  • a traverse mechanism for winding and like machines comprising a rod formed with a screw-thread on its periphery, means to reciprooate said rod, a relatively stationary ratchetwheel mounted on said rod and rotatively connected therewith, said rod being slidable through the ratchet-wheel, and means operated during the reciprocation of the rod to advance the ratchet-wheel to rotate the rod.
  • a traverse-rod for winding and like machines provided with a continuous helical formation on its periphery having a diiferential lead with its pitch gradually decreasing along the length of the rod.
