Widthwise variations in web properties and wound roll structure

Olsen, J. E.
Abstract
Widthwise variations in web properties affect wound roll structure. Cole & Hakiel published a two-dimensional model in 1992 which took widthwise variations in web thickness into account. Based on this publication a model accounting for widthwise variations in thickness, MD-and ZD-stiffness and frozen-in strains have been derived. The model enables calculations of wound roll stresses and outer roll radius. The model is presented and results of different effects discussed.
