Looms
The long threads attached to the frame are called the wrap – these are the ones running along the leanth of the loom that you weave the wool in and out of. The way this loom is set up there is a treddle which appears to be the treadle bar at the bottom though I wouldn't swear to that and a heddle which I think was the flate panel of wood in the middle that had the string running though it, alternatively in slots or wholes. When the peadle was pressed down it raised this panel so that the strings going through the wholes where raised whilst those in the slots stayed in the same place. This ment that instead of weaving in and out, over and under each alternate thread you could just pushed the thread though the middle and then either put your foot on or off of the pedle and repeat the process.
