Abstract
A method for the formation of a three-dimensional woven fabric comprises causing arms of carriers disposed around one component yarns out of three mutually perpendicular component yarns and having the other two component yarns separately held thereon to be rotated, opposing carrier arms of adjacent carriers to each other thereby effecting transfer of yarns, and successively effecting said transfer of yarns to carrier arms of the subsequent carriers thereby enabling the two component yarns to be displaced and zigzagged relative to the remaining one component yarn. An apparatus for effecting the aforementioned method essentially comprises a multiplicity of carriers arrayed longitudinally and laterally on a carrier holding plate and means for imparting necessary movements to the carriers. The three-dimensional woven fabric can be formed in a desired shape or yarn arrangement by suitably varying the pattern of arrangement of the two component yarns.
