Web Winding Simulation and Wound Roll Stresses

A method for simulating a web winding process and for predicting wound roll stresses is proposed. The simulation model is two-dimensional and is composed of a web and a core. The simulation was carried out on a FEM software to investigate effects of a slip between web layers, a core rigidity, and a leading edge of a wound web on the wound roll stress distributions. The results show that both the radial and circumferential stresses of the wound roll become extremely larger when the web layer slip is considered. While they decrease when the core rigidity becomes lower. The simulated stresses for no slip cases are compared with the results obtained by Hakiel model.
