When you're running paper at nearly 200 m/min, cutting speed is not the only thing that matters.
The paper still needs to stay in position. The cut needs to be clean. The sheets need to come out square. And most importantly, the machine needs to keep doing the same job roll after roll without constant adjustment.
That's where the CHM-SGT1400H High Precision Twin Rotary Knife Sheeter is built to make a difference.
A Real Production Job, Not Just a Machine Specification
One recent customer application gives a good example of what the CHM-SGT1400H is designed for.
The customer is running 150gsm printed paper, producing sheets at 1245 × 582 mm.
During production, the machine is running at around 198 m/min, with the knife speed reaching approximately 340 cuts/min. The job also requires printed-mark cutting and trimming on both sides.
These are actual production requirements from a customer project.
For us, this tells much more about a paper sheeter than simply saying "high speed" or "high precision."
Because the real question is:
Can the machine keep the cut clean and stable when the paper is actually running?
That's what matters on the production floor.
Why Use a Twin Rotary Knife?
The cutting method is one of the key differences between the SGT series and a conventional single rotary knife sheeter.
The CHM-SGT1400H uses an upper and lower rotary knife system. Both knives rotate during the cutting process, with the cutting action synchronised with the movement of the paper.
As the paper speed increases, keeping this timing under control becomes increasingly important.
A well-synchronised cutting system helps reduce disturbance to the paper during cutting and supports a cleaner cutting edge and more consistent sheet size.
For converters, the benefit is simple:
Less attention to the cutting process. More consistent sheets coming off the machine.
What Does That Mean for the Finished Sheet?
A machine can look impressive when it is running empty.
But that's not how customers judge a sheeter.
They look at the finished sheets.
Are the four sides clean?
Are the sheets square?
Does the stack stay neat?
Does the paper move smoothly into the next process?
These are the details that eventually affect production.
For printed paper, coated paper, kraft paper, board and other demanding materials, cutting quality becomes even more important. A small problem at the sheeting stage can become a bigger problem during printing, packaging or finishing.
The CHM-SGT1400H Twin Knife Sheeter is designed with this in mind — keeping the paper under control while maintaining accurate, stable cutting throughout production.
Built for More Than One Type of Paper
The SGT series is not designed around one single paper application.
Depending on the configuration, the CHM-SGT1400/1700 High Precision Twin Rotary Knife Roll Paper Sheeter can be used for materials such as:
Coated paper
Kraft paper
Cultural paper
Art paper
Whiteboard
Printed paper
Other paper and board materials
This makes the machine suitable for different paper converting requirements, especially where cutting quality and production stability are important.
Of course, not every customer needs a twin-knife sheeter.
For lighter materials and more general sheeting applications, a single rotary knife machine can already provide the performance required.
The right choice should always start with the paper and the finished product — not simply with the machine model.
What Should You Consider Before Choosing a Paper Sheeter?
Before choosing a Paper Sheeter Machine or Roll To Sheet Cutting Machine, there are a few basic questions that need to be answered:
What is the paper GSM?
What are the roll width and diameter?
What sheet size do you need?
What production speed are you targeting?
How many rolls need to be processed?
What will the finished sheets be used for?
These details affect the machine configuration.
For example, a customer producing standard copy paper has very different requirements from a printer running large-format printed paper. A packaging converter working with heavier board will have another set of requirements altogether.
There is no "one machine fits everything" answer.
The better approach is to match the sheeter to the actual production job.
From Roll to Sheet — Every Section Has a Job
A roll-to-sheet process may look straightforward:
Paper Roll → Feeding → Web Guiding → Cutting → Conveying → Finished Sheet
But stable production depends on every section working properly together.
The unwind system needs to feed the roll smoothly.
The web guide keeps the paper correctly positioned.
The cutting unit needs to stay synchronised with the paper movement.
The conveyor then delivers the finished sheets consistently for stacking or the next process.
That's why a high-speed paper sheeter is not just about the knife.
The whole machine has to work as one system.
The CHM-SGT1400H includes key sections such as the unwind stand, web guide system, cutting and slitting section, electrical system and conveyor unit, all working together to keep the paper under control from roll to finished sheet.
The Right Machine Starts With the Right Application
At CHM, we don't believe that every customer needs the biggest or most expensive machine.
A customer processing 80gsm paper should not necessarily use the same setup as a converter running 250gsm board.
The machine should match the job.
That's why we look at the actual production requirements before recommending a configuration.
Paper GSM.
Roll specification.
Sheet size.
Target speed.
Cutting requirements.
Final application.
Once these are clear, it becomes much easier to decide whether a single rotary knife sheeter or a twin rotary knife sheeter is the better fit.
See What Your Paper Can Do
The CHM-SGT1400H is built for customers who need more than simply fast cutting.
It is for production where clean edges, accurate sheet size, stable running and consistent output all matter.
And while specifications can tell you what a machine is designed to do, the most useful test is much simpler:
Put your own paper through the machine.
If you're considering a CHM-SGT1400H Twin Knife Sheeter or another high precision Paper Sheeter Machine, send us your paper GSM, roll specifications, finished sheet size and target speed.
We'll look at your actual application and help you find the sheeting solution that fits your production.
