Quite right Stan,
I was an indentured apprentice at 14 in a Cotton Weaving Shed which had over 200 Looms. and its own Spinning Mill.
The older weavers used the word Fettler, but later it was often referred to as Loom Overlookers, who were given a "set" of Looms to attend to. The term often used was the Loom was in good" fettle" when it was performing well. and the humidity in the "Shed" was damp enough to help stop the cotton ends breaking in the Warp(on the Beam) or Weft. in the Healds, or reeds, and in the shuttle.
