摘要： A control device comprising a first driving unit (18) with a first driving roller (19) around which a substrate web (7) is partially guided and tensioned, and comprising a second driving unit (20) with a second driving roller (21) around which the substrate web is partially guided and tensioned, has been suggested in order to provide a control device (16) for controlling the tension of the substrate web that is conveyed along a transport path, said control device making it possible to avoid the problems of prior art. The first and the second driving units of this control device feature different rotational moments of inertia. Further provided are a measuring unit (22) for providing a measured value of the tension of the substrate web and a control unit in connection with said measuring unit and said first and second driving units, said control unit comprising a first and a second filtering unit displaying different filtering characteristics for filtering the measured value. The control unit comprises a first control device for controlling the first driving unit based on the measured value filtered by the first filtering unit, as well as a second control device for controlling the second driving unit based on the measured value filtered by the second filtering unit. Thus, the driving units are enabled in a manner that has been advantageously adapted to the dynamic behavior that is affected by the rotational moments of inertia of said driving units. Also disclosed is a method for controlling the tension of a substrate web, said method comprising the steps of measuring the tension of the substrate web and of generating a measured value as a function of said tension. Then the measured value is filtered parallely in a first and in a second filtering unit displaying different filtering characteristics and the first driving unit is controlled depending on the measured value filtered by the first filtering unit, and the second driving unit is controlled depending on the measured value filtered by the second filtering unit. In this method, the measured value is used, at the same time, as the control value for two different driving units and is, for this purpose, processed with respect to the dynamic characteristics of the driving units.
