Abstract

Es ist ein Falzapparat (2) und ein Verfahren für die Bearbeitung eines von einer Druckmaschine kommenden Stromes von bedruckten Signaturen 7, 8, 9) vorgesehen, womit Papierstaus verhindert werden. Die Signaturen bewegen sich auf einem gewünschten Pfad mit Pfadkanten (70A, 70B) und jede Signatur weist eine Vorderkante (7A, 8A, 9A) und eine Hinterkante (7B, 8B, 9B) auf. Der Falzapparat (2) umfaßt eine Vielzahl von Sätzen von Sensoren (50, 53; 52, 54), welche jeweils ermitteln, ob die Vorderkante und/oder die Hinterkante der Signatur von der Pfadkante um mehr als einen gewissen Toleranzwert abweicht.

Figure 00000001
A folder (2) and a method for processing a stream of printed signatures 7, 8, 9 coming from a printing press are provided, thereby preventing paper jams. The signatures move on a desired path with path edges (70A, 70B) and each signature has a leading edge (7A, 8A, 9A) and a trailing edge (7B, 8B, 9B). The folder (2) comprises a plurality of sets of sensors (50, 53; 52, 54) which each determine whether the leading edge and / or the trailing edge of the signature deviate from the path edge by more than a certain tolerance value.
