<p>Fiberizing bushing assemblies (26), usually of rectangular shape, for fiberizing molten inorganic material like glass require cooling members located in the proximity of the orifices or tips forming the fibers. Cooling tubes (16) carrying a cooling fluid like water are used by some fiber manufacturers and the cooling tubes have always been oriented with the length dimension of the bushing. It has now been discovered that orienting the cooling tubes (54) to be substantially parallel to the width dimension, though more costly to fabricate because of the greater number required per bushing assembly, significantly reduce fiber break out rate and significantly increase productivity because they are easier to keep properly adjusted and result in a more uniform temperature of the fiberizing tips (12,52).</p> |
