🧵 Jacquard Loom: Punched Cards, Float Lengths, Cloth Weight and Output (2D)

Top view of a Jacquard loom row by row: a punched card lifts some of 24 hooks, the lifted warp threads show red on the cloth and the rest show the cream weft. Choose a pattern (diamond, chevron, basket, twill, satin or plain), set the thread density, yarn, loom speed, efficiency and width, and read the longest float, the interlacing, the cloth weight, the cover factor and the metres woven per hour. Four in-page numerical checks compare counts and integrals with the formulas.
