to the contents of an image. While a reference image to be printed is segmented into a plurality of regions similar in contents, image data is obtained from printed matter and a color difference between the reference image and a print image is calculated. Ink and water (I/W) supplies are determined based on regional color difference data obtained by summing the color differences for each region. At this time, by adding correction of the regional color difference data based on the characteristics of each region and the contents of the image, and correction of the I/W supplies based on external factors and variables, even unskilled operators can perform rapid I/W supply control based on the contents of the image.Type: ApplicationFiled: July 24, 2002Publication date: January 30, 2003Applicant: DAINIPPON SCREEN MFG. CO. LTD.Inventor: Itaru Furukawa

Patent number: 6508169Abstract: A compound recording method and compound recording apparatus are provided for producing a printed product. The apparatus includes a plurality of image forming devices to form images on a plurality of recording sheets based on a plurality of image data arbitrarily obtained. Each of the image forming devices forms a separate image on a separate recording sheet in parallel with other image forming devices, and a sheet finisher is provided to accept the plurality of recording sheets ejected from the plurality of image forming devices and apply a designated finish-processing to the plurality of recording sheets on which the images are already formed by the plurality of image forming devices.Type: GrantFiled: July 11, 2000Date of Patent: January 21, 2003Assignee: Konica CorporationInventor: Kazuo Sato
