Abstract: An apparatus positions sheets preferably moving in a combination folding machine and defines a trailing edge range. A trailing edge of the sheet is to be positioned in a transport direction, depending on the dimensions of the sheet. The apparatus has positioning devices, by which the trailing edge can be positioned. The positioning devices are fixed to a carrier, and also a carrier actuating device is provided, by which the carrier can be moved by a predefined actuating travel in the transport direction of the sheets, so that the trailing edge is positioned within a trailing edge positioning range. The positioning devices are fixed to the carrier such that the respectively different trailing edge positioning ranges of the individual positioning devices in total cover the entire trailing edge range but each respective trailing edge positioning range is shorter in the transport direction than the trailing edge range.

Abstract: An apparatus for processing preliminary products in the graphics industry with the preliminary products at a standstill in a processing position, includes a conveyor by which the preliminary products can be transported in a transporting direction, along a transporting section, into the processing position, a drive that operates the conveyor, a detector that detects a respective preliminary product en route along the transporting section, and a controller that is linked up with the detector and the drive and by which the drive can be brought to a temporary standstill when the respective preliminary product reaches the processing position. On account of stops not being present, the preliminary products remain intact at least along their leading edges, as seen in the transporting direction, there are no marks on these edges, and the set-up times during a changeover of the format of the preliminary products are relatively short.

Abstract: A device for adjusting a folding blade has a push rod assembly with which the folding blade is coupled for producing a vertical movement of the folding blade. The push rod assembly has an inner push rod, an outer push rod and a positioning device for adjusting a position of the outer push rod relative to the inner push rod. The positioning device is firmly secured to a frame relative to at least one of the push rods. A folder includes at least one folding unit with a folding blade and the device for adjusting the folding blade.
