Why does paper wrinkle in Duplo Folding Machines?
Paper wrinkles may occur in Duplo Folding Machines if the press pressure of the folding roller is too strong. Adjust the press pressure, especially setting the press pressure of folding roller 1 weak, around 45 to 46 mm (1.77" to 1.81"). Another cause can be a deformed folding roller, in which case you should replace it.
How to fix skewed paper conveyance in Duplo Folding Machines?
If paper is conveyed skewed, it could be due to several reasons. * The left and right nip amount differs between the folding rollers, check the attached state of the reference stopper, and make the roller nip the same. * The thrust play of the folding roller drive gear is large. Adjust so that there is no thrust play. * The press pressure of the folding roller is not balanced between the left and right sides. Adjust the press pressure. * The folding roller is deformed, in which case replace the folding roller.
