Jacquard Machine and Harness

Originally the Jacquard machines were mechanical, and the fabric design was punched in pattern cards which were joined together to form a continuous chain. The Jacquards often were small and only independently controlled a relatively few warp ends. This required a number of repeats across the loom width. Larger capacity machines, or the use of multiple machines, allowed greater control, with fewer repeats, and hence larger designs to be woven across the loom width.
