Strapping Machine fault
Strapping Machine Not Feeding Strap
A strapping machine that fails to feed strap around the arch or to the sealing head is usually a feed roller, guide, tension or strap path issue — not an electrical fault, and often resolvable with systematic checks.
Does this match your fault?
Common symptoms
✓
Strap does not advance when feed is commanded
✓
Strap starts to feed then stops partway
✓
Strap feeds but does not reach the head or arch
✓
Feed roller spins but strap does not move
✓
Machine alarms immediately on feed command
✓
Strap feeds fine without a load but fails with one
What causes this
Typical causes
Feed roller slip or wear
Worn or contaminated feed rollers lose grip on the strap. The motor runs but the strap does not advance. Roller surfaces should have a consistent texture — smooth or glazed rollers need replacing.
Strap path obstruction
Strap fragments, debris or kinked strap from a previous jam are partially blocking the strap path. The strap cannot advance past the obstruction.
Guide or track misalignment
The strap guide channels or arch track have shifted or a section has been dislodged. Misalignment causes the strap to fold, kink and stop feeding.
Incorrect strap specification
Strap that is too wide, too thick or of poor quality creates excessive drag in the guide path. The feed rollers cannot overcome the resistance.
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
Clear the strap path completely
Remove the strap from the machine entirely. Clear any strap fragments from the arch, guides and head. Reload fresh strap following the threading diagram exactly.
02
Inspect feed roller surfaces
With the machine isolated, examine the feed roller surfaces. They should feel grippy, not smooth or glazed. Check roller pressure adjustment — rollers that are too loose will not grip the strap.
03
Check the arch and guides for obstructions
Run your finger around the inside of the arch channel. Feel for any burrs, displaced guide sections, debris or build-up that would obstruct the strap path.
04
Check the strap specification
Confirm the strap width and thickness matches the machine specification. Refer to the machine manual or the strap markings. Wrong spec is a common cause after a consumables change.
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.
