    摘要： The weft-inserting rods of a shuttleless loom are driven rectilinearly by a crank arrangement including a cycloid gear to produce a variable-speed straight line drive. A drive gear on the loom shaft drives a gear train mounted on the loom frame and includes a shaft having a crank arm affixed thereon. The crank arm, through an adjustable link, drives a crank arm fixed on a stub shaft mounted in the lay of the loom. As the last-named crank arm rotates, a gear fixed on the lay drives a further gear, by means of a toothed belt. The first gear is connected to a crank arm in which the second gear is rotatably mounted. A lever arm fixedly connected to the second gear is pivotally connected to the weft-inserting rod. The mechanism, beginning with the stub shaft mounted in the lay, partakes of motion of the lay.
