High-Precision Roll-to-Roll Slitting System for Large-Format Filter Materials

Precision Slitting Machine for Needle Felt and Fiberglass Media

Our slitting machine is engineered not only for needle felt but also specially optimized for fiberglass-based filter media — addressing the unique challenges of fraying, misalignment, and edge damage that occur during cutting.

By combining advanced tension control, real-time deviation correction, and specialized roller technology, the system delivers clean, consistent, and high-speed slitting results across a wide range of filtration materials.

Key Technology Advantages

✅ Advanced Tension Control System
Maintains stable tension throughout the entire slitting process, ensuring precise widths and preventing fiberglass edge distortion.

✅ Magnetic Powder Clutch (Dual-End)
Installed at both winding and unwinding ends, stabilizing material feed and rewinding uniformity.

✅ Hydraulic Auto Loading with High-Precision Deviation Correction (±200 mm)
Automatically lifts and aligns rolls during unwinding.
The deviation correction system tracks fabric movement in real-time and corrects within ±200 mm, keeping rolls perfectly centered. This minimizes edge waste, improves slit accuracy, and reduces operator intervention.

✅ Air-Shaft for Unwinding & Rewinding
Equipped with inflatable air-shafts, enabling fast roll changes, stable clamping, and smoother rewinding. This design reduces downtime and ensures uniform material handling, especially critical when processing wide fiberglass rolls.

✅ Pneumatic Blade System
Air-pressure-controlled blades with individual pressure gauges apply consistent downforce, ensuring clean edges even on multi-layer fiberglass rolls.

✅ Nylon-Coated Rollers – For Fiberglass Protection
Most equipment manufacturers still rely on bare steel rollers. Under high-tension and large wrap angles, this design often causes fiber scratches, broken filaments, and frayed edges.
At KABORY, we use polyamide (nylon) coated rollers in critical positions. With low friction and micro-elastic cushioning, they:

• Reduce fiber damage

• Maintain smooth traction

• Deliver cleaner edges with less dust generation

💡 This innovation extends the life of fiberglass fabrics, minimizes rework and waste, and reduces dust-handling costs.

✅ Rewinding Lift System
Supports precise rewinding, reduces operator labor, and improves safety.

✅ Industrial-Grade Frame & Ergonomic Design

Stable heavy-duty structure with low vibration, designed for continuous operation and reduced operator fatigue.
