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: The invention provides a method for determining parameters relevant to the print quality of a printed product. A macroscopic photogram of a measuring field of the printed product is recorded using a camera having a macro lens. An actual value of a parameter relevant to the print quality is determined from the macroscopic photogram. The actual value is compared to a nominal value of the parameter relevant to the print quality. Whether the measuring field is printed with adequate quality is determined based on the comparison of the actual valve with the nominal value of the parameter relevant to the print quality.

Abstract: The aim of the invention is to improve the supply of transfer foil in a coating module in which the image-forming layers of a transfer foil are transferred to a printing material. To achieve this, a partial pressing surface is located in the coating module for transferring the layers of the transfer foil. This permits targeted control of the foil feed. The transfer foil can be fed past a pressure cylinder in an approximately tangential manner and with a limited width.

Abstract: For transferring an image-forming layer from a transfer foil a printing sheet, an adhesive layer is first applied to the sheet to be printed. The transfer foil provided with the image-forming layer is guided past the printing sheet under pressure, in a coating module (2), such that the image-forming layer adheres to the adhesive and an image is created. The present invention provides a foil transfer device that includes a substrate on the press cylinder that has a reduced adhesiveness relative to the transfer foil.

Abstract: 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.

Abstract: For more efficient and energy-saving drying of ink and/or coating films in printing machines, the drying or hardening process must be better monitored. Therefore a method is proposed for determining the degree of hardening of one or more printed ink and/or coating films on a substrate that was coated in an intaglio, flexographic or offset printing process. The degree of hardening or drying due to the hardening or drying process is determined indirectly via the change of mechanical and/or viscoelastic properties of the ink and/or coating films on the substrate. An ultrasound measurement is used for this purpose.

The longitudinally folded paper web is guided to folding cylinders. The folding cylinders further process the uncut paper web to form cut sheets. The still uncut paper web is actively transported by at least one transporting device.

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.

During each light pulse, the predetermined extract on a printed product moves into the area of observation of the camera, and an image of extract is captured.
