In multiple vertical folding. The corners of the page (near the intersection of the fold lines) are easily wrinkled. To avoid this phenomenon. It must take corresponding preventive measures.
Common reasons are:
The 1 folding sequence is unreasonable, which causes the folder folding pressure to be too high, causing the paper at the hinges to wrinkle.
2 folding process is unreasonable. The air is trapped inside the signature and cannot be discharged smoothly, affecting the folding effect. For example, two parallel folds are performed on the page first, and then two parallel folds in the vertical direction. This solution can easily cause air stagnation inside the signature. But if you change the previous two parallel folds into fan-shaped folds, you can get out of trouble.
3 The speed of the hybrid folder is too high, which increases the pressure on the paper during folding. Generally speaking. The heavier and lighter papers must use lower folding speeds.
4 The replacement paper type sometimes receives better results. For example, recycled paper has short fibers and low strength. The possibility of wrinkling at the corners is even greater, if you change to paper with a better quality grade. You can greatly improve the folding effect of the automatic folding machine.
