ABSTRACT:
In the disclosed process, a multiplicity of like fibers of fusible material are arranged in a bundle which is brought to the drawing temperature. The bundle is drawn to reduce its cross sectional area while retaining its cross sectional configuration. During the drawing step, a fluid pressure is maintained in the peripheral rows of fibers which exceeds that of the remaining fibers of the bundle to maintain a substantially uniform diameter of the fiber elements in the resulting drawn fiber bundle.
