At this time, the third roller is subjected to force to avoid excessive tension on the PET film. The connecting piece sinks and the spring is deformed under force to reduce the tension on the surface of the PET film. When the PET film moves to the first water absorption roller and the second water absorption roller, the moisture on the surface of the PET film can be absorbed to meet the factory standards.
