Buying a toilet paper machine for an overseas factory is a major investment. Before the equipment is packed and shipped, buyers should conduct a systematic inspection to confirm that the machine matches the agreed configuration, operates correctly, produces the required toilet paper rolls, and includes all accessories and documents specified in the order.
A toilet paper machine inspection should not be limited to checking whether the machine can start. A proper pre-shipment inspection should cover the machine structure, electrical system, operating functions, production trial, finished-roll quality, safety devices, spare parts, documentation, and export packaging.
Factory acceptance testing is generally performed before shipment at the supplier's facility and should be based on agreed specifications and measurable acceptance criteria.
1. Check the Toilet Paper Machine Configuration
The first step is to compare the finished machine with the purchase order, quotation, technical specification, and approved configuration.
Check items such as:
| Inspection Item | What to Confirm |
|---|---|
| Machine model | Matches the ordered model |
| Working width | Matches the agreed specification |
| Number of plies | 1-ply, 2-ply, 3-ply, etc. |
| Finished roll diameter | Matches the required product range |
| Core diameter | Confirm the required core size |
| Jumbo roll specification | Width and diameter are compatible |
| Embossing system | Confirm selected pattern and configuration |
| Perforation system | Confirm perforation function and adjustment |
| Electrical voltage | Matches the destination country |
| Control system | PLC, touchscreen and control components |
| Optional equipment | Confirm every purchased option is installed |
This check is important because a machine can look almost identical to the model shown in a quotation while having different options or configurations.
For example, if a buyer orders a machine configured for a 300 mm finished roll diameter but the delivered machine is configured differently, the problem may not become obvious until production begins.
The approved technical specification should therefore be treated as the inspection baseline rather than relying only on photographs or a sales description.
2. Inspect the Main Mechanical Structure
After confirming the configuration, inspect the physical condition of the machine.
Check:
Main machine frame
Welding points
Bearings
Shafts
Rollers
Gears and transmission components
Paper-guiding components
Unwinding section
Embossing section
Perforation section
Rewinding section
Core-feeding components
Guards and covers
Fasteners and mounting points
There should be no obvious cracks, deformation, loose components, abnormal oil leakage, or damaged protective covers.
Pay particular attention to rotating components and paper-contact surfaces. Components should be properly installed and aligned, with no obvious interference during operation.
A pre-shipment inspection is most useful when the machine is still at the supplier's factory because mechanical corrections can normally be made before export packing and international transportation.
3. Run the Machine Without Material
An empty-machine test is a useful first functional check.
Start the machine without tissue paper and observe:
Motor operation
Transmission movement
Roller rotation
Unwinding movement
Embossing movement
Perforation mechanism
Core-feeding mechanism
Conveyor operation
Sensors
Control panel
Emergency stop
Abnormal vibration
Unusual noise
The purpose is not to prove the final production capacity. Instead, it helps identify mechanical or electrical problems before introducing paper.
If the machine produces abnormal vibration or noise during an empty run, the problem should be investigated before shipment.
4. Conduct a Real Paper Trial
A toilet paper making machine inspection should ideally include a trial using tissue paper that is reasonably close to the customer's intended production material.
The supplier and buyer should confirm the test material in advance, including factors such as:
Paper width
Basis weight
Number of plies
Jumbo roll diameter
Paper quality
Core specification
A machine trial using different paper from the customer's actual production material can produce misleading results.
For example, a rewinding machine may run smoothly with one tissue specification but require different tension or other settings when processing another paper grade.
Therefore, the trial record should clearly identify the material used during testing.
5. Check Finished Toilet Paper Roll Quality
This is one of the most important parts of the toilet paper machine before shipment inspection.
During the trial, collect finished rolls and check:
Roll Diameter
Measure several finished rolls rather than checking only one sample.
For example:
| Sample | Target Diameter | Measured Diameter |
|---|---|---|
| Roll 1 | 100 mm | 99.5 mm |
| Roll 2 | 100 mm | 100.2 mm |
| Roll 3 | 100 mm | 100.0 mm |
| Roll 4 | 100 mm | 99.8 mm |
| Roll 5 | 100 mm | 100.3 mm |
The actual acceptance range should be based on the agreed machine specification and finished-product requirements rather than a universal tolerance.
Paper Alignment
Check whether the paper layers remain properly aligned during rewinding.
Poor alignment can affect the appearance of finished rolls and may create problems for subsequent packaging.
Perforation
Check:
Perforation position
Perforation consistency
Tear performance
Sheet length
The finished roll should have consistent perforation under the agreed production conditions.
