An International Correspondence Schools instruction paper on fixing power looms in woolen and worsted mills. It covers the duties of the loom fixer, erecting and starting looms, putting in warps, and the adjustment and faults of the shedding, box, picking, binder, shuttle, take-up and let-off mechanisms. Later sections deal with troubleshooting problems such as banging off, flying shuttles, broken picker sticks, cut or kinky filling, thick and thin places, poor selvages and weak warps, with closing notes on oiling, cleaning and supplies.
