Tension measurement and control in cold-strip mills

THE COLD rolling of steel strip on tandem mills requires the measurement and control of tension in the strip, and to meet this requirement the tensiometer herein described has been developed. The tensiometer produces a continuous indication of the tension in the strip during the rolling operation, and functions in connection with auxiliary control equipment to automatically maintain the tension at any desired value. An additional function of the tensiometer is the instantaneous indication of any difference in tension between the 2 edges of the strip.
