Screening apparatus for optical fiber

A screening apparatus for an optical fiber comprising:

• a delivery bobbin that delivers an optical fiber;
• a screener that applies tension to the delivered optical fiber to perform screening of the optical fiber;
• a winding bobbin that winds the optical fiber after the screening;
• and
• a static electricity remover that removes static electricity of the optical fiber traveling on a predetermined passage of the optical fiber, the static electricity remover being disposed along the predetermined passage from an exit side of the screener to an entry side of the winding bobbin, wherein
• the predetermined passage is one of a plurality of passages, which are provided between two pulleys,
• the static electricity remover removes static electricity of the predetermined passage, and
• the predetermined passage among the plurality of passages satisfies the following conditions:
• 1) a distance of the predetermined passage is ensured for removing static electricity from the optical fiber after the screening by the static electricity remover;
• 2) the distance of the predetermined passage does not change and is stable;
• and
• 3) the predetermined passage is arranged closer to the winding bobbin than at least one of the rest of the plurality of passages.
