PROBLEM TO BE SOLVED: To provide a device comprising multiple godet rollers, which are arranged inside a godet roller box, pull out and extend newly spun multiple yarns and consume as little energy as possible by heating, extending and relaxing yarns as evenly as possible.SOLUTION: A device can ensure uniform quality and manufacture completely stretched polymer yarn with qualitatively quite high value due to appropriate means 10.1, 10.2, 10.3 for leading accompanying air, which is generated by rotation of godet rollers 1.2 to 1.4 and may disturb the running of yarn, to a dead zone 16 of the godet roller box 4.SELECTED DRAWING: Figure 1 |
