Leonardo conceived this complex machine, in his endeavour to improve textile machines and to eliminate all restrictions deriving from having to card preset lengths of cloth. The machine consisted in a rugged, triangular stand supporting two cylinders, placed one above the other. The length of cloth, whose ends are connected to the two cylinders, unwinds from the upper roller and winds onto the lower one. During the unwinding/winding motion, the cloth is processed (teased) by means of a set of carders on a heavy bar positioned above the upper cylinder.
The model is based on the drawing:
