Loom Bar

Loom Bar — This is a defect characterized by a change of shade due to a build up of tension in the loom shuttle just before a filling change. There is always a difference in tension between a full bobbin and an almost empty one; however, this condition can be accentuated by a restriction in the shuttle eye, a weak or badly worn shuttle spring, a bobbin not ringing properly, a crooked bobbin, etc. It can be repetitive at each filling change or isolated depending on the exact cause.
