A loom requires a considerable amount of repairs and renewals, the performance of which is delegated to an overlooker (sometimes called a tackler or tuner) placed over each hundred looms. If on fancy goods, fewer looms are under the control of one man; if plain narrow goods are woven, more. His work is to keep the looms supplied with warps, gait them up, repair or tackle the loom when necessary, provide weavers, and, especially in a small place, perform rather multifarious duties. When the weavers’ beam has been placed in the loom, having the healds and reeds attached to the warp, the overlooker draws the gears forward, placing a weight rope or chain round one beam ruffle, and, if a loomed beam, fixes the reed. The healds are slung loosely to the heald roller straps, and then the twist attached to the sand roller. If old healds are used, the lap end of a former cut is placed on the roller, and the warp tightened. If new healds have had the warp _drawn in_, a lap end is attached to the roller and the twist tied to it, care being taken to draw up any ends which may be ruffled. The temple is fixed so as to revolve in the direction required to distend the cloth. Then with the cranks near the top centre, the healds are levelled by means of the cords below being attached to the lambs and treadles. After a little manœuvring so as to make the shed _bottom_ nicely, whichever heald is down, to get the healds level all across, and clear of any obstruction or drooping ends, the lease rods are put in. The second and back healds are raised when the back rod has to be put through the front, the third being up for the thin rod. A few picks of weft being put through by hand, a start is made after finishing the weighting of the beam and changing the pinion, if necessary. The weighting is somewhat important; for light cloths, fine yarns and light picks less weight is required than for the heavier classes of goods. More weight is required for full beams and under certain other conditions.
