Installing a toilet paper making machine correctly is essential for stable production, consistent roll quality, and long-term equipment reliability. A machine that is not properly leveled, aligned, connected, or tested can experience excessive vibration, web breaks, uneven winding, electrical faults, and premature component wear.
A proper installation should therefore include more than simply placing the machine on the factory floor and connecting the power supply. The foundation, mechanical alignment, electrical system, compressed air, paper path, safety devices, and trial-production results should all be checked before commercial operation.
For paper converting equipment, machine safeguarding is also an important part of commissioning. HSE guidance for paper-converting machinery emphasizes guarding of moving parts, interlocking devices, emergency stops, and safe procedures for setup, cleaning, blockage removal, and maintenance.
1. Check the Installation Area Before Delivery
The first step is to make sure the production area is suitable for the machine.
Before installation, confirm:
Available floor space
Machine footprint
Ceiling height
Door and transportation access
Floor load capacity
Power supply location
Compressed-air availability, if required
Lighting and ventilation
Space for raw material and finished products
Maintenance access around the machine
The machine should not be installed so close to walls or other equipment that operators cannot safely inspect, clean, adjust, or maintain it.
Example
Suppose a toilet paper machine has a machine footprint of approximately 8 m × 4 m.
A factory should not plan for only 32 m² of usable space. Additional working and maintenance areas are normally needed around the machine.
For example:
| Area | Example requirement |
|---|---|
| Machine footprint | 8 × 4 m |
| Machine area | 32 m² |
| Raw material area | 15–25 m² |
| Finished product area | 15–25 m² |
| Operator/maintenance clearance | Additional space required |
| Total production area | Often significantly larger than machine footprint |
The exact clearance should follow the equipment supplier's installation drawing rather than using a universal number.
HSE guidance also recommends ensuring that fixed machinery is properly installed and stable, while electrical, pneumatic, and other power supplies should be properly identified and managed.
2. Check the Floor and Foundation
The foundation is one of the most important parts of toilet paper making machine installation.
A converting machine contains rotating shafts, rollers, motors, gears, bearings, and other moving components. If the machine base is unstable or uneven, vibration can increase during operation.
Check:
Floor strength
Floor flatness
Foundation dimensions
Anchor-bolt positions
Anchor-bolt diameter and depth
Machine mounting points
Levelness of the machine
Vibration after installation
If the machine requires a concrete foundation, follow the supplier's foundation drawing rather than estimating the dimensions at the installation site.
Practical example
Consider a rewinding machine operating at 500 m/min.
At this speed, even a small mechanical alignment problem can become more noticeable than it would be during manual inspection. If the machine base is uneven, the resulting vibration may contribute to:
Uneven paper winding
Web deviation
Bearing wear
Noise
Loosened fasteners
Reduced product consistency
Therefore, the machine should be leveled and securely fixed before commissioning.
3. Check Machine Leveling and Mechanical Alignment
After the machine is positioned, check whether the major components are correctly aligned.
Important points include:
Main machine frame
Rewinding shaft
Paper guide rollers
Embossing rollers
Perforation system
Transmission system
Cutting system
Conveyor
Motor and gearbox
Couplings
Bearings
The centerlines of related rollers and shafts should be checked according to the manufacturer's installation requirements.
Why alignment matters
If two related rollers are not properly aligned, the paper web may move toward one side instead of running centrally.
This can result in:
Misalignment → uneven web tension → paper deviation → poor winding → unstable finished rolls
A simple installation check can therefore prevent a much more expensive production problem later.
4. Check Electrical Power Requirements
Electrical installation should be completed according to the machine's nameplate and electrical documentation.
Before energizing the machine, check:
Rated voltage
Frequency
Phase configuration
Total installed power
Main motor power
Heater power, if applicable
Control-panel voltage
Circuit-breaker capacity
Grounding
Cable size
Emergency-stop circuit
Motor rotation direction
Example
Suppose a machine is specified for:
380 V
50 Hz
Three-phase
Total installed power: 35 kW
The factory should confirm that its electrical supply is compatible before connecting the machine.
The actual electrical capacity should not be selected only according to the main motor rating because the machine may include multiple motors, heaters, pumps, fans, or auxiliary devices.
A qualified electrician should verify the final electrical installation.
5. Check Grounding and Electrical Protection
Grounding should be checked before production begins.
