Description
Kabory Two Needle Filter Bag Sewing Machine
Short-Arm, Two-Needle Cylinder-Bed Design — Purpose-Built for Filter Bags
Industry Positioning: Dürkopp, Kabory, and the Rest
In the global filtration industry, Dürkopp Adler is recognized as the gold standard for heavy-duty filter bag sewing.
Kabory ranks directly behind Dürkopp, as the only Chinese-built cylinder-bed machine designed exclusively for industrial filter bags.
Unlike other Chinese suppliers who modify garment or upholstery machines, Kabory eliminates the common weaknesses of low-cost models:
- Hesitation when sewing thick multi-layer bottoms
- Fabric puckering on overlaps
- Skipped stitches under heavy-duty loads
👉 With Kabory, you get smoother workflow, stronger seams, and long-term reliability — a machine engineered specifically for filter bag manufacturing, ensuring stable output, lower defect rates, and superior performance in demanding environments.
Why Choose Kabory?
- High-Speed & Stable Output — Up to 2,000 stitches/min with consistent stitch formation
- Two-Needle Lockstitch — Strong overlap and reinforcement seams for cuffs & bottoms
- Cylinder-Bed Short Arm — Easy maneuverability on tubular and circular seams
- Triple Compound Feed — Smooth feeding even on PPS, Aramid, PTFE, and fiberglass
Japanese Rotary Hook — Precision performance, minimal skipped stitches, and long life- Durable Construction — Cast-iron frame for vibration-free stability
🧵 Sewing Machine Comparison – Double Bottom & Reinforcement Layers
While many suppliers claim their machines can handle heavy filter bag materials, real-world results tell a different story.
Double bottoms and reinforcement seams are the most demanding stages in filter bag sewing — exactly where low-end machines fail.
Comparison Table
| Comparison Point | Low-End / General-Purpose Machines | KABORY Two-Needle Cylinder-Bed Machine |
| Stitch Quality | ❌ Skipped stitches, loose seams, uneven tension | ✅ Clean, reinforced, parallel seams — leak-free |
| Fabric Handling | ❌ Wrinkles, creases, puckering on tubular felts | ✅ Smooth circular sewing, no wrinkles, stable feeding |
| Bottom Seam Capability | ❌ Fails on 4-layer overlaps, weak seam strength | ✅ Handles thick 4-layer bottoms without skipped stitches |
| Needle Performance | ❌ Frequent needle breakage, downtime for replacement | ✅ Minimal needle breakage, stable tension, less rework |
| Output Capacity | ❌ Lower daily yield, rework often required | ✅ 30%+ higher daily output, consistent production |
| Vibration & Stability | ❌ Chain drive → high vibration, inconsistent seams | ✅ Cast-iron frame + synchronous drive → low vibration |
| Service Life | ❌ Shorter machine lifespan, higher maintenance | ✅ Proven durability, industrial-grade rotary hook |
Conclusion
👉 Double bottoms and reinforcement seams are the ultimate stress test in filter bag sewing.
Low-end machines typically fail here — skipped stitches, weak joints, costly rework, and customer complaints.
KABORY’s purpose-built two-needle short-arm machine passes this test with stable, strong seams on multi-layer heavy fabrics, making it the first choice for high-temperature, high-value filter bags (aramid, PPS, PTFE, fiberglass) — often backed by warranty contracts where failure is not an option.
Applications
- Filter bag cuffs ,Bottoms and reinforcement layers (100 mm / 150 mm wide)
- Circular bottom seams (4-layer overlaps without skipped stitches)
- Tubular seams for filtration, ducting, and insulation materials
