Problem & answerI-08
Bottle Stuck Under the Sealing Head
Also covers: Burning risk
Likely causes
- Bottle tipped or wedged under the blue sealing head
- Head set too low for the bottle
- Guide rails too tight at the sealer
- Conveyor stopped while the head is energised
- Downstream jam backing bottles under the head
How to fix it
- 1Stop the induction sealer and conveyor immediately (emergency stop if needed).
- 2Switch off the sealing power before reaching in.
- 3Remove the stuck bottle with care: cap and foil may be very hot.
- 4Reject the stuck bottle and any bottle that stood under the head; check neighbouring bottles for heat damage.
- 5Find the cause: head height, guide rails, downstream jam.
- 6Raise the head to the correct height and set the rails.
- 7Restart and seal-test 2–3 bottles before production.
- 8Report the incident to the supervisor; record it in the logbook.
Technical note
A bottle that stops under an energised head keeps heating: the foil burns, the cap and bottle melt and there is a fire risk. Watch the sealer at all times while it runs and never leave a stopped bottle under the head.Photos
It is fixed when
Bottles pass under the head continuously; none stop or burn.
Stop it coming back
- Keep the sealer in view while running.
- Confirm the conveyor-stop interlock switches the head off.
- Clear downstream jams before they reach the sealer.
