Anotations

Scope note:

Metal frames on which multiple bobbins, or cylindrical spindles for winding yarn or thread, are fitted and wound parallel to one another. These frames often incorporate manual or automated yarn tension devices arranged between each bobbin fixing shaft, which help standardize the yarn's directional path and tension to overcome friction and facilitate subsequent yarn processing and warping.
