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.

Abstract: 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.

Abstract: A method of operating a printing press, wherein lubricated components of the printing press are lubricated with lubricant during the operation of the printing press in such a way that lubricant is taken from a reservoir via a feed line and is supplied to the component or components to be lubricated and in that the lubricant is carried away from the respective component to be lubricated in a post-feed area. Metal particles in the lubricant in the area downstream of the respective component to be lubricated are detected by means of a sensor. The state of the respective component to be lubricated is determined on the basis of this measurement and, if need be, a repair or exchange of the respective component to be lubricated is initiated.

Abstract: Exposed printing plates are bent in the area of a bending device to form a leading end and a trailing end. Each exposed and bent printing plate is grasped in the area of the bending device at the leading end or at the trailing end of the printing plate by means of a gripping bar and transferred together with the gripping bar to a transporting device. The transporting device transports the printing plate together with the gripping bar toward a printing press, where the printing plate is removed together with the gripping bar from the transporting device in the area of the printing press. While grasped by the gripping bar, the plate is transferred to a form cylinder of a printing mechanism of the printing press.

Abstract: A method of printing an electronic circuit or components thereof uses a printing machine to print a conductive structure on the front printing side (back side of the sheet) of a printing substrate.

Alternatively, the circuit or components of a circuit may be printed by having a printing machine for color printing preceded by a printing machine for printing on the back side of the printing substrate. A chip is applied to the printing substrate where the back side of the printing sheet with the printing motif is cooled to prevent any negative effect on the printing motif and/or the printing substrate.

Abstract: A method for evaluating an image of a predetermined extract of a printed product makes corrections to a white reference to account for spatial variations and changes of illumination intensity over time. Intensity signals recorded from first predetermined areas within the extract are combined arithmetically with reference data values that represent a measure of the intensity of the light reflection from unprinted regions of the printed product. At the start, an image of a white reference is recorded and basic reference data for the entire extract are derived from the intensity signals of this image. During each evaluation of an image of the predetermined extract, correction data are derived from intensity signals recorded from second predetermined areas within the extract.
