Thin and flexible continuous medium is called Web. The Web is used in many products such as paper or high-tech films. In addition, Web-based solar cells in environmental and energy field have been actively developing. Therefore, the Web is required to improve productivity because demand is anticipated to expand further. The Web is taken up in final roll supported by many rollers, is transferred. The wound roll defects such as slippage or wrinkling occur in the process such as keeping and shipping and cause major economic losses, because the wound roll is affected by temperature environments. It is known that internal stress state depend on the roll defects, therefore, accurate measurement and calculation of internal stress under various temperature conditions in wound roll are required. In this study, we compared the measurements with the analysis in wound roll internal stress under various temperate changes. As a result, theoretical results show good agreement with the measured data.