Verify:
Protective earth connection
Electrical cabinet grounding
Motor grounding
Cable insulation
Circuit protection
Emergency-stop circuit
Control-panel connections
Loose terminals
Correct phase sequence
Do not assume that a machine is electrically safe simply because the control panel powers on.
During commissioning, electrical protection should be tested under controlled conditions.
6. Check Compressed Air Requirements
Some toilet paper converting machines use pneumatic cylinders, air knives, clamps, or other pneumatic components.
If compressed air is required, check:
Air pressure
Air flow
Air quality
Moisture
Filter condition
Regulator setting
Air hose connections
Leakage
Drainage
For example, if a machine requires 0.6–0.8 MPa compressed air, the factory should verify that the actual supply can maintain the required pressure during continuous operation.
A pressure gauge showing the correct value when the machine is stopped does not necessarily prove that the system can maintain the required pressure when several pneumatic components operate simultaneously.
7. Check the Paper Feeding and Web Path
The jumbo roll or parent roll should be installed correctly before the first trial run.
Check:
Jumbo-roll width
Jumbo-roll diameter
Paper direction
Core diameter
Roll position
Shaft/chuck installation
Web path
Guide rollers
Tension system
Embossing position
Perforation position
The paper should travel through the machine according to the manufacturer's web-threading diagram.
Example
If the machine is designed for a 2,850 mm parent roll width but the supplied jumbo roll is only 2,650 mm, the material may not utilize the machine's designed working width efficiently.
Similarly, an incorrect core diameter can prevent proper mounting of the parent roll.
Therefore, material compatibility should be checked before installation rather than discovered during production.
8. Check Roller and Transmission Components
Before running the machine, manually inspect accessible mechanical components.
Check:
Bearings
Chains
Belts
Gears
Couplings
Shafts
Rollers
Fasteners
Lubrication points
Protective covers
Look for:
Loose bolts
Abnormal gaps
Damaged components
Missing guards
Excessive mechanical resistance
Oil leakage
Incorrect lubrication
If the machine has been transported over a long distance, shipping vibration can occasionally loosen components that were correctly adjusted before shipment.
9. Check Embossing and Perforation Systems
For toilet paper production, embossing and perforation directly influence finished-roll appearance and usability.
Before full-speed production, verify:
Embossing
Roller alignment
Embossing pressure
Pattern position
Paper tracking
Adhesive system, if used
Perforation
Knife or perforation roller condition
Perforation spacing
Cutting pressure
Paper tracking
Perforation consistency
For example, if the target perforation pitch is 100 mm, a production sample should be measured across multiple sections of the roll rather than checking only one point.
The goal is to confirm that the actual production result is consistent with the machine's specified range.
10. Check Safety Guards and Interlocks
Safety devices should be checked before the machine is allowed to operate at production speed.
Important items include:
Fixed guards
Interlocking guards
Emergency-stop buttons
Safety switches
Warning signs
Protective covers
Access doors
Start-up warning devices where applicable
Paper converting machinery can contain significant hazards at roller nip points, cutting areas, and other moving components. HSE guidance specifically identifies in-running roller nips and cutting hazards as areas requiring appropriate safeguarding.
For an interlocked guard, the machine should not be able to start when the guard is in an unsafe/open condition, according to the machine's safety design.
Emergency-stop devices should also be tested during commissioning to confirm that they perform their intended function. HSE guidance for paper machinery gives particular attention to emergency stops, speed-control systems, pre-start warnings, and guard interlocking.
11. Check the Log Saw or Cutting System
If the production line includes a log saw, the cutting section requires special attention.
Check:
Saw blade installation
Blade direction
Blade protection
Cutting pressure
Guarding
Conveyor alignment
Emergency stop
Finished roll positioning
Waste collection
The cutting system should never be tested with guards removed unless the manufacturer's documented commissioning procedure specifically permits a controlled test under appropriate safeguards.
Cutting machinery requires protection against access to dangerous moving components, and interlocking or fixed guards may be required depending on the machine design and risk assessment.
12. Check Lubrication Before Trial Running
Some machines are shipped with components that require lubrication after installation.
Check:
Gearbox oil
Bearing lubrication
Chain lubrication
Linear guides
Pneumatic lubricators, if applicable
Manufacturer-specified grease points
Do not automatically add oil or grease to every component.
