The voltage difference between the tachogenerators 3 and 4 of the coiler and the last stand, which is a function of static current, is fed to the input of function converter 5. The function converter changes the setting of the static current setting by acting on unit 6 to limit intermediate operational amplifier I depending on the difference the angular velocities of the cage and winding device, and hence the radius of the roll. To set up the functional converter 5, a calculated dependency is necessary. As the coil radius increases, the tension increases and the speed of the winding motor decreases. The decrease in speed is controlled by the tachogenerator 3 and the amperage device, the signal of which is fed to the input of the functional converter 5. The functional converter through the block 6 limiting intermediate operational amplifiers "1" changes the reference to a static current, thereby maintaining the tension constant or changing it according to the specified to the law. The proposed device, in comparison with the known one, has a simpler circuit, controls the static current of the motor of the winding device, which provides more accurate maintenance of tension in the steady state, and also allows to form various laws of tension variation with an increase in the roll radius. Apparatus of the Invention A device for changing the tension of a strip by a winding device, comprising an intermediate operational amplifier, a tachogenerator of a winding device and a functional transducer, the input of which is connected to the tachogenerator of the last stand, characterized in that a static generator is added to it to control the tension current and limiting intermediate operational amplifier, connected to the output of the functional converter, the input of which is connected to the tachogener winding device, which is connected to the tachogenerator of the last stand, and the static current setting device is connected to the input of the intermediate op amp.
