Wrinkles, press section

1. Maintain basis weight uniformity.
— ensure that there are no “thin” areas.
2. Avoid sagging edges at couch.
— keep edges dry and with the same formation as rest of sheet.
— ensure that end seals of couch box do not leak.
3. Do not allow wrinkles in felt.
4. Crumbs tend to wrinkle the felt.
— crumbs can be scraped off outside rolls, but they must be washed off inside rolls.
5. Keep draw tight and maintain control.
— long draws can lead to wrinkles.
6. Watch for entrapment of air between felt and paper.
7. Improve the lead to press nip.
8. See that loading system for press is not jammed.
