Patent number: 8011411Abstract: For transferring an image-forming layer from a transfer foil a printing sheet, an adhesive layer is first applied to the sheet to be printed. The transfer foil provided with the image-forming layer is guided past the printing sheet under pressure, in a coating module (2), such that the image-forming layer adheres to the adhesive and an image is created. The present invention provides a foil transfer device that includes a substrate on the press cylinder that has a reduced adhesiveness relative to the transfer foil.Type: GrantFiled: April 13, 2005Date of Patent: September 6, 2011Assignee: manroland AGInventors: Hans-Georg Eitel, Rainer Gebhardt, Wolfgang Mexner, Uwe Püschel, Michael Reising, Guido Reschke, Jürgen Schölzig, Michael Zinke

Publication number: 20100147168Abstract: To transfer a coating in image form from a transfer foil to a print sheet, adhesive is applied in the form of the image to said sheet. In a foil transfer module (2), the carrier foil with the coating in image form is then brought into contact with the print sheet using contact pressure, so that the coating adheres to the adhesive pints and an image is produced. To improve the function, simplify the device and increase the flexibility of the method, a transfer cylinder (3) is provided with a covering that has a variable cover thickness (25), in order to adapt the surface speed of the transfer cylinder (3).Type: ApplicationFiled: March 17, 2007Publication date: June 17, 2010Applicant: manroland AGInventors: Uwe Puschel, Jurgen Scholzig, Detlef Krause

Publication number: 20100078121Abstract: In a method for transferring layers from a carrier foil onto printed sheets, an imaging or covering layer is to be transferred from the carrier foil onto the printed sheet in an adhering manner in a sheet processing machine. A more flexible production method is provided in a sheet offset printing machine. To this end, each printed sheet is provided on at least one printed or unprinted first side with a foil coating. Each printed sheet is further turned before or after the coating in the sheet processing machine, and at least printed or coated on the side opposite of the foil coating, and provided with a film coating in a further coating device (2).Type: ApplicationFiled: December 4, 2007Publication date: April 1, 2010Applicant: Man Roland Druckmaschinen AGInventors: Jurgen Scholzig, Uwe Puschel

Publication number: 20100065193Abstract: The aim of the invention is to diversify film coating in a coating station for transferring image-providing layers from a transfer film onto a printing material. For this purpose, a film transfer module is arranged in a printing press for single-color or multicolor printing of printed sheets. One or more devices for producing a surface structure on the printing material are arranged in the printing press upstream of a film transfer module. A design from a film image and a printed image is partially or completely covered by applying layers. The additional layers serve for the protection, for drying and for producing optical effects.Type: ApplicationFiled: December 4, 2007Publication date: March 18, 2010Inventors: Uwe Puschel, Jurgen Scholzig

Publication number: 20080196662Abstract: A device for transferring an image-forming layer from a transfer film to a printing sheet, including an applicator unit for applying a coating of glue in the form of an image to the printing sheet; and a coating unit including an impression cylinder for guiding the printed sheet with the coating of glue facing away from the impression cylinder, and a pressure roller for guiding the transfer film with the image-forming layer facing away from the pressure roller. The impression cylinder and the pressure roller form a transfer gap therebetween so that the transfer film and the printing sheet are pressed against each other when guided through the transfer gap so that the image-forming layer remains adhered to the printing sheet in the area of the coating of glue and is lifted off from the transfer film after leaving the transfer gap. A process is also disclosed.Type: ApplicationFiled: November 14, 2007Publication date: August 21, 2008Applicant: MAN Roland Druckmaschinen AGInventors: Guido Reschke, Jurgen Scholzig, Uwe Puschel, Markus Jung-Diefenbach

Publication number: 20070144661Abstract: The present invention improves the guiding of the transfer film in a coating module for transferring image-forming layers from the transfer film onto a printing sheet. For this purpose, a limited pressing face is arranged in the coating module that allows the film advance to be controlled in a targeted manner. In the coating module, the transfer film can be guided past a portion of the width of a press roll in an approximately tangential manner.Type: ApplicationFiled: December 21, 2006Publication date: June 28, 2007Applicant: MAN Roland Druckmaschinen AGInventors: Uwe Puschel, Jurgen Scholzig

Patent number: 6712002Abstract: A printing machine having an inking unit which prevents overinking of the printing cylinder upon increases in printing speed, such as during start-up of a printing operation. The inking unit includes an ink supply, two roll trains each comprising a plurality of inking rolls for communicating ink from the ink supply to a plurality of ink applicator rolls associated with the printing cylinder, with at least one inking roll in each roll train being displaceable in phase with an increase in printing speed for interrupting the respective roll train and preventing excessive ink application to the printing cylinder.Type: GrantFiled: March 5, 2003Date of Patent: March 30, 2004Assignee: MAN Roland Druckmaschinen AGInventors: Sonke Herbst, Elmar Jung, Uwe Puschel, Peter Schramm

Patent number: 6371024Abstract: The invention relates to a sheet-fed rotary printing machine with printing units for multicolor printing and at least one coating unit. An object of the invention is to provide stable quality during the coating process and to reduce contamination of coating fluids. This is achieved by providing at least one coating unit being arranged downstream of the printing units, the coating unit including a cleaning system. More specifically, each of the coating units has a rotatable applicator roller, a metering system for applying coating fluid to the applicator roller, and a cleaning wiper system which is movable into and out of contact with the applicator roller. The cleaning wiper is arranged upstream of the metering system relative to a direction of rotation of the applicator roller.Type: GrantFiled: October 20, 2000Date of Patent: April 16, 2002Assignee: MAN Roland Druckmaschinen AGInventors: Jurgen Scholzig, Uwe Puschel, Ulrich Jung

Patent number: 5575212Abstract: An apparatus for feeding a printing plate to a printing machine is disclosed. The apparatus of the printing machine includes a guard plate connected to the frame and moveable between a first position which impedes access to the interior of the printing machine and a second position which allows access to the interior of the printing machine. The apparatus further includes a support bracket pivotally connected to the guard plate and articulating means for permitting movement of the support bracket with respect to the guard plate between a first, essentially vertical position supporting the printing plate in a ready position and a second, inclined position for feeding the printing plate to the printing machine.Type: GrantFiled: September 29, 1995Date of Patent: November 19, 1996Assignee: MAN Roland Druckmaschinen AGInventors: Gernot Moser, Uwe Puschel, Hans Stutzer
