Patent number: 7988608Abstract: An apparatus for producing longitudinally folded products has a machine frame (17) which is arranged below a former arrangement which can be charged with web material. Transporting and processing units are arranged in tandem in the machine frame (17), and a superstructure wall (18) which carries web guiding members (19) associated with the former arrangement is mounted on the machine frame (17). At least one web ribbon (2a) is guided through the superstructure wall (18). The machine frame (17) has at least two modules (22, 23) arranged one above the other which are rotatable by 180° relative to one another and can be connected to one another. Each module (22, 23) has its own at least one drive motor, and every unit provided in the region of the dividing line (24) between modules (22, 23) which are rotatable relative to one another is constructed symmetrically with respect to a center working plane containing the axis of rotation.Type: GrantFiled: May 21, 2009Date of Patent: August 2, 2011Assignee: manroland AGInventors: Helmut Schnell, Urban Spatz

Patent number: 7980541Abstract: A device for distributing successive products of a product flow, particularly the successive folding products produced by a cross cutting device by dividing a material web, to two branch flows, with a wedge arrangement which is arranged in a stationary manner in the transporting plane of the product flow and which engages between two cam rollers which flank it and which are arranged symmetrically with respect to the center working plane. The device is characterized in that the wedge arrangement engages between two guide plates which flank it and which, together with the wedge arrangement, define a path fork. The guide plates have slots through which they are alternately penetrated by cams of the respective adjacent cam roller which are associated with the slots, so that the penetrating cams and the guide plate which is not penetrated form a feed for a belt guide associated with a branch flow.Type: GrantFiled: May 27, 2009Date of Patent: July 19, 2011Assignee: manroland AGInventors: Helmut Schnell, Urban Spatz

Publication number: 20050269379Abstract: The invention relates to an apparatus for threading webs into rotary presses that enables automatic paper threading. The apparatus includes a flexible threading element for guiding the web through a folder of the rotary press. The flexible threading element is guided in a threading guide and is movable by a drive. The threading element following the web is inclined with respect to a longitudinal axis of the web and rotated about the longitudinal axis.Type: ApplicationFiled: May 5, 2005Publication date: December 8, 2005Applicant: MAN Roland Druckmaschinen AGInventors: Helmut Schnell, Christian Winterholler

Patent number: 6740023Abstract: The folder superstructure is provided with a copy diverter for dividing up a product stream of individual copies. The copy diverter includes at least one rotating disc deflector and a tongue, arranged at a location where the product stream branches into two sub-streams. It is assigned at least one first belt conveying apparatus, which is arranged upstream of the tongue, as seen in the direction of the product stream, and at least one second belt conveying apparatus which is arranged in the region of the tongue. The rotating disc deflector has a plurality of disk segments arranged axially one behind the other on a spindle running transversely to the product stream. In order to set different deflecting positions, the disk segments can be fixed in different circumferential positions.Type: GrantFiled: September 28, 2001Date of Patent: May 25, 2004Assignee: MAN Roland Druckmaschinen AGInventor: Helmut Schnell
