🧵 Jacquard Loom: Punched Cards, Hook Lift, Shed Geometry and Warp Thread Tension (2D)

Side and front view of a 16-hook Jacquard loom. Pick a card pattern, loom speed, warp tension, shed height and heddle distance, and watch the cards select hooks, the shed open, the thread stretch and the cloth grow. Pattern and shed timing follow the 3D loom page; thread tension, lifting work and cloth rate are computed with four in-page numerical checks.
