The web is a continuous thin film material, is mass-produced by roll-to-roll (R2R) production method. R2R conveys the web by many rolls, but problems such as troughs and creases occur. In addition, when the heat treatment process is included, the internal temperature changes greatly, and wrinkles may occur due to the shrinkage of the web. Hashimoto et al. established a wrinkle prediction theoretical model assuming steady state, but thermal stress was not considered. Therefore, in this paper, for the purpose of confirming the cause and position of wrinkles caused by heating, we conducted wrinkle generation experiments during heating and transportation, and clarified the improvement policy of the prediction model.
