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.
