摘要
Method for measuring a difficult-to-measure characteristic (X) of a continuously manufactured product, characterised in that: - at least one easy-to-measure second characteristic (Y), whose variations are correlated with those of the said first characteristic, is chosen; - the said first characteristic is modified so as to bring it to a known predetermined reference state (X0), via a means acting on the product in a specific zone of the manufacturing line; - the second characteristic is measured, at least in the said zone; and - this measurement is processed in order to determine a variation of the said first characteristic relative to the said reference state (X). Application to the measurement of surface evenness on a strip running continuously through a skin passrolling (temper (pass) rolling) installation. IMAGE
