Paper converters and office supply manufacturers face a constant challenge: producing consistent reams of A4 copy paper at high speed without wasting material. Hand-fed guillotines simply can’t keep up with modern demand. Every ream must be perfectly cut, counted, and stacked—and mistakes cost money. That’s why we built the automatic A4 paper cutting machine.
It takes jumbo rolls, unwinds them, cuts precise A4 sheets, counts them into 500-page reams, and stacks them automatically—all in one continuous line. One operator runs the entire system, replacing a crew of cutters and counters. Output soars. Labor costs drop.
At YG Machinery, we’ve been building paper converting equipment for over a decade. Our factory in Zhengzhou produces this A4 cutting line with 45kW total power. Every machine is fully tested before shipping, and we provide each buyer with a test report and video of their unit in operation.

How an A4 Cutting Machine Transforms Production
An A4 cutting machine operates as an integrated system. The jumbo roll sits on an unwind stand. Paper feeds through tension controls, trim slitters, and a cutting section. Then it moves to a stacking and ream counting station. The entire process is continuous.
Here is what the machine does for your production line:
- Runs at 0-150 m/min, adjustable for different paper grades
- Cuts 4 sheets simultaneously – each cut length is exactly 297mm
- Counts 500 sheets per ream automatically via PLC control
- Trims both edges – remove up to 10mm or as little as 3mm each side
- Stacks reams to 65mm height – that is 500 sheets of 80gsm paper
- Accommodates 3″ or 6″ paper cores without changeover
The rheological frequency speed control lets operators adjust speed on the fly. For lightweight 60gsm paper, run faster. For 100gsm or multi-layer loads, slow down. The system maintains cutting precision across the full speed range.

A4 Size Paper Cutting Machine: Precision You Can Count On
An A4 size paper cutting machine must deliver consistent precision. Copy paper buyers reject reams with uneven edges or incorrect sizes. The YG machine uses several design features to ensure accuracy.
Cross-cutting accuracy. The rotary knife system uses precise gearing. The knife speed synchronizes with paper feed speed. Each cut is exactly 297mm. No drifting. No accumulation of errors.
Trim control. Trimming sections remove edge irregularities before cutting. The machine trims 3- 10 mm from each side. This ensures every sheet has clean, square edges. No dog-eared corners. No wavy edges.
Tension control. The paper feed system maintains constant tension. Variations in tension cause uneven cutting. The YG system adjusts automatically as the roll diameter decreases.
Stacking precision. The stacking section collects cut sheets into neat piles. The ream height is controlled to 65mm maximum. Taller stacks would cause the top sheets to slide. The PLC monitors height and triggers automatic discharge when the ream is complete.
The machine cuts to ±0.2mm accuracy. This matches or exceeds the specifications of major office paper brands. Your customers will not notice any difference between your reams and the market leaders.

What an A4 Paper Cutter Machine Price Includes
The A4 paper cutter machine price from YG covers a complete production line. You get more than just the cutting section. The package includes everything needed to start production.
Unwind stand. The stand handles 3″ or 6″ cores. It includes brakes to control unwinding tension. The lift system uses hydraulic cylinders to raise rolls into position.
Tension control section. The system maintains consistent paper tension as the roll diameter changes. This prevents wrinkles and stretching.
Trimming and slitting section. Trimming knives clean the edges. Slitting knives separate the web into multiple streams for multi-up cutting.
Cross-cutting section. The rotary knife cuts sheets to length. The precision gearing ensures accurate cuts at all speeds.
Stacking and counting section. Sheets stack automatically. The PLC counts sheets and discharges full reams. A conveyor moves reams to the packaging area.
Control system. The PLC controls all functions. The touchscreen display shows production data, fault codes, and adjustment settings. The 24V DC control circuit improves safety for operators.
YG Machinery provides installation support and operator training. The training covers setup, operation, daily maintenance, and fault-finding.
A Real-World Case of A4 Cutting Machine: Indonesian Mill Cuts Costs by 40%
A paper mill in Surabaya, Indonesia, installed a YG automatic A4 paper cutting machine in early 2022. Before the installation, they relied on three separate guillotine cutters with a crew of 12 people per shift. Each shift produced 4,500 reams. Reject rates ran at 3-4% due to cutting errors, miscounts, and inconsistent ream heights. The mill lost about 180 reams per shift to waste. That added up to over 65,000 reams of lost production annually.
The mill installed the YG line in a 400 square meter area. The installation took 12 days, including operator training. The machine runs with just 3 operators per shift. Production jumped to 8,000 reams per shift – a 78% increase. The reject rate dropped to 0.5%. The mill now produces consistent 500-sheet reams with precise 210×297mm dimensions every time. The ream height stays within ±1mm of the target.
The CFO calculated the savings. Labor costs dropped from 12 workers to 3 per shift – a 75% reduction. Material waste dropped from 4% to 0.5% – saving over 60,000 reams of paper annually. Total annual savings exceeded $180,000. The machine paid for itself in 10 months. The mill now runs two shifts and has eliminated overtime payments. They are planning to add a second line next year.
6 FAQs About Automatic A4 Paper Cutting Machine
The machine handles 60-100g/m² paper. This covers standard copy paper, lightweight offset paper, and heavier bond paper. For paper outside this range, YG offers customized settings.
The full line needs 3 operators per shift. One manages the unwind and tension control. One monitors the cutting section. One handles ream discharge and packaging. For automatic packaging integration, reduce to 2 operators.
For 80gsm paper, 500 sheets stack to approximately 50-52mm. The maximum ream height is 65mm. The touchscreen lets you adjust the count if you need fewer sheets per ream.
Yes. The cutting length is 297mm, which is the A4 long side. For A3, you run the paper with the short side as the width, and cut two A4 sheets per A3 parent sheet. The machine handles both formats.
The total line length is approximately 20-25 meters, including the unwind stand, cutting section, and stacking area. Width is about 3 meters. Allow additional space for roll storage and ream packing. YG provides a layout drawing before installation.
The unwind stand accepts rolls up to 1200mm diameter. The core sizes are 3″ (76.2mm) and 6″ (152.4mm). For larger rolls, YG offers custom modifications to the unwind stand.
