loom-harness

Century Dictionary and Cyclopedia

1. n. That part of a loom which moves the warp-threads to make the crossing or decussation forming the shed in which the shuttle travels and leaves the weft-thread. The harness has heddles with loops for the warps, some of which are continually raised above the others and then depressed, either in regular alternation (for plain weaving) or in a different order, as the pattern requires.
