Abstract

An arrangement for measuring the flatness or planar degree of metal strips under tensile stress while being rolled, in which measuring rollers are subdivided into roller sections. Measuring elements which may be in the form of strain gages, are held in suspensions having side members which are pivotable about a fixed axis. The side members also support the individual roller sections of the measuring rollers. The measuring elements or strain gages may be fixed in the roller bearings linking the suspension and the measuring rollers. The measuring elements may also be located in a recess of the side members. Each roller section may be provided with a measuring element, and the side members, furthermore, may be connected by rigid joints to a shaft which is reinforced by a rigid box and about which the side members are pivotable. The side members, moreover, may be T-shaped and be hinged to the rigid box, while being force-linked to a cover plate containing a recess for the measuring element. The cover plate is attached to the side of the rigid box.
