The folding machine folds the organ with four fences. Why can't the third and fourth discounts come out? Why does it wrinkle when it comes out?

1,。 It is possible that the gap between the third and fourth grid plates is too small. When the folded paper is thick, it is necessary to adjust the gap between grid plates, especially the third and fourth grid plates, during organ folding. 2. The gap between the grating opening and the folding roller is not suitable. Organ folding, by the third and fourth folding, is already very thick, and the gap between folding rollers is relatively large. At this time, it is necessary to pay attention to the gap between the grating opening and the folding roller. 3. Check whether the paper pad between the folding rollers is correct.
