Weaver in front of a Jacquard loom

A weaver supervises the operation of a Jacquard loom, in 1946. The Jacquard loom is a loom developed by Joseph Marie Jacquard from Lyon in 1801. It was the first punched cards control mechanical system, which was later perfected by the textile industry for the mechanization of looms. The punched cards guide the hooks that raise the warp cords. They enable the weaving of complex patterns such as brocade or damask.
