Solutions to problems that occur when the film slitting machine cuts the film

During the operation of the slitting machine, as the film winding diameter increases and the tension gradually becomes smaller, the attenuation rate should be reduced to maintain constant tension. On the contrary, when the tension gradually increases as the winding diameter increases, the attenuation rate should be increased at this time.
When the diameter of the film roll increases and the contact pressure begins to increase, the roller pressure should be reduced. The hardness of the film roll depends on how much air enters the film during winding. When the film roll is soft, the winding tension should be increased, and when it is hard, the winding tension should be reduced.
In addition, the operations of the slitting machine when it is stopped, such as changing rollers, adjusting knives, changing film rolls, conjunctival treatment, etc., will also affect the quality of the film.
Poor handling of each process may cause trouble and waste of materials in the next process. Therefore, how the slitting machine cuts the film is a comprehensive topic, and it is necessary to constantly sum up experience in practice to bring out the best state of the slitting equipment.
