Method and device for ascertaining the lateral strip contour or the position of the strip edges of a running metal strip

Abstract

A device for ascertaining the lateral strip contour and/or the position of the strip edges of a metal strip. It includes at least one sensing element for ascertaining suitable measurement data. The sensing element is integrated into a lateral guide (17) together with a main part module of the metal strip conveying device. The lateral guide (17) includes at least one wear element (15a, 15b, 15c) which is arranged in the lateral guide and which comprises a wear element adjusting device that can be rotated about a rotational axis (20) substantially perpendicular to a guide plane of the lateral guide (17). The wear element (15a, 15b, 15c) together with the wear element adjusting device is designed as a sensing element. In an operating method, at least one sensing element (15a, 15b, 15c) is brought into contact with a lateral edge at a starting time, and suitable measurement data is ascertained using the sensing element while the metal strip runs past the sensing element. The strip course can be corrected on the basis of the ascertained measurement data using corrective measures on one or more roll stands and/or on one or more lateral guides (17) of the rolling mill.
