Abstract
A web is a continuous, flexible materials such as paper, plastic film, metal foil, textiles etc. Web wrinkling is a problem which plagues the web process industries. Most webs are very thin and prone to buckle or wrinkle. The effects of wrinkling can range from compromised product quality to down time of a processing operation, leading to less profitability in the manufacturing operation. The web wrinkles which will be treated in this paper are those that can be affected by roller misalignment and friction characteristics between web and roller. It is shown how web wrinkles can be predicted and ultimately avoided in manufacturing operations. Prediction method is presented with experimental verifications.
