[1] The son of an organ maker, Bouchon partially automated the tedious setting up process of the drawloom in which an operator lifted the warp threads using cords.
The cords of the warp were passed through the eyes of horizontal needles arranged to slide in a box.
[2] This was similar to the piano roll developed at the end of the 19th century and may have been inspired by the patterns that were traditionally drawn on squared paper.
Three years later, his assistant Jean-Baptiste Falcon expanded the number of cords that could be handled by arranging the holes in rows and using rectangular cards that were joined together in an endless loop.
Though this eliminated mistakes in the lifting of threads, it still needed an extra operator to control it and the first attempt at automation was made by Jacques Vaucanson in 1745.
