厚み分布を考慮した巻取りロールの内部応力解析と巻取り条件の最適化

抄録

Various web products are often rolled into rolls for ease of storage and transportation. However, these wound rolls are based on experience in testing web thickness distribution, tension and nip loads at production sites. Therefore, it is important to predict defects in advance when the web is wound up. In this study, we conducted an internal stress analysis of the winding conditions and optimized the winding conditions in consideration of the thickness distribution and examined the conditions under which the winding roll does not malfunction.
