This includes shuttles (devices that carry weft yarn across the loom), weavers' hand tools (such as beaters, heddles, and combs), and supporting apparatus that facilitate or enhance the weaving process. The classification covers both traditional and mechanical devices designed to improve weaving efficiency, yarn handling, and fabric quality. Related weaving machinery and loom frames are covered separately under other D03 subclasses.
