Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

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.
