Patent number: 8096238Abstract: A satellite printing unit of a web-fed printing press with printing couples is disclosed. Each printing couple includes a plate cylinder and a transfer cylinder where the transfer cylinders of all the printing couples roll off a common impression cylinder. Each plate cylinder features a high lockup slot and a low lockup slot and each transfer cylinder has a lockup slot. The transfer cylinders of the printing couples are aligned relative to the plate cylinders of the printing couples such that, on a first group of printing couples, which includes at least one printing couple, the lockup slot of the respective transfer cylinder rolls over the high lockup slot of the respective plate cylinder and on a second group of printing couples, which includes at least one printing couple, the lockup slot of the respective transfer cylinder rolls over the low lockup slot of the respective plate cylinder.Type: GrantFiled: February 26, 2008Date of Patent: January 17, 2012Assignee: Man Roland Druckmaschinen AGInventors: Marc Rehm, Helmut Stuhlmiller

Patent number: 7938064Abstract: A printing unit of a web-fed rotary press has a plurality of press units, each press unit having a form cylinder, a transfer cylinder, an inking unit and optionally a damping unit, and having at least one impression cylinder. Each form cylinder rolls on the respective transfer cylinder and each transfer cylinder rolling on an impression cylinder in a thrown-on position of the printing unit, in order to apply single-color printed images onto a printing material which is moved through between the transfer cylinders and the or each impression cylinder. Each form cylinder bears a plurality of printing images next to one another in the axial direction, by which corresponding single-color printed images are applied to the printing material.Type: GrantFiled: April 13, 2006Date of Patent: May 10, 2011Assignee: MAN Roland Druckmaschinen AGInventors: Stefan Albrecht, Rainer Burger, Norbert Dylla, Helmut Stuhlmiller

Publication number: 20100071575Abstract: A printing unit having a press unit is disclosed. Damping solution is applied to a form cylinder by way of direct damping-solution supply via a damping unit in such a way that a damping-solution applicator roll which is set away from an ink distributor roll and is driven by way of friction by the form cylinder rolls only on the form cylinder and thus applies the damping solution to the form cylinder only directly via the damping-solution applicator roll. In the event of indirect damping-solution supply in which the damping-solution applicator roll rolls exclusively on the ink distributor roll and is driven by way of friction by the ink distributor roll, in order to switch over to direct damping-solution supply, the damping-solution applicator roll is set away from the ink distributor roll more quickly than the damping unit, and thus the damping-solution applicator roll, is set against the form cylinder.Type: ApplicationFiled: September 18, 2009Publication date: March 25, 2010Applicant: MAN Roland Druckmaschinen AGInventors: Anton Stadlmair, Helmut Stuhlmiller

Publication number: 20060230954Abstract: A printing unit of a web-fed rotary press has a plurality of press units, each press unit having a forme cylinder, a transfer cylinder, an inking unit and optionally a damping unit, and having at least one impression cylinder. Each forme cylinder rolls on the respective transfer cylinder and each transfer cylinder rolling on an impression cylinder in a thrown-on position of the printing unit, in order to apply single-color printed images onto a printing material which is moved through between the transfer cylinders and the or each impression cylinder. Each forme cylinder bears a plurality of printing images next to one another in the axial direction, by which corresponding single-color printed images are applied to the printing material.Type: ApplicationFiled: April 13, 2006Publication date: October 19, 2006Applicant: MAN Roland Druckmaschinen AGInventors: Stefan Albrecht, Rainer Burger, Norbert Dylla, Helmut Stuhlmiller

Publication number: 20060207453Abstract: A rubber sleeve for a printing press, having an at least two-layer structure, is disclosed. The rubber sleeve has an inner layer formed as a carrier layer and an outer layer formed as a functional layer and used for the printing process, the carrier layer and the functional layer being a constituent part of a rubber blanket, which is shaped in the manner of a sleeve in order to form the rubber sleeve and is connected to itself in the region of mutually opposite joint faces of the carrier layer and the functional layer. At least the joint faces of the carrier layer being enlarged in such a way that the same absorb circumferential forces acting on the rubber sleeve.Type: ApplicationFiled: March 20, 2006Publication date: September 21, 2006Applicant: MAN Roland Druckmaschinen AGInventors: Alfons Grieser, Eduard Hoffmann, Georg Schmid, Helmut Stuhlmiller

Patent number: 6640705Abstract: The most uniform possible temperature variation along the circumference of a transfer cylinder in a rotary printing machine is achieved by arranging a highly thermally layer made of a material having a thermal conductivity significantly higher than steel under a rubber blanket on the transfer cylinder for distributing heat from the rubber blanket along the direction of the surface of the transfer cylinder. The highly conductive layer is arranged on a support of the rubber blanket.Type: GrantFiled: May 10, 2000Date of Patent: November 4, 2003Assignee: MAN Roland Druckmaschinen AGInventors: Helmut Stuhlmiller, Reinhard Zeller, Eduard Hoffman

Patent number: 6622626Abstract: A rotary offset printing machine having printing units each with a dampening unit and an inking unit with a metering device for setting an inking profile zone can reach the continuous printing state quickly and with little accumulation of rejects. First an inking profile is set on the metering device that is the inverse of the inking profile for continuous printing with the applicator rolls set off the printing plate and the machine operating at a first rotational speed. A defined quantity of ink is supplied to the inking unit, the inking profile for continuous printing then being set on the metering device. The rubber blankets are pre-dampened and, when a third rotational speed is reached, the print is set on. Finally, the printing machine is run up to a fourth speed for continuous printing when the separation of rejects is concluded.Type: GrantFiled: February 15, 2002Date of Patent: September 23, 2003Assignee: Man Roland Druckmaschinen AGInventors: Helmut Stuhlmiller, Reinhard Zeller

Patent number: 5488903Abstract: For the register of a sleeve-shaped offset priming form in which the beginning and end of the plate-shaped blank of the printing form are connected by a weld seam, a guide element in the form of a projection is provided for the sleeve at the inside of the sleeve. A form cylinder which can be used in combination with the sleeve has a groove extending along its entire width, which groove has a depth that is greater than the height of the projection. The projection can be inserted completely into the groove so that the sleeve can be secured on the form cylinder in the circumferential direction.Type: GrantFiled: May 13, 1994Date of Patent: February 6, 1996Assignee: MAN Roland Druckmaschinen AGInventors: Ingo Kobler, Anton Stadlmair, Helmut Stuhlmiller, Alfons Grieser
