Automatic Needle felt Strip Slitting Machine for Bead/Profile Tape and Reinforcement Strips

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

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 wound output rolls, ensuring consistent downstream sewing and snap-band assembly processes

Why This Machine Matters

⚠️ Traditional Method

• Requires 2 operators (one feeding, one collecting strips)

• No rewinding system → strips exit loose, tangled, scattered across workspace

• Next sewing step requires manual feeding, causing low efficiency and quality variation

• Strip width varies between operators and shifts → unstable seam quality

• Waste increases significantly when cutting Aramid / PPS / PTFE technical felts

• 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  

🟠 Upgraded  to Automatic Needle Felt Slitting Machine

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

✅ Only 1 operator required
✅ Strips come out neatly wound, ready for sewing or snap-band forming
✅ Consistent and repeatable strip dimensions across shifts
✅ Reduced waste and improved utilization of high-value materials

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.
