Flexible continuous plastic films are used to produce various products, including optical films and\npackaging materials, because plastic film is suited to use in mass production manufacturing processes.\nGenerally, the web handling process is applied to convey the plastic film, which is ultimately\nrewound into a roll using a rewinder. In this case, wrinkles, slippage and other defects may\noccur if the rewinding conditions are inadequate. In this paper, the authors explain the development\nof a rewinder system that prevents wound roll defectsââ?¬â?primarily starring and telescoping.\nThe system is able to prevent such defects by optimizing the rewinding conditions of tension and\nnip-load. Based on the optimum design technique, the tension and nip-load are calculated using a\n32-bit personal computer. Our experiments have also empirically shown that this rewinder system\ncan prevent roll defects when applying optimized tension and nip-load. Additionally, inexperienced\noperators can control this system easily.
