What Is a Modular Filter Paper Pleating & Gluing Line?
A modular filter production line is a set of independent but fully synchronized machines designed for filter paper forming.
Our system includes three professional units:
Pre‑slitting & paper feeding unit
Servo air filter pleating equipment
Automatic hot‑melt gluing machine
This structure ensures high stability, easy maintenance, and strong flexibility for industrial and automotive filter manufacturing.
Core Technical Knowledge You Need to Know
1. Why Servo Control Is Important for Pleating?
Servo motors provide closed‑loop precision control for pleating blades.
✔ Stable pleat height and spacing
✔ High speed up to 280 folds/min
✔ Wide adjustment range: 5–70mm
✔ Less wear, longer service life
2. Why Heat Setting Is Necessary?
Heat setting eliminates internal stress of filter paper after folding.
✔ Temperature range: room temperature ~ 260°C
✔ Prevents pleat rebound and deformation
✔ Improves glue adhesion and stability
✔ Ensures filters keep shape in high‑temperature environments
3. Why Synchronized Control Matters?
All three units run at matched speed via PLC and infrared monitoring.
✔ No paper stretching or wrinkling
✔ Accurate alignment between pleating and gluing
✔ Higher product consistency
✔ Lower defect rate
4. Advantages of Modular Design
✔ Easier maintenance and repair
✔ Flexible upgrade for new products
✔ Stable performance for each process
✔ Lower risk of full‑line shutdown
✔ Longer lifespan for core components
