The Jacquard Loom is a mechanical loom that uses pasteboard cards with punched holes, each card corresponding to one row of the design. Multiple rows of holes are punched in the cards and the many cards that compose the design of the textile are strung together in order. The Jacquard process and the necessary loom attachment are named after their inventor, Joseph Marie Jacquard (1752–1834). This mechanism is probably one of the most important weaving inventions as Jacquard shedding made possible the automatic production of unlimited varieties of pattern weaving. The term “Jacquard” is not specific or limited to any particular loom, but rather refers to the added control mechanism that automates the patterning. The process can also be used for patterned knitwear and machine-knitted textiles, such In former times, if figured designs were required, this was done on a draw loom. The heddles with warp ends to be pulled up were manually selected by a second operator (draw boy), apart from the weaver. It was slow and labour-intensive, with practical limitations on the complexity of the pattern.
