The five components of the coating machine
The unwinding operation of plastic film requires that the film keep constant tension all the time. Too much tension will lead to longitudinal wrinkles and vice versa, which is not conducive to the coating of adhesives and the compounding of printed matter. In order to maintain proper tension, the unwinding part is usually equipped with tension control devices, such as mechanical friction disc clutch, AC short motor, magnetic powder clutch and so on.
