  • Methods for making a fiber optic display device
    Patent number: 3989493
    Abstract: A display device is formed from a fiber optic bundle by stripping a portion of the sheath from the bundle and thereafter twisting the exposed fibers together, heating the fibers to form a permanent bend therein and then applying a shock to the fibers to untwist the same. In an alternative method, the stripped fibers are spread into a desired pattern by an oscillating pin and an adhesive applied thereto to retain the fibers in the pattern formed by the pin.
