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.

Abstract: In a textile draw warping system having independently driven sets of draw rolls and an independently driven warp beam, synchronous braking of the driven components is controlled by individual pneumatic brakes at each driven component operated by a central programmable logic control system to brake the driven components at respective rates of deceleration preset to maintain constant speed ratios between the driven components during braking. Auxiliary control of dynamic braking and driving of the several drive motors corrects deviations in the driven components' predetermined rates of deceleration.
