FAQ
Common causes of press felt edge wear:
- Deckle board friction — Adjust gap to 3-5mm from felt edge
- Roll misalignment — Annual laser alignment recommended, especially for edge-loaded rolls
- Uneven cross-machine tension — Verify uniform tension profile across width
- Vacuum box edge seal problems — Inspect and replace worn seals
- Felt width instability — Check for width fluctuation during operation
Diagnosis by damage type:
- Mechanical damage (clean cuts) = alignment/friction issues
- Fatigue cracks (multiple small cracks) = tension/support issues
