What Causes Forming Fabric Edge Cracking?

FAQ

Root causes of forming fabric edge cracking:

1. Excessive deckle pressure — Too much force on fabric edges from deckle boards
2. Roll misalignment — Creates high edge tension; verify with laser alignment
3. Uneven cross-machine tension — One edge bearing more load than the other
4. Fabric-to-frame friction — Contact with machine frame or stationary elements
5. Chemical attack from edge shower chemicals
6. Fatigue in unsupported fabric spans between rolls

Damage Type Diagnosis:

• Clean mechanical cuts = alignment or friction issue
• Multiple small fatigue cracks = tension or support problem
