Special rules of classification

Documents should only be classified here if the invention is specifically directed to braids, braiding, lace or lace making. Otherwise the documents should only be classified in the relevant application fields.

In contrast to weaving, braiding in general does not involve warp yarns extending in the lengthwise direction in conjunction with warp interlacing weft yarns always running in a single direction.
