Automatic Bead Sewing and Attaching Machine – For Filter Bag Bead/Profile Tape Processing
KABORY is the first in the industry to deliver a truly automated bead sewing, cutting, gluing, and attaching system that guarantees a stable output of 8 pieces per minute — not only in testing, but in real factory production.
With a consistent 8 pcs/min operating speed, reaching up to 2,800 pieces per shift, the system replaces four manual stations with just one operator, significantly reducing labor costs while delivering perfectly uniform quality across every shift
Description
Automatic Bead Sewing and Attaching Machine-Guarantee a long-term stable output of 8 pcs/min
What Is a Bead Sewing and Attaching Machine?
Bead/Profile Tape Attached to the Snap Band
A bead sewing and attaching machine is a specialized system designed for integrated bead/profile tape sewing, cutting, gluing, and attaching during filter bag cuff processing. By automating these previously manual steps, the system ensures consistent alignment, stable tension, precise adhesive dosing, and reliable bonding strength—producing uniform, high-quality beads across all shifts and significantly improving overall filter bag production efficiency.
👉 Because this process is critical to both sealing performance and production capacity, automation quality varies greatly among manufacturers.
🌍 World’s First, Proven Through Years of Engineering Advancement
KABORY is the first manufacturer worldwide to successfully R&D and mass-produce a automated bead/profile tape sewing, cutting, gluing, and attaching line for filter bag cuffs.
After years of engineering refinement and continuous multi-shift field validation, we remain the only company able to guarantee a long-term stable output of 8 pcs/min, delivering up to 2,800 snap bands per shift with consistent alignment, bonding strength, and process reliability.
Such sustained performance is unattainable for low-cost competitors, whose speed, tension control, and seam accuracy typically fluctuate during continuous operation—creating serious constraints for high-volume filter bag production.
How the Bead Sewing and Attaching Machine Improves Filter Bag Production
Traditional bead/profile tape processing depends on manual sewing, manual cutting, manual taping, and manual attaching. This four-station workflow requires 6–7 operators, consumes large floor space, and produces inconsistent bead positioning, unstable tension, and frequent rework.
The Automatic Bead Sewing & Attaching Machine replaces these labor-intensive steps with a single automated workflow, ensuring continuous, high-precision processing.
Servo-controlled feeding and synchronized sewing maintain consistent stitch quality and accurate alignment. The automated gluing module delivers precise adhesive volume, eliminating over-gluing and under-gluing. Digital control minimizes operator influence, ensuring repeatable bead dimensions and bonding strength across all shifts.
This level of automation fundamentally optimizes traditional labor-heavy workflows and enables factories to scale production without adding manpower or expanding floor space.
Automated Workflow of the Bead Sewing and Attaching Machine
- 🔢Bead/Profile Tape Fully Automatic Sewing with Chain Stitch
- 🔢 Bead/Profile Tape Automatic Fixed-Length Cutting
- 🔢 Snap Band Placement (manual)
- 🔢 Automatic Bead Attaching to the Snap Band
- 🔢Tension-Controlled Loop Accumulator Between Sewing and Gluing
To ensure continuous and stable production, the machine is equipped with a tension-controlled loop accumulator positioned between the sewing unit and the gluing module.This accumulator temporarily stores a controlled length of bead/profile tape, allowing the
Loop Accumulator system to buffer natural speed variations between the two processes.
By stabilizing tension and decoupling the sewing speed from the gluing speed, the
accumulator prevents tape stretching, deformation, or sudden pulling—issues that are common in manual or semi-automatic operations.
As a result, the tape maintains perfect alignment and consistent tension
before entering the gluing module, ensuring accurate adhesive application and reliable bonding strength.
This design enables the entire sewing–gluing–attaching sequence to run smoothly and continuously, supporting multi-shift industrial production without interruption.

Industry Background and the Need for an Automated Bead Sewing and Attaching Machine
In today’s filter bag manufacturing industry, higher output, tighter quality requirements, and rising labor costs are driving factories to upgrade from manual bead/profile tape processing to automated systems.
Traditional multi-operator workflows can no longer meet modern production demands—they require large manpower, deliver inconsistent alignment and tension control, and limit overall throughput.
This is why many manufacturers are transitioning to automated solutions such as the bead sewing and attaching machine, which provides stable long-term productivity, traceable quality, and scalable output without increasing labor or floor space.
