Precise even with low strip tension

The segment rolls were developed specially for use in stretch bending levellers. The extremely free-running measuring rings permit high-precision shape measurement even with very low strip tensions.

A rigid tubular section which forms the shaft of the roll supports several pivotably mounted measuring rings. They form the outer shell of the measuring roll over which the strip passes.

Force sensors inside the measuring rings detect the force resulting from the strip tension. The sensors have high resolution, are overload-proof and maintenance-free. The data are transmitted through the centre axis of the roll and output as a Profibus signal.
