Godet roll

Godet roll go- det- n. Roll used for transporting and controlling the movement of bundles of fibers and yarns in the processing of these materials. 

As the melt emerges from the spinneret hole, it passes down a spin chimney where it is cooled or quenched in a streamline air flow operating at a controlled temperature. Towards the exit of the spin chimney, the multiple fibers converge into a multifilament bundle or yam and are hauled offby godet rolls. 

The monofilament process (Fig. 8.13) includes aspects of both the melt spinning and slit film processes. The extmder is equipped with a melt pump immediately upstream of a spinneret that extmdes relatively thick filaments ranging from 0.08 mm to 3.0 mm in diameter. The filaments are quenched in a water bath and are hauled offby godet rolls. Orientation is performed by reheating and stretching in an oven under tension applied by a second haul-off. An alternative orientation process uses heated godet rolls in place of the oven.
