Model for the prediction of wound roll dishing
Abstract
Historically, wound-roll models have been used to predict stress levels which develop within winding and wound rolls. To gain maximum benefit from these models, stresses must be incorporated into defect or failure models. This paper focuses on the development of a wound-roll dishing model. Caliper nonuniformity in both the width and the length direction is incorporated into the model. The effect of some of the important conveyance issues is also included in the model. An experiment is described and the results compared to the analytical predictions. Finally, the model is used to study the effects of process parameters on the level of wound roll dishing.
