Webs (such as paper, plastic film and meal sheets …etc) are wound onto rolls for distribution, processing, and operations. In the winding process, tension is one of the most important parameter for preventing the wound roll defects such as the star defect's and slippage which are detrimental to roll quality. In production field, it well known experimentally that linearly-decreased winding tension has the affects of preventing the wound roll defects. However, this tension pattern is not necessarily adapt to various types of conditions. On the other hand, Hashimoto present the optimization method of winding tension which is expressed by 3rd order spline curve for preventing the wound roll defects. Thus we designed a wound testing machine to determine in-roll stress under deferent tension conditions. As a result, the predicted results by several tension conditions are compared with the measured data. Good agreements are seen between them.
