the torque control block 48 a rotational speed limit tapped from the second driving unit 20 is transmitted to the input of the torque control block 48 in order to act there on the input value into the torque control block 48 the output of the torque control block 48 is connected with the second driving unit 20 the main driving unit 13 is connected with the low pass filter block 34 via signal line 30 and is connected with the high pass filter block 46 via signal line 31 thus depending on the control pattern the filtering characteristics of the low pass filter block 34 or the high pass filter block 46 can be adjusted depending on the process speed or printing speed of the main driving unit 13 it should be noted that the connection of the main driving unit 13 with the high pass and low pass filter blocks 34 46 of the first and second control devices 24 25 is not absolutely necessary with reference to fig3 the basic design of the control method is described hereinafter in greater detail with the tension control device 16 in operative position in this method the tension of the substrate web 7 is basically measured with the aid of a measuring unit 22 and its measured value is processed further in different filtering devices and used for controlling the first and second driving units to put it more precisely the tension of the substrate web 7 is measured with the aid of the measuring unit 22 in step 60 the output signal resulting therefrom or the measured value of the measuring unit.
