Automatic Needle Felt Strip Slitting Machine

Automatic Needle Felt Strip Slitting Machine

Automatic Needle Felt Strip Slitting Machine for Filter Bag Manufacturing

🟠A dedicated solution for high-efficiency strip preparation in industrial filter bag production.

This machine converts wide rolls of needle-punched felt into Bead / Profile Tape, Reinforcement Strips, and Seam Binding Strips with stable width accuracy, clean edges, and neatly rewound output rolls—ensuring consistent downstream sewing and snap-band assembly.

Why This Machine Matters

⚠️ Traditional Method

The Problem with Traditional Felt Strip Cutting

⚠️ Traditional Manual Method

• Requires 2 operators (one feeding, one collecting)

• No rewinding system → strips exit loose, tangled, and disorganized

• Manual feeding required for the next sewing step, resulting in low efficiency and quality variation

• Strip width varies by operator and shift → unstable seam quality

• High material waste, especially with Aramid / PPS / PTFE technical felts

• Cut felt strips are difficult to organize, store, and transfer to sewing operations

The slitterd  felt strips usually become messy to organize and store,and it often requires manual handling

to roll and manual handling to sewing process  

🟠The Automated Solution

Upgraded to Automatic Needle Felt Slitting Machine

Manual roll loading → Automatic feeding → Multi-blade synchronous slitting → Air-shaft automatic rewinding

Key Improvements

• ✅ Only one operator required

• ✅ Strips exit as neatly wound rolls, ready for sewing or snap-band forming

• ✅ Consistent and repeatable strip dimensions across shifts

• ✅ Reduced waste and improved utilization of high-value filter media

Key Features of the Automatic Needle Felt Slitting Machine

🟠 Automatic Feeding System
Maintains uniform tension and alignment to ensure width accuracy.

🟠 Multi-Blade Synchronous Slitting
Cuts multiple strips simultaneously for high throughput.

🟠 Air-Shaft Automatic Rewinding
Produces compact, clean rolls that are easy to change and transport.

🟠 Adjustable Strip Width (25–90 mm)
Supports production of Bead/Profile Tape, Reinforcement Strips, and Seam Binding Strips from a single setup.

🟠 Tension & Alignment Control
Prevents stretching, fraying, or distortion of sensitive technical felts.

🟠Heavy-Duty Industrial Frame

Designed for continuous industrial operation with low maintenance requirements.
