ABSTRACT:
The first-state jacketed roller in an apparatus for spin drawing synthetic fiber comprises a roller rotatably mounted on a shaft and encompassing a fixed, non-rotatable inner core. The roller includes an electrically conductive tubular member coaxial with, and hermetically affixed to, the inner wall of the roller. A plurality of bore holes extend in the conductive member parallel to the roller axis and are coextensive therewith, and a heat transfer fluid fills each bore hole. The fluid divides into a liquid and a vapor phase when the roller is heated and rotation of the roller forces the liquid phase outwardly under centrifugal force into engagement with the outer portion of each bore hole.
