Among the many solutions proposed by Leonardo for mechanizing the process of weaving, the automatic loom is perhaps one of the most innovative.
By means of a series of mechanisms set into synchronized motion by a driving wheel, two arms alternately grasp the spool carrying the weft thread from one edge to the other of the warp. In this way, strips of fabric of reduced width are obtained.
Since the spool is gripped and accompanied, the path it can travel is relatively short, so this type of loom is capable of mechanizing the weaving process only for ribbons.
Between the end of the 17th century and the first half of the 18th century, this solution conceived by Leonardo found application in the mechanical looms of the French Jean Baptiste De Gennes and Jacques Vaucanson.
