Introduction
SSB (Sheet Support Binder) triple layer forming fabric represents the pinnacle of paper machine clothing technology. For paper manufacturers operating high-speed machines or producing demanding paper grades, SSB fabrics deliver unmatched performance.
What Makes SSB Different?
Unlike single or double layer fabrics, SSB fabrics feature three independent yarn systems:
- Top layer (sheet side): Fine mesh for superior fiber support
- Bottom layer (machine side): Robust construction for wear resistance
- Binder yarns: Connect the two layers while allowing independent weave structures
5 Key Benefits
1. Superior Sheet Quality
The fine top layer provides excellent fiber support and minimal wire marking, resulting in a smoother, more uniform paper surface. This is particularly important for printing and writing grades where surface quality directly impacts printability.
2. Maximum Drainage Capacity
The independent bottom layer is designed specifically for drainage, with higher open area than the top layer. This dual-layer approach optimizes both fiber retention AND water removal simultaneously.
3. Extended Service Life
The robust bottom layer is engineered for wear resistance, while the top layer focuses on sheet quality. This separation of functions means each layer can be optimized without compromise, resulting in 50-100% longer running life compared to double layer fabrics.
4. Excellent Dimensional Stability
The SSB structure provides exceptional cross-machine and machine-direction stability. This means:
- Consistent performance throughout the fabric life
- Reduced edge curl and wrinkling
- Better seam integrity
- More uniform paper properties
5. Versatility Across Paper Grades
SSB fabrics can be customized for virtually any paper grade:
- Tissue: High drainage for 2,000+ m/min speeds
- Fine paper: Ultra-smooth surface for coating
- Packaging: Robust construction for heavy weights
- Specialty grades: Custom configurations available
When Should You Upgrade to SSB?
Consider upgrading to SSB triple layer fabric if:
- Your machine speed exceeds 800 m/min
- You produce high-quality printing or writing grades
- You experience frequent fabric changes due to wear
- Sheet quality issues are impacting your product value
- You want to reduce cost per ton of paper produced
Return on Investment
While SSB fabrics have a higher initial cost, the total cost of ownership is typically lower due to:
- Longer running life (fewer fabric changes per year)
- Reduced downtime for fabric changes
- Better paper quality (higher sales value)
- Lower energy consumption (better drainage efficiency)
