Part of a series from Posselt's Textile Journal (June 1915) explaining how broken twill weaves are designed for dobby looms. It sets out rules for choosing a balanced even-sided foundation twill, reversing its direction with a clean break, and the break-thread rule (skip half the repeat minus one). It then describes Figs. 1 to 22, covering broken warp ways only and broken warp and filling ways (check effects), with harness requirements and draft arrangements. The pages are interleaved with trade advertisements and a short item on industrial alcohol use in Russia.
