The present invention relates to a device for treating substrates which device is modular and versatile in use. The device for treating substrates comprises a feeder and one or more first sub-structure modules which each comprise a pressure cylinder with devices for fixing a lift and a sheet-conveying device and one or more second sub-structure modules which respectively have a transport cylinder with openings formed on the cover surface thereof, and having devices for fixing a lift and a sheet conveying device. All of the first or second sub-structure modules have the same intersection point for connecting the sub-structure modules on one of the inlet and the exit side and they all can be equipped with an attachment module.

A guide member (14) has an upper surface assisting conveyance of workpieces (44) mounted on a table (12) and is arranged downstream of the table (12) in a workpiece conveyance direction. A belt drive mechanism (16) has pulleys (26a to 26d, 28a to 28b), and endless belts (32a to 32d) wound around these pulleys, and is arranged above the table (12) and the guide member (14) so as to stride over the table (12) and the guide member (14). A first opening portion is formed on a bottom portion of the belt drive mechanism (16) to generate an upward suction force. A second opening portion is formed on the upper surface of the guide member (14) to generate a downward suction force. A magnitude of the suction force generated in the first opening portion exceeds a magnitude of the suction force generated in the second opening portion.

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 device for conveying and transferring flexible, flat objects with a gripper conveyor including a plurality of grippers that are movable along a conveying path in a conveying direction, and further with a conveying-way device that forms a conveying rest that, in a transfer region, is arranged below the conveying path such that objects that are released from grippers in the transfer region are deposited onto the conveying rest. The device includes a pressing circulatory device that acts upon the transfer region and has a plurality of outwardly directed pressing arms. The pressing circulatory device is designed, in the transfer region, to press the objects to be transferred with the pressing arms onto the conveying rest such that the objects can be deposited onto the conveying rest in a guided and controlled manner.

A sheet printer includes a sheet conveyor assembly including a first conveyor with a first holding device configured for exerting a holding force on a sheet proportional to a coverage of the sheet on the first conveyor and a second conveyor upstream of the first conveyor including a second holding device configured for holding and releasing the sheet, a print head assembly positioned over the first conveyor, a detector assembly for sensing the transport of the first conveyor, a controller storing on its memory a sheet media catalogue and configured to control a release timing of the second holding device for releasing the sheet partially engaged by the first conveyor based on a media type parameter selected from the media catalogue and to control the print head assembly to commence printing the sheet based on transport information from the detector assembly.

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.
