A violent mechanical failure in a shuttle loom where the shuttle does not reach the opposite shuttle box in time. The loom's protection mechanism engages, slamming the machine to an abrupt halt to prevent the reed from crushing the trapped shuttle into the warp threads. This sudden stop causes intense vibration and can damage loom components or warp yarns.
Heard on the job
Loom four just banged off again, so we need to check the picker stick tension.
Insider tip
Frequent bang-offs usually point to a worn picker, low picking power, or a rebounding shuttle.