Embossing
Inspect:
Pattern clarity
Uniformity
Alignment
Pressure consistency
The embossing result should correspond to the agreed sample or specification.
Roll Density
Check whether the finished rolls have consistent hardness and winding quality.
A machine may produce the correct diameter while still producing rolls that are too loose or too tight.
Paper Log Formation
For a production line using log saw cutting, also check the paper log before cutting.
Important points include:
Log diameter
Paper alignment
Core position
Winding density
Surface condition
Tail condition
Actual toilet paper converting projects commonly inspect these characteristics during factory trial runs before equipment enters the packing stage.
6. Check the Electrical System
The electrical system should be inspected before the machine is packed.
Check:
Main electrical cabinet
PLC
Touchscreen
Motors
Inverters or drives
Sensors
Wiring
Terminals
Circuit breakers
Emergency-stop circuit
Electrical labels
Cooling fans
Grounding
Confirm the Voltage
This is especially important for export orders.
For example, a machine intended for a market using 380 V / 50 Hz / 3-phase should not be shipped with an incompatible electrical configuration.
The buyer should confirm the following before shipment:
Voltage + Frequency + Phase + Control voltage
The final electrical configuration should be consistent with the destination-country requirements agreed in the order.
7. Test Safety Devices
Safety functions should not be treated as optional checks.
Depending on the machine configuration, inspect:
Emergency-stop buttons
Safety guards
Safety switches
Protective covers
Warning labels
Accessible moving-part protection
Alarm functions
An emergency stop should be tested during the agreed acceptance procedure to confirm that the machine responds as specified.
For automated tissue equipment, safety-system integrity is commonly included among pre-shipment quality checks together with perforation, embossing, roll density and other production functions.
8. Check Machine Controls and Operating Functions
The control panel should be checked during the trial.
Confirm that:
The touchscreen works correctly.
Buttons respond normally.
Machine parameters can be adjusted.
Sensors provide the expected signals.
Alarms appear correctly.
Emergency stops work.
Start/stop functions work.
Manual and automatic functions operate as agreed.
If the machine has multiple operating modes, each agreed mode should be demonstrated.
Buyers should also ask the supplier to record important operating parameters during the trial. This creates a useful reference for installation and commissioning at the customer's factory.
9. Check Production Capacity Under Defined Conditions
Do not judge machine capacity only by the number shown in a brochure.
Production output depends on the actual product specification and operating conditions.
Factors may include:
Machine speed
Jumbo roll specification
Paper basis weight
Number of plies
Finished-roll diameter
Perforation length
Embossing requirements
Changeover time
Operator experience
Material quality
For this reason, the buyer should define the test conditions before the factory acceptance test.
For example:
Test material: 2-ply tissue
Jumbo roll width: 2200 mm
Finished roll diameter: 100 mm
Perforation length: 100 mm
Required production condition: agreed machine specification
The resulting production data can then be compared with the purchase agreement.
This is more meaningful than simply recording the machine's maximum mechanical speed. Tissue converting suppliers also distinguish between design speed and practical output because product specifications and material conditions can affect actual production results.
10. Check Spare Parts and Accessories
Before shipment, compare the actual spare parts with the agreed spare-parts list.
Typical items may include:
Belts
Bearings
Sensors
Fuses
Electrical components
Cutting components
Sealing or gluing components
Tools
Special adjustment tools
Other wear parts
Do not simply ask:
"Are the spare parts included?"
Instead, use a detailed checklist and physically verify the quantities.
For example:
| Item | Ordered Quantity | Actual Quantity | Status |
|---|---|---|---|
| Sensor | 2 | 2 | OK |
| Bearing | 4 | 4 | OK |
| Belt | 2 | 2 | OK |
| Special tool | 1 | 1 | OK |
| Electrical fuse | 10 | 10 | OK |
This reduces the possibility of discovering a missing item after the machine arrives overseas.
11. Check Documents Before Shipment
The machine itself is not the only thing that needs inspection.
Ask the supplier to prepare the agreed document package.
Depending on the project, this may include:
User manual
Electrical drawings
Machine specifications
Spare-parts list
Packing list
Commercial invoice
Test report
Installation instructions
Maintenance instructions
Electrical documentation
Certificates requested in the contract
The exact documents required will depend on the buyer's country, machine configuration and purchase agreement.
Documentation should be checked before shipment rather than waiting until the machine arrives.
12. Inspect Export Packaging
Once the machine passes the functional inspection, inspect the export packaging.
Check:
Machine protection
Moisture protection
Rust prevention
Shock protection
Wooden cases or pallets
Internal fixation
Loose-part packaging
Spare-parts packaging
Shipping marks
Package numbers
Packing list
Large tissue converting machines may contain multiple machine sections and accessories, so each package should be clearly identified.
