Patent number: 7421948Abstract: An adjustment of a transfer of printing ink is accomplished by arranging a first roller in an inker unit and by using that first roller to transfer ink to a forme cylinder. A temperature is adjusted on an outer surface of the first roller by the use of a first temperature control unit which includes an adjuster device. The adjuster device also adjusts a temperature to be set on an outer surface of the forme cylinder by the use of a second temperature control unit. These two temperature control units adjust parameters of the printing ink through the controls of the outer surfaces of their associated first roller and forme cylinders. The parameters of the printing ink which are adjusted are preferably the ink's tackiness and its viscosity.Type: GrantFiled: May 18, 2005Date of Patent: September 9, 2008Assignee: Koenig & Bauer AktiengesellscahftInventors: Georg Schneider, Wolfgang Otto Reder

Patent number: 7261034Abstract: A method for operating a printing group and a device for the use of a printing ink in a rotary printing press is disclosed. The tack of an ink that is used in a printing group of a rotating printing press, or the temperature of a rotating component in the printing group is selected or controlled.

Patent number: 7124683Abstract: A pressure force exerted by first and second cylinders upon at least a third cylinder in a printing machine is regulated by a pressure regulating device. The device can also be using for moving a first cylinder and at least one second cylinder into and out of contact with a third cylinder. Actuators, which exert a radial force on a cylinder cooperating with the actuators, are provided. An aperture angle between the radial forces exerted by two actuators on the same cylinder is the same in both cylinders. That aperture angle is independent of an aperture angle formed by the pressure force exerted by the first and second cylinders on the third cylinder.Type: GrantFiled: September 21, 2002Date of Patent: October 24, 2006Assignee: Koenig & Bauer AktiengesellschaftInventors: Bernd Klaus Faist, Wolfgang Otto Reder, Georg Schneider

Patent number: 7117792Abstract: The forces exerted by actuators are detected and devices are provided, which use those detected forces to regulate a pressure force exerted by one cylinder against another cylinder in a printing machine. The several forces can also be used for placing or removing one cylinder with respect to another cylinder. One cylinder may be mounted in a cylinder holder which is, in turn, mounted in a frame holder. At least two actuators are arranged between the cylinder holder and the frame holder. These actuators exert a radially directed force against the cylinder holder when they are actuated by a control signal.Type: GrantFiled: September 21, 2002Date of Patent: October 10, 2006Assignee: Koenig & Bauer AktiengesellschaftInventors: Bernd Klaus Faist, Wolfgang Otto Reder, Georg Schneider
