A large number of roller wear materials require not only flexible and free rotation, but also a good dynamic and static balancing process.
Imagine if each feed roll prints a small resistance, gravure press synchronization and electrostatic resistance, it is difficult to guarantee printing accuracy.
Tension control
When the feeding part needs to be done: film, the tension is small; the film is small and tense. Accept job requirements:
The film is small, the tension is small; the film is tight. When the film is unwinded, the film is reduced in tension, and the film is gradually reduced.
Printing is printing, printing paper or film, always want to maintain consistent tension, tension feeding or film is smooth, tension is acceptable for receiving paper or film. The printed version will not run and the registration accuracy will be maintained.
