Zusammenfassung:	There is described a web alignment device (21) for aligning a web (5, 4) comprising an engagement surface (22) for supporting the web (5, 4), a clamp assembly (23) for clamping the web (5, 4) on at least a clamp portion of the engagement surface (22), an alignment control assembly (24) for controlling a correct alignment of the web (5, 4). The alignment control assembly (24) comprises a control unit (43) for generating a trigger signal if the web (5, 4) is correctly aligned, a first sensor device (44) for detecting and/or determining a desired position of a first section (45) of the web (5, 4) and to send at least a first signal to the control unit (43) if the first section (45) is positioned in the desired position, and a second sensor device (46) for detecting and/or determining a desired position of a second section (47) of the web (5, 4) and to send a second signal to the control unit (43) if the second section (47) is positioned in the desired position.
