- Jacquard loom
-
a loom for producing elaborate designs in an intricate weave (Jacquard weave) constructed from a variety of basic weaves.[1850-55; named after J. M. Jacquard (1757-1834), French inventor]

It enabled production of fabrics with intricate woven patterns such as tapestry, brocade, and damask, and has also been adapted to the production of patterned knitted fabrics. Developed in France by J.-M. Jacquard in 1804–05, it used interchangeable punched cards that controlled the weaving of the cloth so that any desired pattern could be obtained automatically. It aroused bitter hostility among weavers, who feared that its labour-saving capabilities would deprive them of jobs; the weavers of Lyon not only burned the machines but attacked Jacquard as well. Eventually the loom's advantages led to its general acceptance, and by 1812 there were 11,000 in use in France. Use of the loom spread to England in the 1820s and from there virtually worldwide.* * *
▪ weavingalso called Jacquard Attachment, or Jacquard Mechanism,in weaving, device incorporated in special looms to control individual warp yarns. It enabled looms to produce fabrics having intricate woven patterns such as tapestry, brocade, and damask, and it has also been adapted to the production of patterned knitted fabrics.The Jacquard system was developed in 1804–05 by Joseph-Marie Jacquard (Jacquard, Joseph-Marie) (q.v.) of France, but it soon spread elsewhere. His system improved on the punched-card technology of Jacques de Vaucanson's loom (1745). Jacquard's loom utilized interchangeable punched cards that controlled the weaving of the cloth so that any desired pattern could be obtained automatically. These punched cards were adopted by the noted English inventor Charles Babbage (Babbage, Charles) as an input-output medium for his proposed analytical engine and were used by the American statistician Herman Hollerith (Hollerith, Herman) to feed data to his census machine. They were also used as a means of inputting data into digital computers but were eventually replaced by electronic devices.* * *
