Lancets, or gauges, are thin metal strips used on face-to-face carpet weaving looms to ensure constant pile height. Before they were introduced on face-to-face looms they had been used on loop-pile looms (Brussels carpets). On loop-pile looms, pile loops are formed over a dummy weft resting on the lancet (Fig. 1). Usually the dummy weft is removed afterwards. This way of weaving loop pile was invented by Mullers & Spindler of Dulken/Germany in 1894. Instead of a lancet, a binding warp thread was used to support the dummy wefts.
