Filter Bag Needle Felt & Fiberglass Slitter

Precision Slitting Machine for Needle Felt and Fiberglass Media

Engineered for Precision Slitting of Fiberglass and Needle Felt

While traditional slitters were primarily designed for needle felt, the growing demand for fiberglass-based filter media has raised the bar for slitting precision and stability.

Fiberglass fabrics — especially uncoated types — are prone to fraying, misalignment, and edge damage during slitting. Our machine addresses these challenges with:

• ✅ Advanced Tension Control – prevents fiberglass edge loosening or distortion
• ✅ Real-Time Deviation Correction – keeps fabric aligned during the entire unwinding process
• ✅ Pneumatic Blade System – applies consistent pressure with individual gauges, ensuring clean edges even on multi-layer fiberglass rolls
• ✅ Nylon-Coated Rollers – reduce abrasion and fiber damage

This machine is not only suitable for needle felts but also specially optimized for cutting fiberglass filter fabrics — which demand far stricter handling and alignment standards.

Key Features

• 🧵 Advanced Tension Control System
  Maintains consistent tension across all stages, ensuring clean edges and accurate slit widths — especially important for fiberglass without PTFE membrane.
• 🌀 Magnetic Powder Clutch (Dual-End)
  Installed at both winding and unwinding ends to stabilize material tension and improve rolling uniformity.
• 🛠️ Hydraulic Auto Loading with Auto Deviation Correction
  Automatically lifts and aligns rolls during unwinding. The deviation correction system tracks and adjusts in real-time to keep material centered.
• 🏗️ Rewinding Lift System
  Ensures precise rewinding with controlled lift support. Reduces labor, enhances alignment, and improves operator safety.
• ⚔️ Pneumatic Blade System
  Heavy-duty slitting system with air-pressure controlled blades and individual pressure gauges for optimal downforce and cutting precision.
• 🏭 Industrial-Grade Frame with Ergonomic Design
  Stable and durable structure supports long-term production with minimal vibration and reduced operator fatigue.