Take photographs before the container is closed.
It is useful to record:
Machine before packing
Machine after protective wrapping
Internal package protection
Spare parts
Accessories
Package markings
Container loading
Final container sealing
Pre-shipment inspection guidance generally recommends checking the machine against the approved order, verifying accessories and documentation, recording non-conformities, and inspecting export packing before shipment authorization.
13. Record Any Non-Conformities
If something does not match the agreed specification, record it formally.
A simple inspection report can use:
| Issue | Required Action | Responsible Party | Status |
|---|---|---|---|
| Wrong electrical label | Replace label | Supplier | Open |
| Missing spare bearing | Add bearing | Supplier | Open |
| Perforation needs adjustment | Re-test machine | Supplier | Open |
| Packing mark missing | Add shipping mark | Supplier | Open |
Do not rely only on verbal promises.
The important point is to establish a clear record of what must be corrected before the machine is released for shipment.
A factory acceptance test is stronger when it has predefined acceptance criteria, measured results, documented non-conformities and a clear release decision.
14. Use a Pre-Shipment Inspection Checklist
A buyer can use the following simplified checklist:
Toilet Paper Machine Pre-Shipment Checklist
Machine configuration
Model confirmed
Machine width confirmed
Finished-roll specifications confirmed
Core diameter confirmed
Embossing configuration confirmed
Perforation configuration confirmed
Mechanical inspection
Frame checked
Rollers checked
Bearings checked

Fasteners checked
Guards installed
Production trial
Empty running test completed
Tissue trial completed
Paper alignment checked
Embossing checked
Perforation checked
Roll diameter checked
Roll density checked
Electrical and safety
Voltage confirmed
PLC checked
Sensors checked
Emergency stop tested
Safety guards checked
Alarm functions checked

Spare parts checked
Tools checked
Documents checked
Packing checked
Shipping marks checked
Packing list confirmed
Final photographs taken
15. Example: A Practical Pre-Shipment Inspection
Consider a buyer ordering a toilet paper rewinding machine for producing standard household toilet rolls.
The agreed configuration includes:
2-ply tissue
2200 mm working width
100 mm finished roll diameter
Specified core diameter
Embossing
Perforation
Automatic control system
During the factory inspection, the buyer should not only confirm that the machine starts.
A practical inspection could include:
Step 1: Verify the model and machine configuration.
Step 2: Run the machine without paper to check motors, rollers, sensors and transmission.
Step 3: Run the machine with representative jumbo tissue.
Step 4: Collect several finished rolls.
Step 5: Measure roll diameter and check paper alignment.
Step 6: Inspect embossing and perforation.
Step 7: Check roll density and winding quality.
Step 8: Test emergency stops and agreed safety functions.
Step 9: Verify spare parts and accessories against the packing list.
Step 10: Check manuals, electrical documents and other agreed paperwork.
Step 11: Inspect protective packaging.
Step 12: Record all open issues and confirm corrective actions before shipment.
This process gives the buyer objective evidence that the equipment presented for shipment matches the agreed order.
16. FAT and Pre-Shipment Inspection Are Not Exactly the Same
The terms Factory Acceptance Test (FAT) and pre-shipment inspection are sometimes used interchangeably, but they can have different purposes.
A FAT focuses mainly on whether the machine meets predefined functional and performance requirements at the supplier's factory.
A pre-shipment inspection can additionally cover:
Machine identity
Quantity
Appearance
Accessories
Spare parts
Documentation
Packing
Shipping marks
For an overseas buyer, both are useful.
The FAT verifies that the machine can perform the agreed functions, while the final pre-shipment inspection confirms that the actual equipment, accessories and shipment package are ready for delivery.
Conclusion
A toilet paper machine inspection before shipment should go far beyond checking whether the machine can run.
Buyers should verify:
Machine configuration
Mechanical assembly
Empty-machine operation
Real paper trial
Finished-roll quality
Production conditions
Electrical system
Safety functions
Spare parts
Documents
Export packaging
Corrective actions
The best approach is to define the inspection criteria before the machine is completed and record measurable results during the factory trial. This gives both buyer and supplier a clear reference before the equipment is packed and shipped.
For international buyers, a properly documented toilet paper machine factory acceptance test can also make installation and commissioning easier because the customer receives a record of the machine configuration, trial conditions and tested functions.
When purchasing a toilet paper making machine, always compare the final machine against the approved quotation and technical specification—not just the supplier's product photos or standard model description.
