Machine arrangement with printing unit for the sequential processing of sheet-type substrates
A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.

Device, method and printing press for multiple printing of printing substrate sheets
The invention relates to a device for printing sheets of printing substrate (02), having a first printing nip (12) which is formed between a first cylinder (19; 19*) that acts as a transport cylinder (19; 19*) and a second cylinder (18), and in which the printing substrate sheets (02) can be printed on one or on both sides with one or more collected print image segments, and having a second printing nip (11) lying downstream in the printing substrate path, which printing nip is disposed at a level lying below the first printing nip (12) and is formed between a third cylinder (17) that acts as a transport cylinder (17) and a fourth cylinder (16), and in which the printing substrate sheets (02) can be printed on one or on both sides with one or more collected print image segments, wherein the printing substrate sheets (02) can be conveyed via at least one rotating transport means (33; 38; 39) along a transport path from the cylinder (19; 19*) that acts as a transport cylinder (19; 19*) of the first printing nip (12) to the cylinder (17) that acts as a transport cylinder (17) of the second printing nip (11), wherein on the transport path, downstream of the cylinder (19; 19*) that acts as a transport cylinder (19; 19*) of the first printing nip (12) and upstream of the cylinder (17) that acts as a transport cylinder (17) of the second printing nip (11), at least one first electrode (37; 41) directed toward the outer circumference of the at least one rotating transport means (33) is arranged in an angular segment lying in the transport path for the printing substrate sheets (02) in such a way that when an electric voltage is applied, a printing substrate sheet (02) being guided past the electrode (37; 41) can be electrostatically charged.
Machine arrangement for sequential processing of sheet-type substrates
A machine arrangement, for sequentially processing sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. The processing station, including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged. On the circumferential surface of the printing cylinder, four substrates are or can be placed behind each other in the circumferential direction. Each of the substrates that are to be conveyed are retained in one of a force-locking and a form-fitting manner on the circumferential surface of the printing cylinder by at least one retaining element.

OPTICAL MEDIA SENSOR WITH BLOWER
An optical media sensor includes a guide wall, a light emitter, a light receiver and a blower. The guide wall has an opening. The light emitter emits light to a medium sheet through the opening. The light receiver detects an amount of light travelling from the medium sheet. The blower generates a wind pressure that presses the medium sheet against the guide wall when detecting the amount of light.

FOLDING APPARATUS OF AN OFFSET WEB-FED PRINTING PRESS AND OFFSET WEB-FED PRINTING PRESS
A folding apparatus of an offset web-fed printing press includes a first transport means formed as belt conveyor system for a web-shaped printing material and configured such that belts thereof can be driven at a speed, which corresponds to the speed of the printing material, and a first cutting means arranged in the region of the first transport means configured such that it severs the printing material in a format-variable manner in those sections not covered by the belts of the first transport means, and a second transport means arranged downstream from the first transport means and formed as belt conveyor system, the belts of which are offset relative to the belts of the first transport means transversely to the transport direction of the printing material, configured such that the belts thereof can be driven at a speed larger than the speed of the belts of the first transport means.
