Nine Dragons Paper Upgrades U.S. Copy Paper Production Line with CHM High-Speed A4 Paper Machines

Introduction:

Nine Dragons Paper, one of the world’s largest paper manufacturers, recently completed a major upgrade of its copy paper production line in the United States. The project was supported by CHM, a leading manufacturer of paper roll to sheets cutting machines and A4 copy paper production lines. Through advanced engineering, customized design, and precise installation, CHM successfully delivered two high‑performance machines that significantly improve production efficiency and product quality for the North American market.

Understanding the Upgrade Requirements

When Nine Dragons Paper initiated its production line upgrade project, the CHM sales and engineering teams immediately became involved in the early consultation stage. The goal was to fully understand the customer’s production objectives, technical requirements, and investment budget.

The primary objectives of the project included:

- Increasing copy paper production efficiency

- Supporting both international A4 size and North American Letter size formats

- Improving cutting precision for thick paper rolls

- Reducing labor involvement in stacking and packaging

After detailed technical discussions and a year-long development process, CHM designed a new generation machine configuration specifically tailored to the needs of Nine

Dragons Paper. Through an open international bidding process, CHM successfully won the order and completed the installation and commissioning of two advanced machines.

High-Speed A4 Copy Paper Production Line

The first machine delivered in this project is a fully automatic high-speed A4 copy paper production line. This machine is designed to process paper rolls and convert them into finished copy paper reams ready for packaging and distribution.

A key feature of this production line is its ability to produce both A4 copy paper and North American Letter size paper without any mechanical modification to the cutting system.

Instead of replacing cutting knife structures, operators can simply change the cutting parameters on the machine’s control interface. With a few adjustments on the touchscreen control panel, the production line can switch between the two formats instantly.

This capability is particularly important for Nine Dragons Paper’s U.S. manufacturing facility, which primarily serves the North American office paper market where Letter size copy paper demand remains extremely strong.

By combining flexibility and high productivity, the new CHM A4 copy paper production line enables Nine Dragons Paper to respond quickly to market demand while maintaining high production efficiency.

Six-Roll Double Rotary Sheeting Machine

The second machine delivered in this upgrade project highlights CHM’s core technology in paper roll sheeting machines.

This high-speed double rotary sheeter is equipped with three unwinding stands, allowing the machine to process up to six paper rolls simultaneously. This multi-roll configuration significantly increases production capacity compared with traditional single-roll cutting machines.

 The machine adopts a double spiral rotary cutting system. This advanced cutting structure provides several key advantages:

- Higher cutting accuracy when processing thick paper rolls

- Clean cutting edges without paper dust or burrs

- Stable performance at high production speeds

 The finished sheets produced by this machine can be directly transferred to printing machines for applications such as:

- Instruction manuals

- Newspapers

- Magazines

- Commercial printed materials

Another innovative feature of the system is the high-speed automatic stacking unit. The stacking module is designed with a non-stop pallet exchange function. Once a pallet is fully stacked, the automatic conveying system immediately transports it to the packaging station.

Meanwhile, operators do not need to slow down the machine during pallet replacement, ensuring continuous production and maximizing operational efficiency.

CHM’s 23 Years of Paper Converting Technology

CHM has always focused on the research and development of roll paper cutting machines and paper converting equipment. As the first manufacturer in China to develop A4 copy paper production lines, CHM has accumulated more than 23 years of experience in this specialized field.

Today, CHM machines are widely used by paper mills and paper converters around the world. The company continues to provide reliable equipment, advanced technology, and professional after-sales service to support the growing global paper industry.

With the successful completion of the Nine Dragons Paper upgrade project, CHM once again demonstrates its technical strength in high-speed paper roll to sheets cutting machines and copy paper production solutions.

Conclusion

The modernization of Nine Dragons Paper’s U.S. production line represents a significant step toward higher productivity and greater flexibility in the office paper market. With CHM’s high-speed A4 copy paper production line and six-roll double rotary sheeting machine, the factory is now equipped to efficiently meet the strong demand for both A4 and Letter size copy paper.

For paper mills and paper converters seeking reliable paper roll to sheets cutting machines, CHM continues to be a trusted technology partner delivering performance, precision, and long-term value.
