The D.I. Rotary Pleater With Side Lock is designed and manufactured for simultaneous pleating and side seam locking of filter media used in automotive, hydraulic, oil, fuel, air, and industrial filtration products. Combining precision rotary pleating technology with an integrated side lock mechanism, the machine produces accurately pleated filter elements with secure side joints, improving filter strength and simplifying downstream assembly. Built with a heavy-duty fabricated steel frame, precision rotary pleating rollers, centralized lubrication system, air-cooled operation, and optional PLC-based automation, the machine delivers stable performance, high production efficiency, and long service life. Suitable for processing cellulose filter paper, synthetic filter media, glass fiber media, and specialty filtration materials, the D.I. Rotary Pleater With Side Lock integrates seamlessly with slitting machines, impregnation plants, curing systems, filter assembly equipment, and complete turnkey filter manufacturing lines. The machine can be fully customized according to pleat depth, pleat pitch, media width, side lock configuration, production speed, and customer-specific manufacturing requirements.
