First the pressure a signal indicative of the pressure between the two print drums is obtained by a measurement unit (930), and then the gap between the drums is automatically adjusted in accordance with the indicator signal by a gap adjuster (940).Type: ApplicationFiled: October 5, 2006Publication date: November 18, 2010Inventors: David Levanon, Ilan Frydman, Yury Alioshin, Shai Lior, Boaz Tagansky

Patent number: 7819060Abstract: The invention provides a method and apparatus for mounting two or more cylindrically-shaped printing forms onto a cylindrically-shaped base. The base can be a print cylinder or an adapter mounted onto a print cylinder. The method and apparatus provide for positioning the two or more printing forms in register on the base. The two or more printing forms are axially oriented on the base using pressurized air as an air cushion between the base and the printing forms, positioned in a registration position, and engaged by a holding member to maintain the two or more printing forms in their respective registration position.Type: GrantFiled: April 13, 2007Date of Patent: October 26, 2010Assignee: E.I. du Pont de Nemours and CompanyInventors: Bradley K. Taylor, Stephan Riechert, Thies Knudsen

Patent number: 7809464Abstract: The invention relates to a registration system for sheet fed processing machines that reduces or eliminates the need to calibrate the register and/or timing dials of such a machine. The system uses known measurements and the elapsed time between electrically generated pulses to determine the relative position of processing cylinders in the machine relative the timing of a feed mechanism. The relative positions are displayed in real-time and can be adjusted by an operator. The machine need not be ‘in time’ to properly register the machine.Type: GrantFiled: March 24, 2006Date of Patent: October 5, 2010Assignee: Mikowen Industries, LLCInventor: Mike Owen

Patent number: 7784402Abstract: A method for aligning the leading edge of printing plate (110) to an axially disposed slot (70) in a cylindrical surface (30) of an imaging drum (20) comprising at least one printing plate clamp (90) having a clamp surface (100) disposed parallel to the slot, the method comprising straightening (210) the leading edge against the clamp surface and positioning (220) the leading edge to protrude over the slot by rotating the imaging drum under the plate. The straightening comprises resting (200) the leading edge of the plate on the cylindrical surface of the imaging drum and rotating the imaging drum about its cylindrical axis (60) to contact with the clamp surface a point along the leading edge of the plate and to rotate the plate until its leading edge is in alignment with the clamp surface.Type: GrantFiled: April 24, 2007Date of Patent: August 31, 2010Assignee: Eastman Kodak CompanyInventors: Calvin D. Cummings, Peter Hawes

Patent number: 7748318Abstract: A multi-color rotary printing machine has one printing plate support assigned to the colors that are transferred onto the print substrate. This printing plate support supports a printing plate and is attached to a mandrel or a cylinder of a rotary printing machine in order to transfer the print image onto the print substrate. The rotary printing machine has register devices that determine the position of the printing plates with respect to one another and that have sensors to determine the positions of the printing plate support in the printing machine.Type: GrantFiled: May 6, 2004Date of Patent: July 6, 2010Assignee: Windmoeller & Hoelscher KGInventors: Martin Kruempelmann, Manfred Loddenkoetter
