Term	Main definition
cards	Cards used in conjunction with a machine invented by Joseph Marie Jacquard (1752 1834) between 1801 and 1810, for weaving, complex and elaborate patterns. A Jacquard mechanism, similar to the simpler dobby system, operated by punched holes in card. Each hole in each card allows for selection of a single warp thread. Each card represents one pick in the weft. The most common sizes of cards have space for 200, 400 or 600 holes in each. Further developments of the Jacquard mechanism have been made, some of which are used in knitting machines. Modern Jacquard looms are operated electronically with computers determining the patterns. See Jacquard.
