A measuring roller for detecting the flatness deviation of a belt-like article and a method for detecting the flatness deviation of the belt-shaped article

摘要

The measuring roll (4) has a longitudinal axis and a sensor arranged in a recess of the measuring roll. The sensor is provided for generating a measuring signal depending on a force applied on an outer surface of the measuring roll. A first temperature sensor is arranged at a first distance in a radial direction away from the longitudinal axis. A second temperature sensor is arranged in a second distance different from the first distance in the radial direction away from the longitudinal axis. An independent claim is included for a method for determining flatness deviations of a band-like material.
