What type of machine did Leonardo da Vinci design to automate weaving on a loom?

Leonardo da Vinci designed an automatic loom concept to mechanize parts of the weaving process.

His notebooks contain studies of textile machinery, including mechanisms intended to coordinate repeated loom actions. A loom interlaces lengthwise warp threads with a crosswise weft thread. By using cams, gears, and linked moving parts, Leonardo explored how a machine could repeat operations that normally required a skilled worker’s hands.

The design belongs to Leonardo’s broader interest in automation and labor-saving machines. It was not an industrial loom in the modern factory sense, and historians should not treat every sketch as proof of a completed working device. Leonardo often recorded alternative mechanisms while testing ideas on paper.

The machine is sometimes confused with the spinning wheel, which twists fibers into yarn before weaving. A loom works with yarn to make fabric. That distinction identifies the invention’s place in textile production.
