Pallet Wrapper fault
Pallet Wrapper Not Cutting Film
When a pallet wrapper fails to cut or clamp the film at the end of a cycle, the cause is usually a failed cutter blade, worn clamp mechanism, actuator fault or a sensor not detecting the film position correctly.
Does this match your fault?
Common symptoms
✓
Film tail left on load after cycle completes
✓
Cutter moves but does not cut through the film
✓
Film clamp does not grip before cutter fires
✓
Cycle completes but operator has to pull film off manually
✓
Intermittent cutting — works sometimes but not consistently
✓
Film wraps back around the load after cutter fires
What causes this
Typical causes
Worn or damaged cutter blade
The cutter blade dulls over time, particularly with high usage or incorrect film spec. A dull blade pushes rather than cuts, resulting in tails or incomplete separation.
Clamp not gripping film before cut
If the film clamp does not hold the film tightly before the cutter fires, the film moves and the cut misses. Worn clamp pads or low air pressure (on pneumatic machines) is the usual cause.
Actuator or solenoid fault
The actuator that drives the cutter or clamp has failed, is slow, or is not receiving the signal to fire. Can be mechanical wear or an electrical fault.
Film detect sensor misreading
A dirty or misaligned sensor may not detect the film correctly, causing the cut/clamp sequence to fire at the wrong time or not at all.
Before calling an engineer
What to check first
These are the practical checks worth trying before calling out an engineer. If none of these resolve the fault, or if the issue keeps returning, it needs a proper diagnosis.
01
Check the cutter blade condition
Inspect the blade for nicks, dullness or damage. On most machines the blade is accessible with the machine isolated. A blade that looks intact may still be too dull to cut cleanly.
02
Check clamp pad condition and grip
Inspect the rubber or foam clamp pads for wear, hardness or contamination. They should grip the film firmly. On pneumatic machines, check air pressure is within spec.
03
Clean the film detect sensor
Locate the film detection sensor near the cut/clamp area and clean it with a dry cloth. Check its alignment — it should be reading the film position, not the carriage or background.
04
Watch a full cycle slowly
Run the machine slowly if possible and observe the sequence. Does the clamp fire before the cutter? Does the cutter complete its full travel? This tells you which component is the problem.
When to call us
If any of these apply, call now
At this point, continued resets or workarounds are unlikely to resolve the underlying fault. A proper diagnosis is faster and cheaper than repeated call-outs for the same issue.
Cutter fires but film is clearly not being cut — blade or actuator issue
Clamp does not move at all during the cut sequence
Intermittent cutting that cannot be resolved by cleaning sensors or adjusting settings
