Abstract

Die Erfindung betrifft eine Vorrichtung zur Ermittlung der Bahnspannung bzw. des Bahnzugs in einer Bedruckstoffbahn (20), wobei an einer ersten Position (24) entlang eines Transportwegs der Bedruckstoffbahn (20) eine Einrichtung (26) angeordnet ist, die ein Signal liefert, welches einen Rückschluss auf die an der ersten Position (24) herrschende Bahnspannung bzw. den an der ersten Position (24) herrschenden Bahnzug ermöglicht. Erfindungsgemäß umfasst die Vorrichtung eine Einrichtung, welche die an einer zweiten Position (25) entlang des Transportwegs der Bedruckstoffbahn (20) herrschende Bahnspannung bzw. den an der zweiten Position (25) herrschenden Bahnzug rechnerisch ermittelt, nämlich aus der an der ersten Position (24) herrschenden Bahnspannung bzw. aus dem an der ersten Position (24) herrschenden Bahnzug sowie aus Kräften, die mindestens eine angetriebene Walzen (22) und/oder mindestens eine geschleppte Walze (21), die entlang des Transportwegs der Bedruckstoffbahn (20) zwischen der ersten Position (24) und der zweiten Position (25) angeordnet ist, in die Bedruckstoffbahn (20) eintragen.

The invention relates to a device for determining the web tension or the web tension in a printing material web (20), wherein at a first position (24) along a transport path of the printing material web (20) a device (26) is provided which provides a signal which a conclusion on the prevailing at the first position (24) web tension or at the first position (24) prevailing web draw allows. According to the invention, the device comprises a device which calculates the web tension prevailing at a second position (25) along the transport path of the printing material web (20) or the web tension prevailing at the second position (25), namely from the first position (24 ), or from the web tension prevailing at the first position (24) and from forces which comprise at least one driven roll (22) and / or at least one towed roll (21) along the transport path of the printing material web (20) between the web first position (24) and the second position (25) is arranged in the substrate web (20) enter.
