Sheet-fed printing press
10882307 · 2021-01-05 · ·

The invention relates to a sheet-fed printing press having a feeder, a delivery, and at least one sheet guiding cylinder, which is arranged between the feeder and the delivery, has a gripper system, and is assigned a digital printing system and a first sheet guiding system that removes sheets from the sheet guiding cylinder. The object of the invention is to devise a sheet-fed printing press that can be used in a more variable fashion, and with which a particularly wide spectrum of different products can be produced. According to the invention, the object is attained in that the first sheet guiding system (12) is configured for selectively transferring the sheets to a second sheet guiding system (8), which transfers the sheets to the sheet guiding cylinder (3), or for transferring said sheets to the delivery (11), wherein the second sheet guiding system (8) is configured as a perfecting system (8) and can be switched between an operating mode in which it feeds the sheets in a reversed position to the sheet guiding cylinder (3) and an operating mode in which it feeds the sheets in a non-reversed position to the sheet guiding cylinder.

Method and application device for applying a transfer layer of a film to a substrate

A method for applying a transfer ply of a foil to a substrate, with the steps of: a) regionally applying a radically curable adhesive to the transfer ply and/or the substrate by means of an inkjet printhead; b) precuring the adhesive by UV irradiation; c) applying the transfer ply to the substrate by means of a stamping apparatus; d) fully curing the adhesive by UV irradiation; e) peeling a carrier ply of the foil, to leave at least one first subregion of the transfer ply on an application region of the substrate, and at least one second subregion of the transfer ply on the carrier ply; f) winding up or recoiling the carrier ply with the remaining second subregion of the transfer ply; g) applying at least one further subregion of the transfer ply remaining on the carrier ply to the substrate by at least once repeating steps a) to f).

Machine arrangement and method for sequential processing of sheet-type substrates

A machine arrangement, that sequentially processes sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. Further processing stations are a primer application device that primes the substrates and a dryer for drying the primer applied to the substrates. The primer application device and the dryer precede the non-impact printing device, in the direction of travel of 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.

Method for operating a device for printing hollow bodies
10773514 · 2020-09-15 · ·

A method for operating a device for printing hollow cylinder is provided. The device comprises a rotating segmented wheel with a plurality of printing cylinders arranged successively along the periphery of the device. A plurality of plate cylinders are provided in association with the segmented wheel. According to a printing process to be performed, a selected quantity of plate cylinders is thrown onto the segment wheel or is thrown off the segment wheel. In a first printing process, a first partial quantity of thrown-on plate cylinders transfers printing ink to a plurality of the printing blankets arranged on the segment wheel. At the end of the printing process, at least some of the plate cylinders, that were thrown on the segment wheel in the first printing process, are thrown off the rotating segment wheel. During constant uninterrupted rotation of the segment wheel, for the implementation of a second printing process, a second partial quantity of plate cylinders is thrown onto the segment wheel and respectively transfer printing ink to a plurality of the printing blankets arranged on the segment wheel. The respective printing forme of at least one plate cylinder involved in the first printing process, and uninvolved in the ongoing second printing process, is changed during the ongoing printing process.
