Two-page installment (No. XXII) of Alfred Barlow's series on weaving in Engineering, covering pile weaving: velvets, terry velvet, Brussels and tapestry carpets. It explains the velvet loom with separate ground and pile beams, the insertion of grooved wires, and the cutting of loops with the trevette knife. It then describes the cloth beam with needle-point laths, the headle motions, and the construction of tapestry carpet (printed pile threads) and Brussels carpet (Jacquard-selected pile colours), with brief mention of Axminster and Wilton. Illustrated with numbered engineering figures (Figs. 218-231).
