A mesh () is placed around a bundle () of fused glass fibers. The bundle is then immersed in a leaching bath (). The ends of the bundle are protected from the bath fluid by furrules (). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

Method of manufacturing a leached fiber bundle

The method for detecting faults in transparent material includes irradiating a definite partial volume in the material with a first radiation source and coupling light into the material from a second source so that its optical path in the partial volume extends in the interior of the material. A fault in the partial volume is detected by light scattering, bright field absorption, and/or deflection of light of the first radiation source by the fault. The apparatus for detecting faults includes a first radiation source for illuminating a definite partial volume of the material, a detector for detecting light from this partial volume, and a second radiation source. The second radiation source is arranged in relation to the material so that the associated optical path in the partial volume passes exclusively in the interior of the material.

To detect defects in a continuously moving strip of transparent material, especially a wide thin glass strip, a narrow monochromatic light beam is guided transverse to the motion direction of the moving strip and is coupled into the moving strip, preferably through an edge region of the moving strip, by a transparent liquid arranged between the moving strip and the light source producing the monochromatic light beam. In a first embodiment the monochromatic light beam is inclined to an upper surface of the moving strip through which it passes and is coupled into the moving strip by a transparent liquid whose index of refraction is greater than that of the atmosphere surrounding the moving strip. In a second embodiment the monochromatic light beam is parallel to the upper surface of the strip and is coupled into an edge surface of the continuously moving strip by a transparent liquid whose index of refraction is about equal to that of the moving material. In the first embodiment the light guide system for the light beam includes a prism, whose light outlet surface is parallel to the upper surface of the glass strip. The transparent liquid is arranged between the prism and the glass strip, which is supported on rolls.
