Abstract
A fiber drawing process and apparatus in which the fibers are drawn in small increments by passing the fibers in multiple wraps over on rotatably mounted spaced apart spindles having discrete circumferential microterraced surfaces which support the fiber. The terraced sufaces are parallel to the axis of rotation of the spindles and each microterraced surface having a continually increasing radius. The number of microterraces is equal to or less than the number of wraps of the fiber about the spindle. Cylindrical rolls in tandem with the microterraced spindles permit fine adjustments of the draw ratios.
