Method for the on-line nondestructive measurement of a characteristic of a continuously produced

Image Number 4 for United States Patent #5373545.

The process measures a characteristic (X) which is difficult to measure of a continuously produced product and comprises:choosing at least one easily measurable second characteristic (Y) whose variations are correlated to the variations of the first characteristic;modifying, by means acting on the product in a given zone of the production line, the first characteristic so as to put it into a known predetermined reference state (X.sub.o);taking at least in said zone a measurement of the second characteristic, and;processing said measurement for determining a variation in the first characteristic relative to the reference state (X).Application in the measurement of the flatness of a strip continuously travelling through a levelling machine.FIG. 2.
