<p>A member 2 for supporting glass filaments 1 in an apparatus for fabricating glass fibers (primary filaments being formed from molten glass and then further attenuated to fibres by hot gaseous blasts 5) comprises a pair of glass filament bearing surfaces 11, 15 of the same structure symmetrically formed at both sides of the member 2 and is so rotatably supported in the apparatus as to selectively bear the glass filaments on either bearing surface 11 or 15, and further includes at least three lateral angular edges (16, 17 & 18 and 19, 20 & 21) formed on each of the surfaces (11 and 15 respectively) for simultaneously making contact with each of the glass filaments 1. Since the filaments can be supported by a new but identical glass filament bearing surface merely by rotating the member through 180 DEG without stopping the overall apparatus, when the present glass filament bearing surface is worn, thereby to double the operating time of the member, this apparatus can eliminate the decrease of the productivity by the stoppage of the apparatus and wasteful loss of the glass stock to thus improve the production of the glass fiber as much. <IMAGE></p> |
