What type of machine did Leonardo da Vinci sketch for weaving textiles automatically?

Leonardo da Vinci sketched an automatic loom for weaving textiles with less direct manual labor. His design used coordinated mechanical parts to move the shuttle and manage the threads in a repeating sequence.

The loom reflects Leonardo’s interest in mechanizing skilled work. Textile production depended on careful timing between the warp threads and the shuttle carrying the weft thread. By linking these actions through gears, cams, and levers, a machine could make the process more regular.

Leonardo’s drawing should not be confused with the fully industrial power loom developed centuries later. His proposal was an early mechanical concept, and surviving evidence does not show that it became a commercial production machine.

A spinning wheel makes thread; a loom turns thread into fabric. That distinction matters because Leonardo studied both textile-related processes, but the device in this question is specifically intended to automate weaving.
