![]() The jacquard loom provides unlimited patterning possibilities. Thus, the Jacquard loom could be considered as the grandfather of computer-based machinery. The use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability. ![]() The invention of the Jacquard loom was an important step in the development of computers. Jacquard loom invented by Joseph Marie Jacquard at 1801. The lifting of each heddle was once controlled by a series of punched cards, but these systems have virtually all been replaced by microcomputer systems that control the lifting of heddles and corresponding warp yarns. A Jacquard loom does not have shafts, it has individual heddles, and each heddle of the loom and corresponding warp yarn is individually controlled by the Jacquard mechanism. A Jacquard loom is used to produce fabrics that have intricate patterns and weave structures that use over 24 shafts. The majority of woven fabrics are produced on one of three loom types: a tappet loom, dobby loom or a jacquard loom.
