Abstract

A system and a method for measuring and determining flatness of a strip (1) of rolled material. Said system is comprising a measuring roll (2) having a cylindrical central structure (41) having a number of measuring devices for force/pressure registration. Said devices is generating measurement output signals (Upi) depending on the contact between the strip and the measuring roll (2), wherein said measurement output signal (Upi) comprises a force component signal (UFi). Said system also comprises a Flatness Determination Unit (56), said unit being arranged for calculating the flatness ( DELTA sigma 1) of the strip based exclusively on signals derived from measurement output signal (Upi) values generated by said measuring devices and information about the values of the width and thickness of the strip (1). The system is continuously determining the Wrap Angle ( alpha ) from at least one measurement output signal (Upi) and automatically compensating for a changing Wrap Angle ( alpha ). The present invention also provides a computer program product, a computer data signal and a flatness determination signal for accomplishing said objects of the invention.
