Short-Arm Two-Needle Cylinder-Bed Filter Bag Sewing Machine | KABORY

Industrial Filter Bag Sewing Machine for Cuffs, Bottoms, and Reinforcement Layers

KABORY’s short-arm, two-needle cylinder-bed sewing machine is purpose-built for industrial filter bag manufacturing. It delivers strong, uniform seams on cuffs, bottoms, and reinforcement layers while maintaining stable performance on multi-layer Polyester ,Acrylic ,PPS, Aramid, P84,PTFE, and woven fiberglass .

The machine maintains consistent feeding and thread tension even on challenging technical felts such as PTFE and fiberglass, ensuring clean, uniform seams with no puckering, skipped stitches, or fraying. This is essential for high-temperature and high-value filter bags used in demanding industrial environments.

It is also engineered to handle a wide range of material thicknesses. Standard needle felts are typically around 2.20 mm, while some fiberglass-blended felts can reach 3.50 mm. The machine sews both smoothly with stable needle penetration and precise stitch control across all layers

High-Precision Sewing for Multi-Layer Industrial Needle Felts

The heavy-duty compound feed system ensures smooth circular and cylindrical sewing with excellent stability. It maintains uniform stitch depth, balanced thread tension, and consistent seam formation across all industrial felt types, including PPS, Aramid, PTFE, fiberglass, and general-purpose needle felts.

This high level of control and stability makes the machine ideal for applications requiring long service life, dimensional accuracy, and leak-free seam performance.

👉 With KABORY, you get smoother workflow, stronger seams, and long-term stability — a machine purpose-built for filter bag production, delivering consistent output, fewer defects, and superior performance in demanding industrial environments.

Key Features

✅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

Double Rotary Hook System (Premium Industrial Edition)

At the heart of the sewing head is KABORY’s Premium Double Rotary Hook System, engineered for precision-critical industrial filtration applications. The dual-hook architecture provides exceptionally stable loop formation and synchronized thread control, even under continuous multi-shift operation.

Each hook operates with ultra-low friction, minimizing heat buildup and preventing thread fraying when sewing high-tenacity PPS, Aramid, or PTFE thread. The system maintains perfect hook timing and alignment across long production runs, ensuring:

• Consistent seam integrity at high speeds

• Minimal skipped stitches and extremely low breakage rates

• Superior performance on thick needle-felt materials

• Long service life compared with standard rotary hooks

Designed for high-duty industrial use, this advanced hook system elevates seam quality, production reliability, and long-term machine stability—setting a benchmark for professional filter bag manufacturing equipment.

 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: General-Purpose Machines vs. KABORY Cylinder-Bed Two-Needle Machine

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
