Jacquard machine

A loom mechanism that uses punched cards to select warp threads automatically, enabling complex woven patterns to be reproduced.

Punched card: A stiff card whose holes encode information for mechanical reading. Holes in each card determine which warp threads the mechanism selects.
Joseph Marie Jacquard: A French weaver and inventor associated with the punched-card loom mechanism introduced in 1804. His name became attached to the mechanism and its industrial adoption.
Brocade: A figured fabric with raised patterns woven using supplementary weft threads. Jacquard control made elaborate brocade motifs easier to weave consistently.
Luddite movement: A British labor movement in the early nineteenth century that resisted machinery threatening workers’ livelihoods. Jacquard-style automation formed part of the wider mechanization reshaping textile work.
Jacquard loom: A loom equipped with a Jacquard mechanism for weaving patterned fabrics. The machine operates as the pattern-controlling attachment of this loom.
Basile Bouchon: A French inventor who used perforated paper to control a loom in 1725. His design established an early path toward punched-pattern control.
Damask: A reversible figured fabric whose pattern is formed by contrasting weave structures. The mechanism can select warp threads to produce damask’s intricate reversible designs.
Programmable machine: A machine whose operations can be changed by encoded instructions rather than rebuilt. Replaceable punched cards made the loom’s pattern sequence programmable.
Warp and weft: The lengthwise and crosswise yarn systems interlaced to form woven cloth. The mechanism selects warp threads so the weft can form a pattern.
Jean-Baptiste Falcon: A French inventor who developed a chain of punched cards for controlling a loom in 1728. His linked-card system anticipated the machine’s replaceable pattern instructions.
