Choosing the right A4 paper production line is critical for paper converting factories. Production capacity, paper width, factory layout, and automation requirements all influence machine selection.
The CHM A4-4 and A4-5 production lines are both designed for automatic A4 copy paper manufacturing, but they serve different production needs.
Main Difference Between A4-4 and A4-5
The biggest differences include:
Paper width
Cutting lanes
Production output
Machine dimensions
Power configuration
The A4-5 model supports wider paper rolls and higher production capacity.
Production Capacity Comparison
CHM A4-4
Output: 30–37 reams per minute
Main power: 32 kW
Suitable for medium-volume production
CHM A4-5
Output: 42 reams per minute
Main power: 34 kW
Suitable for high-volume production
For factories requiring maximum productivity, A4-5 provides stronger capacity advantages.
Machine Size Comparison
A4-4 Dimensions
17681 × 4140 × 3190 mm
A4-5 Dimensions
20114 × 4355 × 3190 mm
Factories with limited workshop space may prefer the more compact A4-4 model.
Automation Configuration
Both models support:
Automatic unwinding
Web guiding
Slitting
Cross cutting
Automatic stacking
Ream wrapping
Carton packing
Robotic palletizing
The fully automatic closed-loop system reduces manual operation and improves production stability.
Which Machine Should You Choose?
Choose A4-4 If:
You have limited factory space
You run medium production volumes
You require stable and flexible production
You have lower initial investment requirements
Choose A4-5 If:
You need maximum production output
You process wider paper rolls
You focus on large-scale copy paper manufacturing
You require high-speed continuous operation
Conclusion
Both A4-4 and A4-5 production lines provide advanced automation and high cutting precision. The final choice depends on production goals, factory conditions, and expected output.
For high-capacity factories, A4-5 delivers stronger productivity. For balanced production and flexible operation, A4-4 remains an excellent solution.
In Japan’s paper converting industry, expectations are different. Speed matters – but precision, consistency, and stability matter even more.
A Japanese paper processor recently upgraded with the 1400J paper sheeter from SMH, aiming to improve cutting accuracy and long-run stability for high-quality paper products.
The Challenge: Precision at Scale
The factory runs lightweight coated paper and high-grade printing materials. Their main problems were:
Slight deviation in sheet squareness at higher speeds
Inconsistent cutting length over long runs
Sensitivity to tension and humidity
At lower speeds, these issues were manageable. But as production demand grew, maintaining both speed and precision became difficult.
Why This Is Difficult
Lightweight and coated papers react strongly to tension fluctuation, static electricity, and tiny alignment errors. Even small variations cause visible edge defects, stacking inconsistency, and lower yield in downstream printing. For Japanese customers, these tolerances are not acceptable.
How the 1400J Solved It
The 1400J was configured with:
Servo-driven cutting system – consistent length accuracy
Optimized frame rigidity – minimal vibration at high speed
Integrated tension control – stable web handling
Precision alignment system – better sheet squareness
More importantly, it maintains performance over long runs – not just at startup.
Measurable Results
After installation:
Cutting consistency improved significantly
Production speed increased without quality loss
Defect rate reduced
Operator intervention decreased
The factory reported a more stable and predictable process, especially for high-grade paper orders.
A Standard, Not Just an Upgrade
In markets like Japan, equipment is judged by real production performance – not just specs. The 1400J delivers stable operation, repeatable accuracy, and adaptability to different paper grades.
