A manufacturing apparatus for an optical fiber tape core wire, the manufacturing apparatus manufacturing the optical fiber tape core wire including a plurality of single-core coated optical fibers while moving the plurality of single-core coated optical fibers from upstream to downstream, the plurality of single-core coated optical fibers being partially coupled to each other, the manufacturing apparatus comprising:
- a coating part that coats the plurality of single-core coated optical fibers with a resin in an uncured state, the plurality of single-core coated optical fibers being disposed in parallel;
- a removal part that partially removes the resin in the uncured state between, among the plurality of single-core coated optical fibers coated with the resin in the uncured state and disposed in parallel, a pair of the plurality of single-core coated optical fibers, the pair of the plurality of single-core coated optical fibers being adjacent to each other;
- and
- a curing part that cures the resin in the uncured state remaining on the plurality of single-core coated optical fibers, wherein:
- the removal part includes:
- a plurality of rotary blades each of which is disposed so as to be located between the pair of the plurality of single-core coated optical fibers adjacent to each other and intermittently extrudes the resin in the uncured state between the pair of the plurality of single-core coated optical fibers adjacent to each other;
- a positioning part including:
- a through-hole through which the plurality of single-core coated optical fibers coated with the resin in the uncured state passes;
- a plurality of slits each communicating with the through-hole, the plurality of slits being a plurality of slits inside which the plurality of rotary blades rotates, respectively;
- and
- a plurality of outlet openings of the plurality of slits, the plurality of outlet openings being a plurality of outlet openings through which the resin extruded by the plurality of rotary blades comes out;
- and
- a suction part including a suction opening, the suction opening being disposed so as to cover the plurality of outlet openings,
- the plurality of outlet openings opens to a downstream-side end portion of the positioning part, the downstream-side end portion of the positioning part being an end portion of the positioning part on a downstream side of a moving direction of the plurality of single-core coated optical fibers,
- a downstream-side end portion of the suction opening is disposed on a downstream side of downstream-side end portions of the plurality of outlet openings and the downstream-side end portion of the positioning part, and
- in the removal part, the resin in the uncured state between the pair of the plurality of single-core coated optical fibers adjacent to each other is intermittently extruded to the plurality of outlet openings by rotating the plurality of rotary blades while moving the plurality of single-core coated optical fibers coated with the resin in the uncured state from upstream to downstream in the through-hole, and the resin in the uncured state extruded through the plurality of outlet openings is suctioned by the suction part.
