<p>This invention provides a traverse device wherein the dimensions of portions up to a thread-dividing fulcrum guide and a godet roller, which are disposed on the upstream side of a racking fulcrum guide, are decreased to facilitate the thread setting operation, the dimension of a machine base is decreased as a whole to simplify the structure to thereby shorten the times for working and assembling, high selveges and ribbons, which occur during packaging, are decreased and a turnback position of the thread can be easily changed. A straight line for connecting a traverse end portion (A) in a traverse unit (6 - 1) to a traverse end portion (B) and an axis of a touch roller are not arranged in parallel to each other so that the traverse unit (6 - 1) disposed at least at one end can be displaced to the side of a traverse unit (6 - 4) disposed at the other end, and the traverse unit (6 - 1) is of such an arrangement that three vanes (15 - 1 to 15 - 3) are fastened to a first rotor (13) and two vanes (20 - 1 to 20 - 2) are fastened to a second rotor (18) in such a manner that the respective vanes are arranged at equidistant positions on the rotating planes, respective positions of rotary centers of the first rotor (13) and the second rotor (18) are set such that the angle of rotation of the rotor rotating during the time when one vane comes into contact with a thread, moves the thread along a guide (23) for tension thread guard and then leaves the thread, is set at 60 DEG for the first rotor (13) and set at substantially 90 DEG for the second rotor (18), and the ratio in rotation speeds of the first rotor (13) to the second rotor (18) is set at 2:3. <IMAGE></p> |