Some modern bearings and motors may be designed as sealed or maintenance-free components. Always follow the machine manual and lubrication chart.
13. Perform a No-Load Test
Before loading paper, perform a no-load test if the machine design and manufacturer procedure call for one.
Start at low speed and check:
Motor rotation
Roller rotation
Belt movement
Chain movement
Noise
Vibration
Electrical current
Pneumatic operation
Emergency stop
Control buttons
Sensors
Alarms
Listen for abnormal sounds such as:
Grinding
Repeated knocking
Excessive bearing noise
Belt slipping
Chain impact
If an abnormal condition appears, stop the machine and identify the cause before continuing.
14. Perform a Trial Run With Paper
After the no-load test passes, conduct a controlled production trial.
Measure:
| Parameter | Example check |
|---|---|
| Production speed | 300–500 m/min |
| Paper width | According to machine specification |
| Roll diameter | According to target product |
| Core diameter | According to finished-roll design |
| Perforation pitch | According to product requirement |
| Roll density | Compare with target |
| Embossing | Visual and dimensional check |
| Web tracking | Stable/unstable |
| Finished roll appearance | Consistent/inconsistent |
These figures are examples, not universal machine specifications. The actual acceptance range should come from the purchased machine's technical specification.
15. Check Finished Roll Quality
A machine can run continuously without necessarily producing acceptable toilet paper rolls.
During commissioning, inspect the finished product for:
Uneven winding
Loose edges
Telescoping
Wrinkles
Paper breaks
Incorrect perforation
Uneven embossing
Excessive roll hardness
Loose roll centers
Uneven roll diameter
Example
Suppose a buyer requires:
Finished roll diameter: 110 mm
Core diameter: 45 mm
Perforation pitch: 100 mm
During commissioning, measure at least several rolls rather than accepting the first roll as the final result.
If the measured diameters are:
| Roll | Diameter |
|---|---|
| 1 | 109 mm |
| 2 | 111 mm |
| 3 | 110 mm |
| 4 | 110 mm |
| 5 | 112 mm |
The average is approximately 110.4 mm.
This gives the operator a much better indication of actual production consistency than inspecting only one roll.
16. Check Machine Speed Under Production Conditions
The machine's maximum speed should not automatically be used as the initial production speed.
For example, if the machine is rated at 600 m/min, commissioning might begin at a lower controlled speed such as 300–400 m/min, depending on the manufacturer's procedure and material.
Then gradually evaluate:
Paper tension
Web stability
Vibration
Perforation quality
Embossing quality
Roll density
Motor load
Finished roll consistency
This helps identify problems before the machine reaches its maximum operating condition.
17. Check Temperature, Motors, and Electrical Load
After running for a period of time, inspect the machine again.
Check:
Motor temperature
Gearbox temperature
Bearing temperature
Electrical cabinet temperature
Motor current
Abnormal vibration
Compressed-air pressure
Lubrication condition
For example, if the main motor normally operates around 18–20 A under the specified production condition but suddenly rises significantly without an increase in production load, the cause should be investigated.
Possible causes include:
Mechanical resistance
Misalignment
Bearing problems
Excessive tension
Incorrect electrical connection
The actual acceptable current must be compared with the motor nameplate and supplier documentation rather than using a universal current limit.
18. Check Emergency Stops and Restart Procedures
Emergency stops should be tested at appropriate commissioning stages.
After an emergency stop:
Confirm that the machine stops as designed.
Identify why the stop was activated.
Reset the emergency-stop device.
Confirm that the machine does not unexpectedly restart.
Check that the operating area is clear.
Restart according to the manufacturer's procedure.
Paper-machine safety guidance emphasizes that emergency stops should be positioned so they can be quickly reached by people working in the area.
19. Check Jam-Clearing Procedures
Paper jams are a normal possibility during converting operations, but jam removal should not be treated as ordinary running.
The commissioning team should establish a clear procedure for:
Stopping the machine
Isolating power
Waiting for moving parts to stop
Releasing stored energy where applicable
Removing the jam
Reinstalling guards
Checking the machine
Restarting
HSE accident analysis identifies blockage clearing, troubleshooting, maintenance, and operation after modification as situations where injuries can occur, particularly when machinery is not properly isolated or guarding is inadequate.
20. Check Operator Training and Documentation
Installation is not complete when the machine starts running.
