Abstract: A LARGE NUMBER OF LIGHT-TRANSMITTING CONVENTIONALLY CLAD GLASS RODS ENVELOPED OR SUPERCLADDED WITH A BONDIING MATERIAL ARE GATHERED, ALIGNED, HEATED AND STRETCHED WHILE MAINTAINED IN ALIGMENT TO REDUCE THEIR DIAMETER AND BOND THEM TO EACH OTHER TO FORM A BUNDLE OF MUTUALLY ALIGNED FIBERS. THE MATERIAL FOR THE LIGHT-TRANSMITTING RODS IS SELECTED SO THAT IT WITHSTANDS A CHEMICAL SOLUTION IN WHICH THE BONDING MATERIAL IS SOLUBLE. INTERMEDIATE PORTIONS OF THE ROD ARE IMMERSED IN THE SOLUTION TO DISSOLVE THE BONDING MATERIAL FROM BETWEEN THE INDIVIDUAL FIBERS WHILE THE ENDS OF THE FIBERS REMAINS EMBEDDED THEREIN, FIXED WITH RESPECT TO EACH OTHER AND IN THEIR ORIGINAL, MUTUALLY ALIGNED POSITION.
