Dryer Fabric Seam Keeps Failing — Why?

FAQ

Root causes of dryer fabric seam failure:

1. Seam material unsuitable for operating temperature — Verify material grade matches your dryer temperature profile
2. Heating too fast — Follow 10-15°C per 30 minutes ramp-up protocol
3. Seam passing over stationary elements — Check seam path through dryer section
4. Uneven tension — One end stressed more than the other; verify uniform tension profile
5. Pin line wear — Insufficient lubrication of seam pin; implement scheduled lubrication
6. Seam not perpendicular to machine direction — Causes uneven stress distribution along seam

Prevention: Verify seam material, controlled ramp-up, proper lubrication schedule, and verify seam squareness at installation.
