Automatic Filter Bag Cutting Machine

Automatic Filter Bag Cutting Machine-Advanced automated cutting system designed for industrial filter bag production.
It delivers precise, consistent cutting for cuffs, bottom discs, reinforcement layers, and felt strips across all technical filter materials.
By replacing traditional manual and punch-cutting methods, this machine ensures cleaner edges, higher repeatability, and significantly improved productivity.

High-Precision Multi-Function Cutting System for Filter Bag Components

• Cuff fabric for bag top openings
• Bottom discs in all diameters
• Reinforcement layers (100 / 150 mm or custom sizes)
• Felt strips for cuffs, discs, and structural sealing
• Pre-cut parts for liquid filter bag production

Replacing Multi-Station Manual Cutting

In traditional workshops, these components require multiple stations and at least six workers, involving repeated measuring, template marking, hand-cutting, and disc punching.

 This automated system consolidates the entire workflow into a single machine operated by one person — dramatically reducing labor demand, improving consistency, and boosting factory competitiveness.

What materials can this machine cut?

• Needle-punched felts

• Fiberglass filter media

• Hybrid fiberglass felts

• PTFE Needle Felt 

• Aramid, PPS, PTFE,polyester, polypropylene, and their blends

High-Precision Cutting System for Industrial Filter Bags ,with  servo motion control and digital shape programming, it delivers consistent, clean, and repeatable cuts of any 2D shape without physical dies, setup changes, or manual intervention.

Smart Nesting Software (Patent-Pending)

Our system features a proprietary intelligent cutting layout optimizer, developed to maximize fabric usage:

• Automatically arranges cuffs, discs, and reinforcement shapes

• Supports mixed-size production layouts

• Optimizes cutting paths for up to 85% material utilization

• Reduces waste, tooling cost, and fabric stock needs

• Improves output rate with zero manual nesting effort

This cutting optimization system makes the machine not only a high-speed cutter but a cost-saving, intelligent manufacturing solution — ideal for high-volume, multi-shape production environments.

Why This Filter Bag Cutting Machine Boosts Factory Efficiency

In most filter bag factories today, cutting cuffs, discs, and reinforcement layers involves:

• Hand-marking fabric with cardboard or wooden templates

• Scissor or die cutting using fixed jigs

• Repetitive manual measurements with high error risk

• Use of manual punch machines to cut round discs, one at a time

• At least 6 full-time workers across 3–4 separate workstations

This process is time-consuming, inconsistent, injury-prone, and space-inefficient — and it directly impacts final product quality.

Why This Machine Improves Factory Competitiveness

✅ One machine replaces 6+ workers
✅ Eliminates tool storage, template errors, and die changeover
✅ Boosts productivity and dimensional accuracy
✅ Reduces floor space usage and improves workplace safety

Real-World Cutting Performance (Aramid 350 g & Fiberglass&PTFE Felt)

• Bottom Discs (Ø135 / Ø150 / Ø165 mm, mixed): ≈ 2.0 s/pc (validated)

• Bottom Discs (Ø120 mm, optimized path): ≈ 1.5 s/pc

• Reinforcement Layers & Cuffs (Ø120–165 mm): ≈ 0.25–0.35 s/pc (>150 pcs/min)

• Material Utilization in typical jobs: ≈ 82% (up to 90% with smart nesting)

Note: The machine’s maximum linear speed (up to 1800 mm/s) reflects axis capability.
The cycle times above are full, real production cycles including acceleration/deceleration, piercing, and inter-part transitions on heavy technical fabrics (aramid & fiberglass).
