Corrugated Paper Machine for Containerboard Mills
The corrugated paper machine is the core of any modern containerboard mill, combining high-speed operation with exceptional sheet strength and uniformity. This corrugated paper machine utilizes a long fourdrinier wire section with multiple dewatering elements, allowing rapid water removal while maintaining good formation. The press section of this corrugated paper machine employs two vacuum suction transfer rolls and two large-diameter blind drilled press rolls, achieving high dryness without crushing the sheet.
A key advantage of this corrugated paper machine is the integration of vacuum cylinders in the pre-drying and post-drying sections, which enhance heat transfer and significantly reduce steam consumption. The corrugated paper machine also includes an inclined surface sizing machine with adjustable loading pressure, applying starch to both sides for improved strength properties. A reel-drum type winder with semi-automatic roll changing ensures efficient finishing of parent rolls. With a user-friendly design featuring hydraulic loading, electric tensioning devices, and a cordless tail threading system, this corrugated paper machine minimizes downtime and maximizes output for mills producing fluting, test liner, and kraft liner.
