Analysis of the cause of the tearing of the pole piece during the operation of the coater

1. The belt is not correct, and the additional pulling force is increased to make the foil strip break in the weak place;

2, the sampling caused damage, resulting in a significant drop in the tensile strength of the foil strip;

3. The tension is too large, unstable, and there is a sudden change;

4, the wind volume is abrupt, the distribution is severely uneven;

5. The temperature is abrupt, which has a great influence on the strength of the aluminum foil;

6, the foil strip is of poor quality and has a gap at the edge;

7. The foil strip is seriously deviated and is cut off by the edge of the roll end.
