Publication number: 20150107470Abstract: A printing press with at least one gripperless printing unit of a reel-fed printing press, through which a substrate to be printed can be transported in the horizontal direction by a transport device. A dimensionally stable and relatively stiff piece good, which during the transport and printing does not adapt to cylinder contours of the printing units, can be transported through the or each gripperless printing unit by the transport device. The printing press further includes a feeder, which keeps the piece good to be printed ready and via which the piece good to be printed can be circumference register-precisely and page register-precisely placed on the transport device for the subsequent printing in the printing units.Type: ApplicationFiled: October 16, 2014Publication date: April 23, 2015Applicant: manroland web systems GmbHInventors: Stefan ALBRECHT, Marke Jirous, Xaver Bachmeir, Stephan Fischer, Christian Trometer, Norbert Rothenberger

Publication number: 20090173247Abstract: A printing press cylinder is disclosed. The cylinder includes a lock-up channel extending in an axial direction of the cylinder, where a clamping piece is accommodated in the lock-up channel to clamp a plate on a surface area of the printing press cylinder. The clamping piece includes first feed slants and second feed slants. Projections of the leading edge of a to-be-clamped plate are co-operable with the first feed slants and projections of the trailing edge of a to-be-clamped plate are co-operable with the second feed slants such that the leading edge of the to-be-clamped plate is clampable in a self-centering manner between the clamping piece and a leading channel wall of the lock-up channel and the trailing edge of the to-be-clamped plate is clampable in a self-centering manner between the clamping piece and a trailing channel wall of the lock-up channel.Type: ApplicationFiled: November 14, 2008Publication date: July 9, 2009Applicant: Manroland AGInventors: Xaver BACHMEIR, Eduard Hoffmann, Thomas Kandlbinder, Norbert Dylla

Patent number: 6523469Abstract: A device for metering and equalizing an ink layer on the surface of a printing machine roller, in particular on the surface of an ink applicator roller in the inking unit of a printing machine, the surface being additionally wetted with dampening medium. The device contains at least two doctor blades which are arranged preferably at a short distance one behind the other in the direction of rotation of the roller and rest under pressure against the surface of the roller and of which a front doctor blade, with respect to the direction of rotation of the roller, has a doctor blade edge radius such that essentially only the dampening medium, but not the ink layer, can be wiped off from the surface of the roller by said front doctor blade, while a rear doctor blade, with respect to the direction of rotation of the roller, has, by comparison, a smaller doctor blade edge radius such that at least part of the ink layer which has remained on the surface of the roller can be wiped off.Type: GrantFiled: June 8, 2001Date of Patent: February 25, 2003Assignee: MAN Roland Druckmaschinen AGInventors: Wolfgang Bayer, Andreas Berchtold, Thomas Böck, Robert Konrad, Harald Lesti, Xaver Bachmeir

Patent number: 6389966Abstract: The present invention provides a smoothing roller for a printing unit of a rotary printing machine. The smoothing roller is applied to the form cylinder downstream of the ink applicator roller in relation to the direction of rotation of the form cylinder or onto the ink applicator roller itself. The smoothing roller smooths the ink film on the form cylinder or on the ink applicator roller. The outer surface of the smoothing roller has an ink-repelling characteristic. The ink-repelling characteristic is effected by a liquid ink-repelling material such as a separating agent or a dampening medium that is applied to the outer surface of the smoothing roller or by an outer surface of the smoothing roller comprising an ink-repelling material. The two measures for effecting the ink-repellant characteristic of the smoothing roller may also be provided in combination with one another.Type: GrantFiled: July 28, 1998Date of Patent: May 21, 2002Assignee: Man Roland Druckmaschinen AGInventors: Xaver Bachmeir, Wolfram Fischer, Bernhard Feller

Patent number: 6065402Abstract: An inking device in a printing machine with an ink body filled with printing ink and with a blade. The blade can also be a chamber blade, for example. For temperature moderation, an insulation plate or a heat dissipation plate, by which the temperature of the blade can be adjusted, is arranged on the blade. The heat created by friction between the upper edge of the blade and the surface of the cup roller does not penetrate into the ink duct due to the insulation plate and the heat dissipation plate, so that heating of the printing ink is avoided.Type: GrantFiled: April 27, 1998Date of Patent: May 23, 2000Assignee: MAN Roland Druckmaschinen AGInventors: Bernhard Feller, Wolfram Fischer, Xaver Bachmeir

Patent number: 5960714Abstract: A rotary printing machine in which cylinders are uncovered by a swinging door or a removable flap. Journals are separated from the cylinder bodies and remain, together with bearings arranged in the door or the flap. At a separation point the journals have truncated conical projections which are inserted into corresponding truncated conical depressions in the end face of the cylinder body.Type: GrantFiled: September 14, 1998Date of Patent: October 5, 1999Assignee: Man Roland Druckmaschinen AGInventors: Josef Gottling, Horst Dauer, Xaver Bachmeir, Bernhard Feller

Patent number: 5678486Abstract: A gripper cylinder configurable as a printing cylinder of a sheet-fed printing machine, a feeder drum in a sheet-fed printing machine, or a gripper cylinder in a folder unit. The gripper cylinder includes a stationary stator and a gripper spindle assembly mounted to the cylinder. The gripper spindle assembly includes a gripper pivotably mounted to a gripper support. Instead of using a mechanical cam, the gripper can be controllably pivoted together with a cam roller by an armature that can be magnetized but is not permanently magnetic when an electric current flows through the stator thereby magnetizing a housing of the stator. The armature may be magnetically urged against the restoring force of a spring.Type: GrantFiled: December 10, 1996Date of Patent: October 21, 1997Assignee: MAN Roland Druckmaschinen AGInventors: Xaver Bachmeir, Eckhard Tusche, Johannes Ruschkowski

Patent number: 5644828Abstract: A device for repairing a cylinder in a printing machine while the cylinder is installed in the printing machine. The device includes a cross slide rail having a base body with longitudinal guides, a longitudinal support slidably mounted on the longitudinal guides, and a transverse support connected to the longitudinal support. The cross slide rail is removably mounted to side walls of the printing machine so as to be parallel to a longitudinal axis of the cylinder to be repaired. A pull spindle is rotatably mounted to the base body and operatively connected to the longitudinal support so that the rotation of the pull spindle moves the longitudinal support along the longitudinal guides of the base body. A tool holder is connected to the transverse support for carrying a tool for working the cylinder. A mechanism for driving the cylinder is also provided.Type: GrantFiled: June 17, 1994Date of Patent: July 8, 1997Assignee: MAN Roland Druckmaschinen AGInventors: Colin Sailer, Paul Harmathy, Eckhard Tusche, Thomas Weissbacher, Heinrich Schoder, Xaver Bachmeir, Johannes Ruschkowski

Patent number: 5622111Abstract: A form cylinder (1) for use in a printing machine including at least one cassette (40) and preferably multiple cassettes (40 to 43), each of which is removable from the form cylinder (1) through an opening (37) in a side wall (2). Each of the cassettes contains winding rollers (4) and a printing form extending between the winding rollers. The winding rollers are driven by an externally positioned driving device such as an electric motor (3) to wind and unwind the printing form. The winding rollers are connected to the driving device by a coupling (12) which is movable between an engaged position in which a shaft of each winding roller is connected to a shaft associated with the driving device and an unengaged position in which the winding rollers are not connected to the driving device.Type: GrantFiled: September 15, 1995Date of Patent: April 22, 1997Assignee: MAN Roland Druckmaschinen AGInventors: Xaver Bachmeir, Eckhard Tusch e, Johannes Ruschkowski
