Automatic Zig-Zag Rotary Air Filter Paper Pleating Machine
Industrial-grade automatic zig-zag rotary paper pleating machine designed for high-speed air filter production. Features a high-torque Mitsubishi/Delta servo system, adjustable pre-heating unit (up to 200°C), and intelligent PLC control with HMI. Ideal for automotive engine, cabin, and heavy-duty air filter media pleating with uniform geometry and micro-level tolerances.
This industrial Zig-Zag Rotary Paper Pleating Machine is engineered for high-speed, high-precision folding of filter media, specifically designed for manufacturing premium automotive air filters, cabin filters, and oil filter cartridges.
The mechanical process integrates structural pleat-marking and rotary rollers to guarantee uniform pleat geometry, tight tolerances, and exceptional production output. It is the ideal high-volume solution for professional air filter manufacturers looking to lower labor costs while maintaining strict quality control.
Technical Specifications
To ensure this machinery meets your precise workshop requirements, we provide fully customizable electrical and mechanical configurations:
Powered by premium Japanese Mitsubishi/Delta servo motor systems, the rotary pleat-forming rollers ensure consistent, high-speed zig-zag folds with micro-level repeatability. This eliminates the “pleat drift” common in older mechanical-linkage folder systems.
2. Intelligent HMI & Multi-Recipe Storage
The user-friendly touchscreen HMI allows real-time adjustments of pleat height, pleat spacing, roll tension, and total pleat count. Operators can save up to 50 distinct filter product recipes for quick changeovers, minimizing downtime.
3. Integrated Pre-Heating & Tension Control
To prevent filter paper fiber breakage during high-speed rolling, our machine incorporates an adjustable digital pre-heating plate (up to 200°C) and an automatic pneumatic tension controller. This keeps the media flat and consistently tensioned throughout the process.
4. Precision Hardened Alloy Pleating Rollers
The rotary rollers are CNC-ground from premium hardened tool steel and finished with a special wear-resistant coating. This ensures thousands of hours of continuous operation without deformation, even when pleating abrasive glass fiber media.
Applications & Industrial Uses
This high-speed zig-zag rotary pleater is widely deployed in assembly lines producing:
Automotive Engine Filters: Round, conical, and panel air filter elements.
Cabin Air Filters: Pleated synthetic media for passenger vehicle HVAC systems.
HVAC Panel Filters: Residential and commercial pleated air purification filters.

Frequently Asked Questions
A: Depending on the thickness of your cellulose or synthetic filter media, the machine runs stably at 15 to 40 meters per minute, which is significantly faster than traditional blade/knife pleaters.
A: The pleat height of a rotary pleater is determined by the roller diameter and geometry. To adjust the pleat height significantly, the rotary rollers need to be swapped. We can customize extra sets of rollers according to your filter specifications.
A: Pre-heating softens the resins within cellulose and synthetic fibers, allowing them to form permanent zig-zag pleats without breaking or cracking the media structure under high speeds.
A: Yes. We configure the motor and heating coil systems to support your country’s power grid, such as 380V 50Hz, 220V 60Hz (3-Phase), or 415V 50Hz.
