D03J AUXILIARY WEAVING APPARATUS; WEAVERS' TOOLS; SHUTTLES
Description
D03J encompasses auxiliary equipment, tools, and components used in weaving operations beyond the primary loom structure itself. 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.
