<p>The disclosure of the present invention relates to a method and apparatus for controlling tension in a moving strip passing between two rolling mill stands. A piston cylinder assembly to which a strip-engaging roller is attached is employed to urge the strip away from a straight path of travel. On one side of the cylinder assembly roller a second roller is arranged to contact the strip and with which there is associated a load measuring device for measuring the tension in the passing strip. A signal representing the measured tension in the strip is compared with a signal representing a desired tension by a control that varies the operation of the piston cylinder assembly to reduce any difference between the two signals to a desired value, for example, a zero value.</p> |
