The invention relates to a method and a device for arranging sheets in an overlapping position in a transfer unit arranged between a first processing station and a second processing station following the first processing station in a transport direction of the sheets. The sheets to be overlapped are transported from the first processing station to the transfer unit, in a transport plane and each individually lying behind one another. A respective rear, in the transport direction, edge of the sheets coming from the first processing station, is raised relative to the transport plane exclusively by the use of blown air, and a second subsequent sheet is slid under the rear edge of the respective preceding first sheet.

A method and machine arrangement for sequential processing of sheet-like substrates are disclosed. At least one of a front side and a rear side of the substrates is processed in a production line one after another. A printing ink or another type of ink is applied in at least one non-impact printing device on the respective side of the substrates. The printing ink or the other type of ink is dried. A dispersion coating or a coating cured by UV radiation is then applied onto the respective side of the substrates. The dispersion coating or the coating cured by UV radiation is dried and the substrates are fed to a mechanical processing device for carrying out a further mechanical processing of the substrates. The further mechanical processing is performed by at least one of punching, inserting grooves, separating parts and by breaking out panels from their respective composite in the respective substrate.

A corrugated fiberboard printing device includes a protection device which regulates approaching of a corrugated fiberboard within a predetermined distance against an inkjet head, and a controller. The protection device includes multiple regulation devices which are juxtaposed in a width direction of the corrugated fiberboard, and a movement mechanism which moves each of the multiple regulation devices in the width direction. The controller includes a specific column setting unit which is set to classify a specific column, in which a printing quality is less influenced even when the specific column is regulated by the regulation device, with respect to the corrugated fiberboard in a sheet width direction based on order information, and a movement mechanism control unit which controls the operation of the movement mechanism and moves each of the regulation devices so as to regulate the corrugated fiberboard in the specific column.

A method of forming a digital embossing (17) on a surface (2) by bonding hard press particles (67) to a carrier (68). A liquid binder pattern (P) is applied on the carrier by a digital drop application head. Hard press particles (67) are applied on the carrier (68) and the binder pattern such that some hard press particles are bonded to the carrier (68) by the liquid pattern and non-bonded press particles (67) are removed. The carrier (68) with the bonded hard press particles (67) is pressed to the surface (2) and an embossing is formed when the carrier (68) with the hard press particles (67) is removed.

A light irradiation module includes: a stage on which a substrate and a coating layer on the substrate are seated, and which is configured to move in a first direction; a body on the stage; a light-emitting element in a center of the body, and configured to emit light onto the stage; a first suction tube adjacent to the light-emitting element in a second direction crossing the first direction; a duct connected to the first suction tube; and a suction pump connected to the duct, and configured to supply a negative pressure having an absolute value proportional to an intensity of the light to the first suction tube.

A drying system and method of operating the drying system to dry a printed shrinkable web are disclosed. A web transport is adapted to convey the printed web between a heating apparatus and a cooling apparatus. The heating apparatus directs heat toward the web and the cooling apparatus concurrently chills the web. A temperature sensing device is adapted to develop an indication of a temperature of the web and the controller is adapted to adjust a temperature of at least one of the heating apparatus and the cooling apparatus in accordance with such indication.

A printing press arrangement has a plurality of processing stations for processing sheets. The plurality of processing stations are arranged one after another in a transport direction of the sheets for in-line processing of the sheets. At least one of the processing stations is configured as a non-impact printing device. A transfer device, which is arranged upstream of the active region of the non-impact printing device, is provided for transferring the sheets from a first processing station, which is arranged upstream of the non-impact printing device, to the non-impact printing device. The transfer device aligns, in each case, at least one of the axial register and the circumferential register and the diagonal register of each of the sheets in register relative to the printing position of the non-impact printing device.
