A roll for use in determining the shape of metal strip.

摘要

To determine the shape of metal strip moving in the direction of its length, a roller is urged against the underside of the strip and the tension across the width of the strip is a measure of the shape of the strip. To measure the tension, the roll consists of an annular ring (3) fitted around a rotatable arbor (1) but separated therefrom by an elastic body (5) which permits displacement of the ring in the direction towards and away from the arbor. The displacement of the ring relative to the arbor is detected (7) and employed to indicate the tension in the strip.
