A method and apparatus for continuous drawing of fibers in the form of
coiled fiber loops (e.g., polygonal or serpentine loops). The successive
fiber loops are continuously laid on receiving ends of a plurality of
conveyer-drawing members (CDM) [e.g., rotating threaded spindles (54) or
circulating endless chains (80) and (108)] disposed about a central axis
and diverged from this axis. Coiled fiber loops are conveyed along the
central axis and simultaneously drawn by enlarging a circumference of the
fiber loops by the CDM. The leading fiber loops are continuously taken
off at delivery ends of the CDM and conveyed from the drawing apparatus
at an outlet speed. Heat chambers (11) and (148) envelop at least the
most part of CDM. The process can operate at low drawing speed and long
drawing time typical for lab-scale experiments and equal or higher outlet
speed and throughput typical for commercial drawing processes. The method
can produce low-cost/high-strength/high-modulus/low-shrinkage commercial
polymer fibers.
