Title
(EN) Device and method for measuring and setting the web tension between inking stations of a multicolor press
Abstract
(EN)

A device for measuring and setting the web tension on a printing press with several inking units (Dn) has measuring means (Mm,n) for measuring the web tension and setting means (Fn) for setting the web tension, using which the web tension can be set actively in the case of unsteady web tension conditions.

The measuring means (Mm,n) and the setting means (Fn) are disposed in such a manner that the web tension can be measured and set between the print areas of two inking units. A control device is provided, which controls the setting means based on the measured values of the measuring means (Mm,n).
