Patent ID: 8217377

Claim:
A device ( 1 ) for measuring the width (B) and/or position of a metal strip ( 2 ) or slab, which has at least two measuring systems ( 3 , 4 ), one on each side ( 5 , 6 ) of the metal strip ( 2 ) or slab, where each measuring system ( 3 , 4 ) has a sensor ( 7 ) designed to detect the lateral edge ( 8 , 9 ) of the metal strip ( 2 ) or slab, and where the sensor ( 7 ) is mounted on a moving element ( 10 ) that allows it to make translational movements in a direction (Q) transverse to the longitudinal, horizontal direction (L) of the metal strip ( 2 ), wherein the sensor ( 7 ) is mounted on a swiveling supporting arm ( 11 ) of the moving element ( 10 ), where the axis of rotation ( 12 ) of the swiveling support arm ( 11 ) points vertically in the direction (N) normal to the longitudinal, horizontal direction of the metal strip ( 2 ) or slab, and where at least one linear actuator ( 13 , 14 ) is provided for moving the moving element ( 10 ) and possibly the supporting arm ( 11 ).
