In some examples, a processing machine for processing a substrate includes at least one shaping unit and/or at least one application unit. The at least one application unit and/or the at least one shaping unit in each case includes at least one forme cylinder and at least one impression cylinder. The at least one forme cylinder of the application unit includes at least one application forme including at least one application surface and/or the at least one shaping unit includes at least one shaping tool including at least one working surface.

The invention relates to a method of aligning a plurality of printed motifs on a sheet (3) in a converting machine (10). An actual position (Pa_1) at a first sensor is defined as an initial reference position (P_ref1) for the sheet, and at least one displacement error (?d2) is calculated and compared to a first threshold (T1). If the displacement error is lower than the first threshold, then the angular position (?) of a printing cylinder (42) in the second flexographic printing unit (16b) is adjusted. However, if the error is higher than the first threshold, then at least part of the of the displacement error (?d_2) is corrected by modifying the speed (V) of a vacuum transfer unit located between the first printing unit and the second printing unit.

A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in sucession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.

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.

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.

In some examples, a processing machine for processing a substrate includes at least one shaping unit. The at least one shaping unit includes at least one forme cylinder and at least one impression cylinder. A processing point for processing a substrate is arranged between the at least one forme cylinder and the at least one impression cylinder. The processing machine includes a control unit for correcting a processing length of the substrate, and which controls a speed of at least one of the at least one forme cylinder or the at least one impression cylinder. The at least one forme cylinder and the at least one impression cylinder have a speed ratio with respect to one another that is changeable at the processing point as a function of the processing length of the substrate, and the speed ratio differs at least once within a full cylinder revolution.

A printing machine for printing on a printing substrate web includes a plurality of inline flexographic printing units which are disposed in a plane accessible to an operator of the machine. Each one of the two flexographic printing units of a respective duplex printing station includes a respective impression cylinder and a dryer disposed between the two impression cylinders along a path of web travel of the web of printing substrate. A method of operating the printing machine is also provided.

A system for manufacturing bags with counting marks includes a workstation for making bags, and a coding machine for spraying counting marks on the bags. The coding machine includes a main body, a fixing structure and a spraying gun. The main body has ink cartridges for providing ink and a pressure mechanism to spray the ink through the spraying gun. The spraying gun is fixed to a fixing structure and connected to the main body via a cable such that the ink of the ink cartridges is operably moved from the ink cartridge to the spraying gun via the cable. The cable includes channels, each channel adapted for delivering a respective color of the ink. The spraying gun includes nozzles coupled to the channels for spraying the ink on the bags so as to form the counting marks thereon.
