The grande tire drawloom: the design as a set of cords and the work of the drawboy

c. 1605 Knowledge infrastructure instrument

A loom on which the design is held not in the shafts but in a set of cords: each cord lifts its own group of warp threads. Two people work, the weaver and the drawboy (French tireur) who pulls the cords in the order the design requires.

The Lyon version is associated with the French master Claude Dangon (around 1605). He raised the number of cords to about two thousand four hundred against the earlier eight hundred, and Lyon became able to weave large figured silks on a par with the Italians.

What matters more than the richness of the cloth is the arrangement of the work: the design is already recorded apart from the machine and apart from the weaver, yet it is a human being who executes the record. The second worker cost money and made mistakes, and the whole 18th century was spent searching for a device that would do his work by itself. A straight line runs from there to Bouchon's punched tape and to the Jacquard loom.

Why this date

Approximate, and it refers to the Lyon version rather than to the loom type in general. The Museum of the History of Lyon states that the grande tire loom appears at Lyon about 1605; in 1607 Claude Dangon received the title of royal master workman and a five year privilege from Henri IV. The drawloom itself is far older: according to Britannica its origin is unknown, probably East Asian, and it reached the Italian silk centres in the Middle Ages. The date here belongs to the Lyon loom because it was that loom which the Jacquard machine replaced two hundred years later.
