ABSTRACT:
A three-dimensional weaving machine that enables biased yarn guide blocks to be reduced in size and their movement to be simplified and that reliably feeds biased yarns is described. A three-dimensional mechanism contains 2N guide blocks (13), each including a biased yarn through-hole (15) extending along the length direction. A guide block receiving and supporting device (18) forms guide block arrangement spaces (S1), (S2), and (S3) in a bottom stage, a middle stage, and a top stage wherein N of the 2N guide blocks can be arranged in each stage parallel with, and adjacent to, one another. A guide block moving device (22) is provided for moving the guide blocks in each stage in opposite directions along the respective stages, and a shifting device (44) operates for simultaneously shifting two adjacent sets of guide blocks movably arranged in the respective guide block arrangement spaces, each by one stage.
