A “round stand” does not mean that every braid made on it must be round. Kumihimo Hirai’s equipment guide identifies both round and flat braids as possibilities on a marudai.
Technique and structure
On the marudai, yarn comes through the opening in the upper board and the developing braid descends. The takadai uses a different arrangement: the worker sits within the stand, with yarn carried to either side, and follows ayagaki instructions while using a bamboo tool to settle the structure. The equipment names describe working arrangements, not interchangeable labels for one process.
Separate shape from the working method
Hirai describes the takadai as capable of complex patterns using many bobbins. That does not establish the stand used for an unlabelled cord, or mean that a flat braid must have been made on a takadai.

組紐の丸台と高台：紐の進む方向と整え方
くみひも平井の解説では、丸台は上板の穴から糸を出し、組んだ紐を下へ進めます。高台は左右に糸を掛け、綾書きに従って竹のヘラで目を整えます。丸台でも丸組と平組ができ、台の名前だけで紐の断面や繊維組成を決めつけないことが大切です。
