“Tibetan 'slit-loop' knot: continuous yarn looped over a gauge rod, then cut.” Research note. britannica.com/art/Tibetan-carpet.

Research notes

How it works: Britannica says the yarn is looped under a warp, brought toward the weaver over a metal gauge rod, and looped round the next warp. After a row, a knife run along a groove in the rod cuts the loops into pile. Tamarian Carpets patents describe the same knot as yarn looped round two warps and a temporary rod (e.g. a 3 mm aluminium rod). Kvadrat says a 'punja' is then used to beat the row down. Conflict: dealer pages differ on whether each loop grips one warp or two. Dating: Britannica says archaeological fragments in a similar technique survive from Coptic Egypt and Central Asia. No dated early Tibetan rug was found here (the repo already covers the 1860 Tibet note: ner-cn-tibet-1860).
