ABSTRACT:
A method and apparatus are provided for aligning individual fibers parallel to the main fluid stream that is conveying them, using fluid-dynamic forces. This method and apparatus are based on the use of converging streamlines in a nearly irrotational flow to provide the necessary moments to rotate the fibers so that they become parallel to the streamlines. Counterflow jets are provided to create the desired streamline behavior in a main fluid stream. The irrotationality of the flow and the nearly parallel streamlines thus prevent further fiber rotation downstream.
