Manufacturing method of optical fiber ribbon, manufacturing device for optical fiber ribbon implementing said manufacturing method, and optical fiber ribbon manufactured with said manufacturing method

A manufacturing method for an optical fiber ribbon, in which:

• a plurality of optical fiber core cables are arranged in parallel and the neighboring optical fiber core cables are partially coupled with each other at given intervals in a longitudinal direction to form a subunit;
• and the optical fiber core cables positioned at side edges of the neighboring subunits are partially coupled with each other at a given intervals in the longitudinal direction, comprises:
• a resin applying step for sending out the plurality of the optical fiber core cables in a parallel manner with intervals provided therebetween, in the longitudinal direction of the optical fiber core cables, applying an uncured resin to the plurality of the optical fiber core cables, moving a plurality of interrupt members which are arranged corresponding to positions between each of the optical fiber core cables to interrupt the uncured resin, and continuously changing positions at which the uncured resin is interrupted and positions at which the uncured resin is ejected without interruption by the interrupt members;
• and
• a resin curing step for irradiating positions, at which the plurality of the optical fiber core cables are arranged in parallel, concentrated and in contact with each other, with resin curing energy required for the uncured resin coated on the optical fiber core cables to cure, thereby forming coupled portions at which the optical fiber core cables are coupled to each other,
• wherein a moving period or phase of the interrupt members is changed for every arbitrary optical fiber core cables.
