three. Irregular end faces
The end face irregularity refers to the unevenness of the end face which occurs when the film width is constant. The end face is generally in two forms: one is that the end faces are irregularly jagged, and the other is a regular wave-shaped irregularity.
1. Causes and countermeasures for uneven end faces:
1 The cutting parameters are not well adjusted. For example, if the cutting speed and the sheet/pressure are poorly matched, the sheet/pressure curve should be set according to the slitting speed;
2 abnormal vibration of the cutting device, overhaul;
3 divided and unwinding rolls are unbalanced and adjusted;
4 The parameters of the winding arms at both ends are inconsistent, and the force distribution of the winding process affects the flatness of the end face, usually the wavy end faces are not aligned and overhauled;
5 The influence of film properties, such as smoothness, etc., Ts, Pm and other models are more prominent, and the cutting parameters should be set according to different film characteristics;
6 film thickness is uneven;
7 Wrinkling during the slitting process will also cause unevenness of the end face and adjust the flattening film;
8 If the film is too static, improve the electrostatic properties of the film or check if the static eliminator of the slitter is invalid.

nine. Scratch

     In addition, sometimes scratches due to slitting are difficult to detect by the naked eye, but scratches (scratches) will attenuate the corona value of the product. According to experience, the corona value is reduced by about half in the normal cutting process. Dyne, when the corona values ??differ by more than one dyne before and after cutting, the reasons for the cutting process, such as the speed ratio of the driving roller, the quality of the sand skin, the condition of the sipe roll, etc., should be checked to eliminate the influence. .
     It is worth mentioning that there is a kind of abrasion that is caused by the slitting process, but it is mainly caused by the cutting factor. It is mainly that the mother roll is too loose, and the product of the loose part is horizontally or vertically tilted during the slitting process. While scratching the film surface, it is found that the phenomenon is to install the upper splint on the mother roll for positioning, and secondly, the cutting speed should be properly controlled, and the influence of the quality of the mother roll on the cutting quality can be improved as much as possible.
