Patent number: 8800445Abstract: A printing plate cylinder for a printing machine has a rotatable cylinder mandrel and a sleeve that is at least partially positionable over the cylinder mandrel. The angular positions of the mandrel and the sleeve are alignable to each other by a male register element which is fixed on one of the two elements to be aligned, and a female register element which is part of the corresponding other element to be aligned.

Patent number: 7966935Abstract: A method for registering a rotary press for a printing process, in which “n” inking systems (Fn) each produce monochrome printed images and print one on top of the other thereby producing n-colored printed images, includes producing the images of a printed material with at least one sensor station, recording information on rotary movements of printing plate cylinders (Dn), and using the images and the information to produce correction signals which actuate the cylinders until a deviation of the images of the respective inking systems from a desired position on the material lies within a defined range of tolerance values. During the registering method, one printing plate cylinder at a time is in the printing position, the sensor station produces the printed images, and the correction signals are obtained based on the image produced by the respective cylinder and the information on the rotary movements of at least one cylinder.Type: GrantFiled: January 19, 2006Date of Patent: June 28, 2011Assignee: Windmoeller & Hoelscher KGInventors: Manfred Loddenkoetter, Martin Kruempelmann

Patent number: 7555985Abstract: A method for pre-registration in a printing machine with multiple printing units in which phases of the printing cylinders involved in the printing process are so mutually attuned that the deviations of the printing images of the different printing cylinders lie within mutual capture areas, includes using the deviations in the context of the registration of an ongoing printing operation, respectively, for the determination of the position of the printing images or parts thereof. The web to be printed, which is fed during the pre-registration to the printing machine, has at least one mark, which passes through different printing units during the pre-registration. The time points at which the mark passes the measuring points in the printing units are recorded, and these time points are set with reference to the angular position of the printing images of the respective printing units at those time points.Type: GrantFiled: November 12, 2003Date of Patent: July 7, 2009Assignee: Windmoeller & Hoelscher KGInventor: Manfred Loddenkoetter

Publication number: 20060150852Abstract: Described is a method for pre-registration in a printing machine (1) with multiple printing units (D1-D4). In this method, the phases of the printing cylinders (F1-F4) involved in the printing process are so mutually attuned that the deviations of the printing images of the different printing cylinders (F1-F4) lie within mutual capture areas, which are used in context of the registration of an ongoing printing operation, respectively, for the determination of the position of the printing images or parts thereof.

Patent number: 6715203Abstract: A substrate for power semiconductor modules with a through-plating of solder, includes two metal plates and a ceramic plate which is seated as a layer between the metal plates and has a through hole formed therein. The substrate is plated through by making a through hole in one of the metal plates in alignment with the through hole in the ceramic plate and applying a paste solder to one side of the substrate. The substrate is then subjected to a furnace step, so that the paste solder flows into the through holes and the solder makes a permanent contact between the two metal plates. A method for producing the substrate is also provided.Type: GrantFiled: February 20, 2001Date of Patent: April 6, 2004Assignee: EUPEC Europaeische Gesellschaft fuer Leistungshalbleiter mbH & Co.
