| 摘要 |
The present invention concerns an adjustable shroud useful with any melt spinable polymers during their production. The adjustable shroud can be produced from different embodiments such as hinged wall sections, bellows, or collapsible or nesting walls. The adjustable shroud may be controlled by means of hydraulics, pneumatics, mechanical worm screws powered by an electrical motor or manually, or any other suitable means obvious to those skilled in the art. The length of the adjustable shroud functions such that it extends toward or away from the spinneret depending on the desired length of the shroud.
