ABSTRACT:
A rolling mill strip tension controlling apparatus may also function as a looper roll and shape meter and is provided with a plurality of generally aligned axially rotatable strip contacting rolls which are supported on rotating arms which in turn are rotated by actuators such as hydraulic cylinders. By monitoring actuator pressure and position a difference between the actual values for position or pressure and the predetermined values is used to provide through a servomechanism suitable corrective action on an individual roll by roll basis. A switch may be provided to permit the system to provide information from a computer to the servo system in a position mode or a pressure mode. The measured values may take the form of oscillations with respect to a predetermined base value.
