Felt picking

1. Picking occurs when fibers from the sheet remain attached to felt upon its return.
— if felts are dirty, wash or replace.
2. Reset deckles that may be leaking causing feathered edge.
3. Adjust low edge profile that may make press transfer difficult.
4. Check and adjust edge shower water.
— felt edges may be carrying too much water into press nip.
5. Check stock properties.
— free up stock so less water is carried into press section.
6. Check slice area and headbox for build-up causing light areas in sheet.
— level the sheet profile.
7. True up felt and maintain proper tension.
8. Check high pressure showers and clear any plugged nozzles.
9. Ensure proper roll crowning and loading at press section.
10. Check suction rolls and clean with high-pressure water if necessary.
11. Check vacuum at suction boxes and raise if needed.
12. Check rotational position of pressure roll suction box.
