Rotary Pleating Systems for Heavy & Panel Air Filters

Achieving high-speed production for automotive and heavy-duty industrial filters requires specialized folding configurations. Our product range features the air filter zig-zag rotary paper pleating machine, panel air filter rotary pleating paper machine, and rotary pleating machine for heavy air filters. Utilizing custom-engineered rollers and integrated servo drives, these systems form stable, uniform zig-zag or flat pleats in filter paper, maintaining structured flow paths for demanding heavy equipment and panel filter applications.

CNC Knife Pleating Technology for Versatile Media

For filtration manufacturers processing diverse raw materials, flexibility in pleat depth and spacing is essential. We manufacture the advanced CNC knife pleating machine for air filter media, standard knife pleating machines for air filter paper, and our strengthened knife pleating machine for heavier filter media. By utilizing a computer-controlled strengthening blade and heavy-duty frame structure, these machines easily crease synthetic fibers, non-woven fabrics, and multi-layer composites with minimal maintenance.

Specialized Glass Fiber Pleating & Gluing Integration

Processing delicate fiberglass materials requires careful handling to prevent fiber breakage during folding. Our filter pleating and gluing machine for glass fiber material integrates automated hot-melt bead dispensing directly into the pleating cycle. This combined system ensures that individual pleats are spaced correctly and bonded securely, stabilizing the fiberglass media before it is framed and sealed, which increases production speed and final cartridge stability.

Frequently Asked Questions

Common questions about our products and ordering process.

Rotary pleating machines use pre-designed metal rollers to crease filter paper rapidly, ideal for high-speed, single-size production like automotive cabin or panel air filters. Knife pleating machines use a moving blade to fold media, offering higher flexibility for adjusting pleat heights and handling thicker, multi-layer materials via CNC controls.

Yes. Our strengthened knife pleating machine features a reinforced supporting frame and a high-durability blade. This robust design allows it to crease heavier materials, including wire-mesh backed filter media and thick synthetic composites, without compromising machine alignment.

The gluing module is synchronized with the mechanical pleating cycle. It dispenses precise hot-melt adhesive beads onto the moving glass fiber media, maintaining even pleat spacing and structural stability before the media goes into the assembly stage.
