The cause of poor coating gap of PE Protective film coater (2).

(3) Protective film coater equipment: coating-back roller distance.  The speed at which the roller is applied when the back roller pops open. The diameter of the back roller. Back roller surface material. The back roller is deformed. The parallelism of the back roller to the coating roller. The back roller is not parallel to the front roller of the oven. Tension in operation

2. The head and tail of the Protective film coater are not parallel

(1) Material: The gravitational force on both sides of the substrate is uneven

(2) Tension adjustment roller adjustment state
