Needle Felt Strip Slitting Machine

Designed for Efficient Slitting of Filter Bag Strip Components

In filter bag manufacturing, the slitting of long, narrow strips is a foundational step — whether for cuff production, reinforcement layers, or seam alignment strips.

Why Upgrade from Manual Cutting?

In traditional filter bag production, cutting narrow strips from large felt rolls typically involves:

• Manual feeding of felt rolls
• Hand-marking widths
• Scissor or handheld blade cutting
• No rewinding system
• Requires 2 or more operators

This outdated approach results in:

• Uneven edges and inconsistent widths
• Disorganized output
• High labor intensity (often 2–3 workers per shift)
• Material waste and low repeatability

Our automatic slitting machine eliminates these inefficiencies. With one operator, it delivers clean, consistent slitting and neatly rewound strips—freeing up floor space, improving output, and dramatically cutting labor.

Key Features

• 🎯 Specialized for Strip Cutting
  Cuts uniform strips from needle felt rolls for use in cuffs, reinforcement layers, and other filter bag components.
• ⚙️ Smooth Mechanical Feeding System
  Ensures consistent material flow without wrinkles or drag, critical for long, continuous rolls.
• ✂️ Multiple Blade Support
  Equipped with several circular blades to simultaneously cut multiple strips at adjustable widths.
• 🧰 Adjustable Blade Spacing
  Easy-to-adjust spacing system allows rapid format changeover without tool replacement.
• ♻️ Automatic Rewinding System
  Neatly rewinds each finished strip into independent rolls, keeping output clean and organized.
• 🏭 Compact, Heavy-Duty Structure
  Stable steel construction reduces vibration, improves precision, and ensures long-term reliability.
