Device for measuring tensile stress distribution in a metal strip

摘要

A method for measuring the tensile stress distribution over the width of the metal strip is provided. In order to measure the tensile stress in a metal strip between two roll stands or between a roll stand and a coiler or a guide roll, a force is exerted on the metal strip using a suction device and effecting a deflection of the metal strip. The deflection of the metal strip is measured and used for calculating the tensile stress distribution over the width of the metal strip.
