A method for generating decks of sheet elements (18) comprises the steps of positioning a set of numerous sheet elements (18) onto a transport surface of a transport device (30) to partly overlap in transport direction (T). The set of overlapping sheet elements (18) is moved against a stop member (44). The stop member (44) is moved in the transport direction (T) with a lower velocity than a velocity of the transport surface. By maintaining displacement of sheet elements (18) which are not yet contacting stop member (44) all sheet elements are shifted towards stop member (44) to define a deck. The method is carried out by a corresponding device.

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 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.

A machine for folding sheets receives a stream of sheets. A first folding unit is followed by a further unit. The first folding unit has at least one buckle plate and at least two folding rollers to fold the sheets. A monitoring device checks the stream for defects. A control unit activates a removal device for removing waste products when a defect is detected. The monitoring device is disposed at the entry region of the buckle plate and monitors the stream in the buckle plate. The removal device is disposed downstream of the first folding unit and upstream of the further unit. The system, which is suitable for industrial folding machines, reliably detects unusable waste products in the folding process even before production might be affected.

An apparatus, in particular roll-type cross cutter, is shown and described, further in particular for forming a shingled stream of underlapping or overlapping sheets, in particular sheets of paper or cardboard, having a cross-cutting device for cutting a material web into individual sheets and having a web storage upstream of the cross-cutting device along the web transport path for storing and/or providing a material web, the material web being fed to the web storage from a web unwinding. According to the invention, it is provided that the web storage for storing the material web is arranged in the region of the cross-cutting device below the running height of the sheets.
