Frequently asked questions about protective film coaters (4).

Handling scheme of protective film coater: recuperation channel, winding tension of the second unwinding unit; Replace better quality composite substrates; Carefully bond new and old material belts; The recuperation winding tension is large and the average of the winding pressures on both sides.  Protective film coating movement wrinkle (inner wrinkle) refers to the appearance of wrinkles in the area close to the core tube inside the composite coil. In the mechanical production of protective film coater, the probability of core wrinkle attack and the influence of formation are greater than that of dry composite production.
