If you run a leather tannery, you know the frustration. Your sammying machine (also called a squeezing or dewatering machine) isn’t removing enough water from wet blue or crust leather. The result? Longer drying times, higher energy bills, and uneven leather quality.

Worse, your felt belts lose tension, shrink, or burn through too quickly — especially when processing heavy loads in hot, acidic conditions.

This is not just a maintenance issue. It’s a production bottleneck.

The right felt belt changes everything. And that’s where Annilte comes in.

Why Standard Felt Belts Fail in Wet Conditions

Most standard wool or blended felts are not designed for the continuous pressure, heat, and chemical exposure inside a sammying machine. Over time:

• Fibers soften and collapse, reducing water absorption
• Heat from friction causes shrinkage or melting
• Acidic leather chemicals degrade stitching and backing

For tanneries in the US, Europe, and Southeast Asia, three things matter most: consistent dewatering, heat resistance, and long service life.

Annilte has engineered a better solution.

Annilte Nomex Felt Belt: Built for Heat, Pressure, and Acid

Our Annilte Nomex Felt Belt for Sammying Machines uses a meta-aramid fiber structure (Nomex™-equivalent technology) with a proprietary needle-punched design. Here’s what that means for your leather line:

1. Superior Water Extraction Rate

The felt’s open fiber matrix and calibrated density create strong capillary action. Water is pulled away from the leather surface and released quickly through the press rolls.

Result: Wet blue moisture content drops from ~60% to under 48% in a single pass — faster drying and less roller slippage.

2. Heat Resistance Up to 400°F (204°C)

Friction heat inside a sammying machine can exceed 200°F. Regular felts start to soften at 250°F. Annilte Nomex felt maintains fiber stiffness and porosity even at 400°F.

No melting. No glazing. No sudden belt failure mid-production.

3. Acid & Chemical Tolerance

Leather processing involves residual acids (sulfuric, formic) and tanning agents. Our felts undergo an anti-hydrolysis treatment that resists fiber embrittlement — a common failure point in standard belts.

4. Improved Structural Stability

We modified the traditional scrim (base fabric) design by adding a high-temp monofilament layer between the needled felts. This reduces longitudinal stretch by over 30% compared to generic felts.

Technical detail: Our R&D team increased the needling punch density from 180 to 220 punches/cm². This locks the fibers tighter, preventing delamination while maintaining water flow.

Real-World Performance in Key Markets

Tanneries in Southeast Asia (high humidity, aggressive dewatering) report two seasons of trouble-free use. European and US customers note fewer unscheduled stops and lower felt replacement costs.

Which Annilte Model Fits Your Sammying Machine?

We offer two standard series:

• AN-NX200 – General duty, 6–8mm thickness, for roller widths up to 2000mm
• AN-NX250H – Heavy-duty, 8–10mm thickness, reinforced edges for high-pressure presses

Both are available with endless or open-ended joining, and we can cut to your exact roller length and width.
