Knife Pleating Machine for Air Filter Paper

This classic Knife Pleating Machine is designed for the precision folding of air filter paper, cellulose media, and standard synthetic non-woven rolls. Employing a reliable mechanical reciprocating knife mechanism combined with a pneumatic material feed, this system delivers exceptionally uniform pleats, maximizing the effective surface area and air throughput of your finished filter elements.

As an economical and highly stable production workhorse, this machine is preferred by small-to-medium-scale factories requiring continuous, trouble-free running. Its simple, robust design ensures low maintenance costs while achieving the strict structural tolerances required by standard HVAC and automotive air filtration applications.

Technical Specifications

To ensure the machine matches your factory’s electrical and technical requirements, the standard parameters are detailed below:

Key Features & Mechanical Advantages

1. Proven Reciprocating Knife Mechanism

The mechanical folding knives are precisely calibrated to press, mark, and crease the filter paper evenly. This stable physical action guarantees straight, parallel pleats across entire production batches, ensuring consistent quality and structural rigidity.

2. Adjustable Pleat Spacing and Height

Operators can easily adjust both the pleat height (within the 12–30 mm limit) and pleat pitch to produce filter packs for a wide range of custom specifications, reducing the need for multiple standalone single-size folding units.

3. Stable Pneumatic Feed & Tension Control

Operating at a standard 0.6 MPa working pressure, the pneumatic feed system advances the media roll smoothly and continuously. This controlled tension eliminates slip and prevents physical distortion or tearing of delicate cellulose paper fibers.

4. User-Friendly Touchscreen HMI

The control console features a highly responsive HMI screen that simplifies initial machine setup, allows real-time production monitoring, and reduces operation errors, ensuring that even general workshop staff can operate it with minimal training.

5. Heavy-Duty Industrial Construction

The machine is built upon a rigid steel alloy structural frame to minimize operational vibrations during high-speed folding cycles, ensuring thousands of hours of reliable, continuous production with minimum wear.

Applications & Industrial Uses

This standard mechanical knife pleating machine is widely deployed in production lines for:

• Automotive Climate & Engine Filters: Creasing standard filter paper for vehicle engine air intake and cabin air filtration systems.
• Commercial HVAC Systems: Pleating media for office and industrial air handling unit (AHU) panel filters.
• High-Efficiency Filtration Components: Creating high-density pleated inserts for standard technical air purification elements.

Note: If your production requires inline hot-melt glue bead application specifically on delicate glass fiber materials, please refer to our Automatic Glass Fiber Filter Pleating & Gluing Machine.
