Patent number: 6354213Abstract: An apparatus and method for cleaning a metering roll having a composite sleeve or a metal core with a ceramic coating involves the use of a laser. The roll's ceramic coating is covered with a matrix of cells that can get plugged with a polymeric contaminant, such as dried ink.

The laser applies heat to each cell at a temperature that destroys the contaminant, yet leaves the ceramic coating intact. The heat is rapidly delivered and rapidly removed from the roll to minimize the amount of heat conducted to the roll's metal core. In addition, a special pneumatic guide bearing makes it possible to clean the metering roll while it is still in the printing press.Type: GrantFiled: April 3, 2000Date of Patent: March 12, 2002Inventor: Jerome D.

Patent number: 6349643Abstract: Method of influencing ink-trapping behavior of ink-conducting components of a printing unit in a rotary printing press includes disconnecting at a clutch location an inking-unit drive coming from printing-unit cylinders, directly imaging a printing form on a printing-form cylinder within the rotary printing press, and reestablishing the drive connection between the inking unit and the printing-unit cylinders at the clutch location after completing the direct imaging of the printing form; and device for performing the method.Type: GrantFiled: April 29, 1996Date of Patent: February 26, 2002Assignee: Heidelberger DruckmaschinenInventors: Geoffrey Loftus, Gotthard Schmid, Klaus Sauer

Publication number: 20020007752Abstract: A fixing roller and a pressure roller form a nip therebetween to fix a recorded image onto a recording sheet provided into the nip. A coil provides alternating magnetic field with respect to the fixing roller to inductively heat the fixing roller. The coil includes a plurality of coil segments arranged in an axial direction of the fixing roller. The coil segments are connected in a manner of either forward connection or alternate connection. A controller determines either the forward connection or the alternate connection such that an heating efficiency due to the induction heating has a larger value.Type: ApplicationFiled: February 22, 2001Publication date: January 24, 2002Inventor: Yusuke Sakagami

Patent number: 6332941Abstract: Images are impressed on the surface of plastic tiles by a sublimation process. A tile having top and bottom surfaces is placed in a heating press having top and bottom platens. A transfer medium with a printed image thereon is placed in contact with the top surface of the tile. The tile is heated to a temperature sufficient to sublimate the dye and transfer the image onto the top surface of the tile. Heat is applied from both the top and bottom of the tile to prevent warping of the tile. The heat applied to the bottom of the tile is preferably slightly greater than the heat applied to the top of the tile.Type: GrantFiled: October 4, 1999Date of Patent: December 25, 2001Assignee: Invincible Products, Inc.Inventors: Walter S. Council, Carl W. Regutti, H. Leigh Ballance, Jr.

Patent number: 6295928Abstract: A printer includes a printer carrier having a surface for receiving ink for transfer printing onto a carrier material, such as paper. Areas of the surface print carrier are ink attracting and others are made ink repelling. The ink repelling areas are formed by providing the surface with a layer of a substance in a solid phase, such as water in the form of ice. The ice layer repels the ink as it is applied so that the ink is only held on the surface of the print carrier at the areas that are ice free. The ice layer is formed by cooling the surface using a cooling mechanism to form a coating of frost due to condensation. A surface tension reducer for water is coated on the surface prior to cooling the surface. A laser or other radiation emitter structures the ice layer to form the print image.Type: GrantFiled: September 20, 1999Date of Patent: October 2, 2001Assignee: Océ Printing Systems GmbHInventors: Joachim Heinzl, Robert Link

Patent number: 6293199Abstract: A printing press liquid circulation system including a cooling pan having a dedicated power return drain having a power drain orifice and optional cooling capacity located on and as part of the pan. The system induces or suctions flow of liquid from the pan, having a pan supply orifice, to a reservoir through a return conduit by connecting the return conduit to a power return drain. Proper design of the power drain orifice and the pan supply orifice allows for a matched pan supply and return system for an open hydraulic circuit, free of foam and flooding with no adjustments required.Type: GrantFiled: July 7, 2000Date of Patent: September 25, 2001Assignee: Baldwin GraphicsSystems, Inc.Inventors: Charles R. Gasparrini, Christopher Hickey

Patent number: 6284339Abstract: A printing composition that is adapted for printing on computer printers and the like. The printing composition includes a backing sheet and a printing sheet. The printing sheet includes an electret which is reversibly bound to the backing sheet. In one embodiment of the invention, the printing sheet is coated with an ink absorbing coating. The electret can be constructed from materials such as polypropylene or polyethylene that have been subjected to electrostatic fields.Type: GrantFiled: December 9, 1997Date of Patent: September 4, 2001Assignee: Permacharge CorporationInventors: Jack E. Floegel, Calvin Ward

Patent number: 6230623Abstract: A printing machine includes at least one object support rotatably mounted on a conveyor which advances stepwise, at least one radiation type drying oven in vertical alignment with the path of movement of the object support and a drive system for driving a rotation cycle of the object support in line with the drying oven when the conveyor is stopped. The drive system modulates the rotation speed of the object support during the rotation cycle as a function of its angular orientation.Type: GrantFiled: January 7, 2000Date of Patent: May 15, 2001Assignee: Societe d'Exploitation des Machines Debuit, a “Societe Anonyme”Inventor: Jean-Louis Dubuit
