FAQ

Common causes of press felt edge wear:

  1. Deckle board friction — Adjust gap to 3-5mm from felt edge
  2. Roll misalignment — Annual laser alignment recommended, especially for edge-loaded rolls
  3. Uneven cross-machine tension — Verify uniform tension profile across width
  4. Vacuum box edge seal problems — Inspect and replace worn seals
  5. 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