The operator should understand:
Machine startup
Normal shutdown
Emergency stop
Paper threading
Roll changing
Tension adjustment
Embossing adjustment
Perforation adjustment
Jam clearing
Cleaning
Lubrication
Daily inspection
Basic troubleshooting
The machine should also be supplied with relevant documentation, such as:
Operation manual
Electrical drawings
Pneumatic drawings
Spare-parts list
Lubrication instructions
Installation drawings
Foundation drawings
Safety information
Recommended maintenance schedule
HSE guidance recommends providing operators with appropriate information, instruction and training and establishing safe systems of work for operating and maintaining machinery.

Installation Example: 1,500 mm Toilet Paper Rewinder
Consider a hypothetical toilet paper rewinding line with:
Working width: 1,500 mm
Production speed: 400 m/min
Finished roll diameter: 110 mm
Core diameter: 45 mm
Three-phase electrical supply
Pneumatic tension-control components
During commissioning, the installation team discovers that the paper web moves approximately 5–8 mm toward one side at higher speed.
Instead of immediately changing the winding parameters, the team checks:
Machine frame level
Guide-roller alignment
Parent-roll position
Web tension
Roller surface condition
Pneumatic pressure
Shaft alignment
The problem is eventually traced to incorrect alignment of one guide roller.
After realignment, the web tracking becomes stable at the target production speed.
This example illustrates an important installation principle:
A production-quality problem is not always a paper-quality problem. It can originate from machine installation and alignment.
Common Installation Mistakes to Avoid
1. Installing the machine without checking the foundation
An uneven or unstable base can create vibration and alignment problems.
2. Connecting power before checking the electrical specification
The factory should verify voltage, frequency, phase, grounding, and protection before energizing the equipment.
3. Starting at maximum speed
A controlled low-speed trial is generally more useful for identifying installation problems.
4. Ignoring safety guards
Guards and interlocks should be checked before production. Operators should not bypass safety devices simply to make setup or troubleshooting easier.
5. Testing only the machine without paper
A machine may operate smoothly without a load but behave differently when paper tension, roll weight, and production speed are introduced.
6. Accepting the first finished roll as the quality result
Several rolls should be inspected to evaluate production consistency.
7. Failing to document the commissioning results
Record actual installation and trial-production parameters so future maintenance teams can compare changes against the original baseline.
Final Takeaway
A successful toilet paper making machine installation should verify much more than whether the machine can be powered on.
The key checks include:
Installation area → foundation → leveling → mechanical alignment → electrical system → pneumatic system → paper path → safety devices → no-load test → production trial → finished-roll quality → operator training.
For a machine operating at several hundred meters per minute, small installation problems can become significant production problems. Checking alignment, tension, electrical connections, safety devices, and finished-roll quality during commissioning can help reduce unexpected downtime and improve production stability.
The final acceptance criteria should always be based on the machine manufacturer's technical documentation, the actual purchased configuration, and the applicable safety requirements in the installation country. HSE guidance similarly emphasizes proper installation, stability, guarding, isolation, risk assessment, and safe maintenance procedures for machinery.
FAQ
What is the most important check during toilet paper machine installation?
There is no single universal check. Foundation stability, machine alignment, electrical connections, paper-path alignment, safety systems, and trial-production performance should all be verified before normal production.
How long does toilet paper machine installation take?
Installation time depends on machine size, automation level, foundation requirements, electrical work, auxiliary equipment, and whether the machine is supplied as a complete line or separate units. The supplier's installation plan should be used rather than relying on a fixed number of days.
Should the machine be tested before loading paper?
Where the manufacturer's commissioning procedure permits it, a controlled no-load test can help verify motor rotation, mechanical movement, controls, vibration, and safety functions before production material is introduced.
What should be checked after the first production run?
Check web tracking, roll diameter, winding tightness, embossing, perforation, paper breaks, vibration, motor load, bearing/gearbox condition, and overall machine stability.
Who should perform the electrical installation?
Electrical connections should be carried out and verified by qualified personnel according to the machine documentation and applicable local electrical requirements.
Can a toilet paper machine be installed directly on a normal factory floor?
Some machines may be designed for direct floor installation, while others may require a specific foundation or anchoring arrangement. The machine supplier's foundation and installation drawings should determine the requirement.
