Jacquard Loom Cards

In 1801, Joseph Marie Jacquard, a silk-weaver, invented an improved textile loom. The Jacquard loom was the first machine to use punched card. These punched cards controlled the weaving, enabling an ordinary workman to produce the most beautiful patterns in a style previously accomplished only with patience, skill, and hard work.

The loom was controlled by a "chain of cards", a number of punched cards, laced together into a continuous sequence.[5] Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Several such paper cards, generally white in color, can be seen in the images below. Chains, like Bouchon's earlier use of paper tape, allowed sequences of any length to be constructed, not limited by the size of a card.
