Pulan's Full-Auto Panel Air Filter Paper Pleating Production Line is engineered for the continuous pleating and hot melt gluing of filter media used in automotive PU panel air filters. The production line combines paper feeding, steam humidification, pleating, adhesive application, automatic counting, and product conveying into a single integrated system, eliminating the need for multiple standalone machines. It accommodates filter media widths from 90–350mm, pleat heights of 16–70mm, and operates at an adjustable production speed of 5–30m/min. Precision embossing rollers ensure uniform pleats with smooth, consistent end faces.
The Full-Auto Panel Air Filter Paper Pleating Production Line is a fully automatic manufacturing system developed for producing pleated filter media for automotive PU air filters. It consists of a paper unwinding stand, steam humidification unit, pleating machine, hot melt gluing system, automatic counter, discharge conveyor, and PLC control system.
During production, the filter media first passes through the steam unit to improve flexibility before entering the embossing rollers, where crease lines are accurately formed. Hot melt adhesive is then applied through precision glue nozzles, after which the media is folded by the pleating rollers. Finally, the pleated filter paper is dried, stabilized with airflow, and conveyed to the next production stage. The entire process ensures stable pleat geometry and consistent product quality during continuous mass production.
The production line performs pleating and adhesive application in one continuous operation. After humidification, the filter media passes through the embossing rollers to create uniform crease lines. Hot melt adhesive is then applied before the media enters the pleating rollers, where the final pleat shape is formed. Airflow from the drying fan helps stabilize the pleats before the finished material is discharged by the conveyor.

Q1: Why does the embossing position shift during operation?
A: Misalignment is usually caused by the upper and lower embossing rollers not being parallel. If the paper drifts to the left, rotate the right adjustment bolt clockwise (or the left bolt counterclockwise) to lower the right side of the upper roller. Reverse the adjustment if the paper drifts to the right.
Q2: What causes uneven pleat formation?
A: First, check whether the embossing rollers are producing uniform crease lines. If the embossing is correct, adjust the clearance between the upper and lower pleating rollers using the adjustment handwheel or adjusting nut until the gap is even.
Q3: Why do the pleats separate after gluing?
A: This is generally caused by either insufficient adhesive application or excessive airflow that cures the adhesive too quickly. Increase the glue volume or reduce the fan airflow accordingly.
Q4: What should I do if the paper does not feed properly or the machine fails to stop automatically?
A: Check whether the photoelectric sensor is blocked or damaged. Replace the sensor or its control board if necessary. If the problem remains, inspect the transmission system for mechanical faults.
The Full-Auto Panel Air Filter Paper Pleating Production Line is designed for continuous, high-volume production of automotive PU panel air filter media. Pulan provides free sample testing—customers can send filter media for trial production before placing an order.
Custom configurations are available for wider media, special pleat height requirements, or alternative heating methods. Every production line is supplied with Chinese and English operating manuals, electrical schematics, and pneumatic component documentation.
