<p>An optical fiber drawing apparatus which includes a heating furnace (3A) which fuses a forward end of an optical fiber preform (1) for drawing an optical fiber (10), and a screening portion (7A) which applies tension to the optical fiber (10) through in-line processing, for guarantee of its strength. The screening portion (7A) further includes a suction device (S), disposed along a passage of the optical fiber (10) running through it, for sucking in the optical fiber (10).</p> |
