ABSTRACT:
A method of uniformly breaking glass fibers in a bundle of fibers in which the apex of a cone is inserted into the end of the bundle. The fibers in the bundle are distributed in a single plane about the surface of the cone with the free ends of the fibers extending beyond the base of the cone. A sleeve on the bundle is shifted forwardly toward the base of the cone to firmly grip the fibers therebetween. The outer surfaces of the fibers are then scratched and a compressive force is exerted to the free end of the fiber bundle to cause the fibers to bend and break at the base of the cone.
