Roll marks, roll eyes, and uneven luster. It is mainly rollers caused by aluminium foil defects, divided into point, line, surface three. The most notable feature three cycles appear. The main reasons for this defect are: incorrect grinding of the roll; foreign material damage to the roll: incoming defects imprinted roll; roll fatigue; inter-roll impact, slipping and so on. All the factors that can cause surface damage to the rolls can be harmful to aluminium foil rolling. Because the aluminium foil rolling roll surface finish is very high, the slight unevenness of the gloss will also affect its surface condition. Regular cleaning of the mill, to keep the mill clean, to ensure that the normal work of the roller cleaner, regular roller replacement, reasonable grinding, are to ensure that the aluminium foil rolling surface uniformity of the basic conditions.

Wrinkle. Due to the serious bad shape of the plate, wrinkles will be formed when the aluminium foil is rolled or unfolded, the essence of which is that the tension is not enough to make the foil surface flat. For the tension dimension 20MPa device, the foil surface of the plate shape shall not be greater than 30I, when greater than 30I, it is bound to wrinkle. As the rolling of aluminium foil is often subjected to greater than the subsequent processing of tension, some in the rolling of the mere manifestation of the plate shape is bad, including roll grinding is not correct, the roll type is not right, the incoming plate shape is bad and adjust the plate shape is not correct.
