Abstract
The demand for the metal coil coated with reflective film is rapidly increasing with the increasing demand of notebook PCs and LCD monitors. During the coating process, it is very important to regulate tension of the coil metal since fluctuation of the tension can significantly degrade quality of the product. In this study, a tension controller has been developed for winding process of LCD reflective film coating. The controller has been tested on the existing coating facilities, and the results are to be given in this paper.
