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.

Fives. Multilateral
Although the polygon and the end face are not the same as the faulty end faces of some layers of the film roll, the two are different. The unevenness of the end face is the jagged phenomenon that occurs when the film width is not changed, and the multilateral product The film width is slightly wider than the normal size.

1. Multilateral impact on quality of use
The impact of multilateral use on the end is basically the same as that of the end face, mainly to track the problem of alignment and the impact on the appearance of the product.
