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.

A traverse apparatus for a yarn winding machine which non-linearly buffers the impact between the cam drum (4) and cam roller (13) due to the emission resistance and shear resistance of the viscous fluid (b) intervening between shock absorbers (10a,10b,10a',10b') arranged at the return point and reciprocally moving slide members (9,9') connected to a traverse rod (14). As the impact between the cam drum (4) and cam roller (13) is sharply non-linearly buffered due to the to the emission resistance and shear resistance of the oil, noise generated when the cam roller returns can be reduced and the decrease in durability of the traverse device caused by the aforementioned impact can be prevented.
