What type of machine did Leonardo da Vinci design to improve the efficiency of weaving?

Leonardo da Vinci designed an automatic loom to improve the efficiency of weaving.

Leonardo’s mechanical studies included textile machinery intended to automate repetitive operations. A loom holds lengthwise threads under tension while a shuttle carries the crosswise thread through them. Automating these motions could make weaving faster and more consistent.

His loom-related designs reflect the Renaissance interest in mechanizing skilled work. Leonardo carefully studied gears, cams, shafts, and linkages, all of which could convert continuous rotation into repeated actions. The surviving drawings are design studies rather than evidence of a mass-produced Leonardo loom.

The invention is sometimes confused with the later power loom. Industrial power looms, developed centuries afterward, used water or steam power and became central to factory textile production. Leonardo’s proposal belongs to an earlier experimental tradition of mechanical automation.
