Robust Reference Tension Optimization in Winding Systems Using Wound Internal Stress Calculation

Presented by M'hamed Boutaous, University of Strasbourg

It is well known that the tension reference value, which a priori guarantees a good quality roll, is based on the stress generated within the roll. The tension reference is optimized by considering both the tangential and the radial stress within the roll during winding. Moreover, a dynamic stress gauge is introduced, so that it can vary during the winding process. It generally represents the limits of elastic deformations of the web. A second approach consists to optimize the tension reference gauges, i.e. maximum and minimum reference values around the optimized nominal reference curve.
