- Oct 30, 2019-

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.
