How did a weaving loom lead to one of the greatest technology innovations of the 21st century?
The Jacquard Loom was a significant breakthrough in the history of textile production, an essential manufacturing tool of the Industrial Revolution. Joseph Marie Jacquard, a silk weaver from Lyon, France, first demonstrated his improved drawloom at an industrial exposition in Paris in 1801. By 1803, a spark of genius inspired him to make another improvement to this loom—the “Jacquard attachment.”
This mechanism, mounted above the loom, uses a continuous chain of punch cards to control the lifting of individual threads. Each card on the loom corresponds to a hook, which can be raised or stopped depending on whether the hole is punched out or solid. The cards are mounted on a rotating cylinder and pressed against pins, which detect the presence of holes. The loom’s hooks are raised or lowered by a harness, which guides the thread to form a pattern in the fabric.
