Long Arm Filter Bag Sewing Machine

📌 Industrial Long Arm Filter Bag Sewing Machine – Overview

This long arm two-needle cylinder bed filter bag sewing machine is engineered specifically for tubular bag structures and circular bottom closing.
The extended arm length provides a large working space, while the rotating cylinder-bed enables smooth and precise sewing of round bag bottoms.
A compound feed mechanism ensures stable feeding on multi-layer, high-temperature technical felts, including PPS, Aramid, PTFE, and Fiberglass.

Applications of the Long Arm Filter Bag Sewing Machine

Reverse air filter bags
Large-diameter fiberglass filter bags
Ventiducts and insulation sleeves
Circular bottom closing and reinforcement seams

✅ Key Features of the Long Arm Filter Bag Sewing Machine

▌ Extended Long-Arm Workspace (850mm / 1270mm)
The extended long-arm design provides ample maneuvering space for large and long filter bags, improving sewing stability and operator efficiency during tubular and bottom-closing operations.

▌ Two-Needle Parallel Lockstitch

The two-needle configuration forms reinforced parallel seam lines, ensuring airtight sealing and long-term structural durability required in industrial filter bag applications.

▌ Rotating Cylinder-Bed Design
The rotating cylinder-bed allows angle-adjusted sewing access to round bag bottoms and circular closures, reducing fabric distortion and improving seam accuracy.

▌ Compound Feed Mechanism
The synchronized movement of the needle, presser foot, and feed dog ensures smooth, consistent feeding when sewing thick, multi-layer felts used in high-temperature filtration.

▌ Large Vertical Japanese Rotary Hook

Japanese imported large vertical rotary hook for filter bag sewing machine — Japanese-imported KABAN large vertical rotary hook, designed for stable, continuous sewing of high-temperature filter bag materials.

This machine is equipped with a Japanese KABAN large vertical rotary hook, a critical component for stable, long-duration industrial sewing.

It ensures smooth thread control on PPS, Aramid, PTFE, and fiberglass felts, effectively preventing skipped stitches, thread breakage, and rework during continuous production.

Rotary Hook System Comparison in Filter Bag Sewing Machines

Item	Standard Rotary Hook	Japanese KABAN Large Vertical Rotary Hook
Precision & Wear Stability	Precision decreases after extended use, hook path may shift	High-precision ground hook path maintains long-term stability and alignment
Thread Compatibility	Sensitive to high-tenacity PPS / PTFE / Aramid thread, may cause friction or skipped stitches	Designed for high-strength filter bag thread, ensures smooth and stable tension control
Continuous Sewing Performance	Heat buildup during continuous operation can lead to thread fraying or breakage	Low heat generation and low friction maintain stable sewing during multi-shift production
Reliability in Industrial Production	Requires frequent tension adjustments and occasional re-stitching	Very low failure rate, supports uninterrupted sewing and consistent seam quality
Service Life	Typically replaced every 6–12 months	2–4 years of stable performance under industrial workload

Why the Rotary Hook Determines Real Productivity

In filter bag production, real productivity is not defined by maximum sewing speed, but by whether the machine can run continuously without skipped stitches or thread breakage.

The Japanese KABAN large vertical rotary hook is the core reliability component enabling stable, multi-shift production.

Workflow Efficiency and Operator Assist Functions

Energy-efficient servo motor
Automatic needle positioning
Automatic backtacking reinforcement
Automatic presser foot lift

These features reduce operator fatigue and support continuous multi-shift industrial production.
