Patent number: 6733431Abstract: Multi-section print material, such as a newspaper, is folded so as to enable inserts to placed at any location or at multiple locations within the half fold. Several sections are stacked onto one another with one of the signatures offset in the transport direction by a given amount. When the stack is subsequently half-folded, the protruding signature forms a lap which enables an insertion device to automatically insert at the lap position. The system may be operated in straight operation or collect operation. In one embodiment, the sections are transported in two web paths where they are cut into signatures. One of the web paths is delayed so that its signature arrives at the half fold gripper or pin cylinder slightly later than the signature from the other web path. The subsequently formed half fold has the trailing edge of the later-arriving signature protruding by a given lap amount that enables the downline inserter to insert at that position.Type: GrantFiled: September 19, 2001Date of Patent: May 11, 2004Assignee: Heidelberger Druckmaschinen AGInventor: Charles Henry Dufour

Patent number: 6684775Abstract: A printing unit includes a plate cylinder, a blanket cylinder for printing a first side of a web of material, and an inker for inking the plate cylinder, the inker being movable between an active position and an inactive position, the inker contacting the plate cylinder in the active position and the inker being separated from the plate cylinder in the inactive position. A plate operation unit such as a direct imaging device or a plate exchanger is movable into the active position of the inker when the inker is in the inactive position.Type: GrantFiled: June 7, 2001Date of Patent: February 3, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Charles Henry Dufour, Charles Reif Hammond, John Thomas Lorrey

Patent number: 6615731Abstract: A printing press comprising a multi-plate plate cylinder for carrying at least a first printing plate and a second printing plate, the plate cylinder having a cylinder body with an outer surface and a lock-up bar having a retracted position and an extended position, the lock-up bar for fastening both of the first and second plates about the outer surface in the retracted position. A tucker bar is located adjacent the lock-up bar, the tucker bar including at least a first segment for tucking and holding the first printing plate on the plate cylinder and a second segment for tucking and holding the second printing plate on the plate cylinder, the first segment being independently movable with respect to the second segment.Type: GrantFiled: June 10, 2002Date of Patent: September 9, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Mark Bernard Dumais, Charles Henry Dufour, Lev Zlatin, Glenn Alan Guaraldi

Patent number: 6553908Abstract: A printing cylinder has a first rotatable section having a central image area on the surface, and a first and second end. A first shell is disposed circumferentially about the first end, and a second shell is disposed circumferentially about the second end, the first and second shells having image areas on the surface and movable axially with respect to the central image area. Also provided is a printing press comprising a first sensor for detecting register marks, a second sensor for detecting fanout, and a rotatable cylinder with a first section axially adjustable with respect to a second section. A method for correcting fanout in a web printing press includes sensing register marks to provide overall circumferential and/or lateral register adjustments of a printing cylinder, sensing a section of the web other than the register marks to provide fanout information, and changing a lateral position of a first part of the printing cylinder with respect to a second part of the printing cylinder.Type: GrantFiled: September 29, 2000Date of Patent: April 29, 2003Assignee: Heidelberger Druckmaschinen AGInventors: John Sheridan Richards, Charles Henry Dufour
