 Jacquard's machine also contained eight rows of needles and uprights, where Vaucanson had double row, a modification that enabled him to increase the figuring capacity of the machine.In his first machine, he supported the harness by knotted cords, which he elevated by a single trap board.One of the chief advantages claimed for the Jacquard machine was that unlike previous damask-weaving machines, in which the figuring shed was usually drawn once for every four shots, with the new apparatus, it could be drawn on every shot, thus producing a fabric with greater definition of outline.
