Examine synthetic-fiber threads.
What does a Thread Inspector do?
Examines synthetic-fiber thread, passing continuously in front of electric light, for such defects as weak spots, lumps, irregular twisting, grease stains, and snags. Rejects lots of thread not meeting plant standard. May inspect washed and dried cakes of yarn for loose ends and remove excess thread with scissors and be designated Cake Inspector. May grade skeins of yarn by weight or presence of irregularities and be designated Sorter.
