Automatic Needle Felt Strip Slitting Machine
Automatic Needle Felt Strip Slitting Machine designed to convert wide rolls of needle-punched felt into Bead/Profile Tape, Reinforcement Strips, and Seam Binding Strips.
Performs automatic feeding → multi-blade slitting → air-shaft rewinding, ensuring consistent strip width, neat roll output, and one-operator stable production.
Description
Automatic Needle Felt Strip Slitting Machine
Automated Slitting System for Reinforcement, Bead/Profile Tape, and Seam Binding 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
🟠 Upgraded With This 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
🟠 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.
