Part of a serial article from Posselt's Textile Journal (January 1916) on double face reversible fabrics for harness and Jacquard weaving. It explains how face and back plies differ in color, weave and material, and how a third binder (centre or tying) warp joins them. Worked examples (Figs. 41-43) with warp and filling arrangements, weave plans and fabric sections cover 1 face:1 back and 2 face:1 back constructions using 4- and 6-harness twills and plain weave.
