Method and device for manufacturing optical fiber ribbon
A method for manufacturing an optical fiber ribbon where adjacent optical fibers are intermittently connected in a length direction includes: feeding the optical fibers along the length direction; and intermittently applying a resin in the length direction by: rotating, between adjacent ones of the optical fibers, a rotating member having a recess, and blocking the resin with a peripheral edge part of the rotating member where the recess is not formed. A moving speed, in the length direction, of the peripheral edge part at a position where the peripheral edge part blocks the resin between the optical fibers is slower than a feeding speed of the optical fibers.
1. A method for manufacturing an optical fiber ribbon where adjacent optical fibers are intermittently connected in a length direction, the method comprising:
feeding the optical fibers along the length direction;
intermittently applying a resin in the length direction by:
rotating, between adjacent ones of the optical fibers, a rotating member having a recess, and
blocking the resin with a peripheral edge part of the rotating member where the recess is not formed; and
increasing strength of a connection part formed by the resin applied to the optical fibers by setting a moving speed, in the length direction, of the peripheral edge part at a position where the peripheral edge part blocks the resin between the optical fibers, to be slower than a feeding speed of the optical fibers.
2. An optical fiber ribbon manufacturing device that manufactures an optical fiber ribbon according to the method as set forth in claim 1 .
3. The method according to claim 1 , wherein the feeding speed of the optical fibers is at least 2.9 times the moving speed, in the length direction, of the peripheral edge part that is caused by rotation of the rotating member at the position where the resin is blocked between the optical fibers.
4. An optical fiber ribbon manufacturing device that manufactures an optical fiber ribbon according to the method as set forth in claim 3 .
5. The method according to claim 3 , wherein the feeding speed of the optical fibers is at most 35.1 times the moving speed, in the length direction, of the peripheral edge part that is caused by rotation of the rotating member at the position where the resin is blocked between the optical fibers.

7. A method for manufacturing an optical fiber ribbon where adjacent optical fibers are intermittently connected in a length direction, the method comprising:
feeding the optical fibers along the length direction;
intermittently applying a resin in the length direction by:
rotating, between adjacent ones of the optical fibers, a rotating member having a recess, and
blocking the resin with a peripheral edge part of the rotating member where the recess is not formed; and
controlling a thickness of the resin applied to the optical fibers by setting a moving speed, in the length direction, of the peripheral edge part at a position where the peripheral edge part blocks the resin between the optical fibers, to be slower than a feeding speed of the optical fibers.
