CHM Double Rotary Sheeter Installed at Nine Dragons Paper USA for High-Speed Paper Converting Production

Introduction

In modern paper converting production, paper mills and converters require stable and accurate sheeting equipment to process different paper grades under continuous production conditions.

With increasing requirements for sheet quality, production efficiency, and process consistency, Paper Sheeter Machine technology plays an important role in paper roll-to-sheet converting applications.

CHM Machinery recently completed the installation and commissioning of the CHM-SGT1400H/1700H High Precision Double Rotary Sheeter at Nine Dragons Paper USA.

The machine has been put into production for paper sheeting applications, providing stable cutting performance for high-speed paper converting processes.

Production Requirements for Modern Paper Converting

For large-scale paper production, sheeting equipment needs to maintain consistent cutting accuracy during long-time operation.

Modern paper converters mainly focus on accurate sheet size control, stable cutting quality, reliable high-speed operation, and flexible processing capability for different paper materials.

For coated paper, packaging paper, and specialty paper applications, cutting performance directly affects the following printing and converting processes.

A Paper Roll To Sheet Cutting Machine requires stable tension control, precise knife synchronization, and reliable automation systems to maintain production consistency.

CHM-SGT1400H/1700H Production Performance

During production at Nine Dragons Paper USA, the CHM-SGT1400H/1700H was used for processing 70gsm PENNACOOK OFFSET paper.

The machine reached a production speed of up to 200m/min, with a maximum cutting speed of 300m/min and cutting frequency of up to 271 cuts/min.

The equipment also supports multiple roll cutting capability for continuous paper converting production.

The machine structure allows stable roll-to-sheet production while maintaining consistent sheet output.

Double Rotary Sheeter Cutting Technology

The cutting system is the core part of a Paper Sheeter Machine.

The Double Rotary Sheeter uses synchronized top and bottom rotary knives to cut the moving paper web continuously.

Compared with traditional cutting methods, the rotary cutting structure provides smoother cutting movement and reduces mechanical impact during operation.

The synchronized upper and lower knives improve cutting stability by reducing vibration during the cutting process.

This helps maintain cleaner sheet edges and stable sheet dimensions during continuous production.

During high-speed operation, knife synchronization plays an important role in maintaining cutting accuracy.

The Double Rotary Sheeter system keeps knife movement matched with paper feeding speed, allowing stable production under high-speed working conditions.

The rotary cutting process also helps reduce rough cutting edges, paper deformation, excessive paper dust, and uneven sheet cutting.

This cutting method is suitable for applications requiring consistent sheet quality.

Application Range of CHM-SGT1400H/1700H

The CHM-SGT1400H/1700H is designed for different paper converting applications.

The machine can process paper materials from 150-1000gsm, including coated paper, kraft paper, white board, packaging paper, and specialty paper.

Different working widths are available with CHM-SGT1400H and CHM-SGT1700H models to match different production capacity requirements.

Automated Systems for Stable Production

The CHM-SGT1400H/1700H integrates multiple systems for production control and operation management.

The automatic tension control system maintains stable paper tension during production and helps reduce problems caused by paper stretching, wrinkles, and unstable feeding.

The Auto EPC (Edge Paper Control) system detects paper position changes during operation.

It helps maintain web alignment and reduces paper deviation, edge position variation, and feeding instability.

The machine uses a human-machine interface for parameter setting, production monitoring, and operation control.

Operators can manage production conditions through the control system.

The automatic positioning system supports efficient adjustment of key components, including unwind stand, correction system, and slitting knives.

This helps reduce setup time during production changes.

Complete Paper Roll To Sheet Production System

The CHM-SGT1400H/1700H integrates multiple production sections to complete the roll-to-sheet converting process.

The production system includes hydraulic unwind stand, automatic tension control system, slitting and waste edge collection system, high precision Double Rotary Sheeter cutting unit, conveyor system, automatic counting system, and jogger stacking system.

The complete production line covers the process from paper roll unwinding to finished sheet stacking.

Conclusion

The installation of the CHM-SGT1400H/1700H Double Rotary Sheeter at Nine Dragons Paper USA demonstrates the application of high-precision sheeting equipment in large-scale paper converting production.

Through synchronized rotary cutting technology, tension control, and automated production systems, the machine provides stable roll-to-sheet processing capability for different paper applications.

CHM Machinery continues to develop Paper Sheeter Machine solutions, including Double Rotary Sheeter, Single Rotary Sheeter, Paper Roll To Sheet Cutting Machine, and A4 Paper Sheeting Machine systems for paper mills and converters worldwide.
