FAQ
Root causes of forming fabric edge cracking:
- Excessive deckle pressure — Too much force on fabric edges from deckle boards
- Roll misalignment — Creates high edge tension; verify with laser alignment
- Uneven cross-machine tension — One edge bearing more load than the other
- Fabric-to-frame friction — Contact with machine frame or stationary elements
- Chemical attack from edge shower chemicals
- 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
