About this book
The title presents an analysis and explanation of the Jacquard machine, with an appendix on preparing cards and practical hints for learners of Jacquard designing. The explanation of operation describes needles controlling the hooks, with springs pressing the needles towards cards carried on a perforated cylinder that moves like a pendulum.
The account of punched cards explains that a needle entering a hole leaves its corresponding hook positioned over the griffe-bar, allowing the hook to rise with the griffe. The discussion of two-ply ingrain carpets relates the grades called super and fine to the numbers of rows, needles and warp threads used in production. The carpet discussion notes that thread numbers sometimes vary because of pattern requirements or because economy may induce the maker to use a smaller number.
