PROBLEM TO BE SOLVED: To provide a manufacturing apparatus and a manufacturing method of an intermittent optical fiber ribbon which is easy to separate and easy to handle when being twisted and bent, by only making a cut in the optical fiber ribbon.SOLUTION: The manufacturing apparatus includes a cutting device 200 which makes intermittent cuts in a common coating in the longitudinal direction between plural stings of neighboring optical fiber core wires aligned in a state of being in contact with each other and outer surfaces of which being integrated by the common coating. The cutting device 200 includes: a plurality of circular blades 10, 10' each having a cutting blade on a part of the outer periphery thereof and a shaft-direction thickness of an integer multiple of an outer diameter of the optical fiber core wire at a shaft insertion part; and two parallel rotation shafts 20, 20'. The plurality of circular blades 10, 10' are arranged next to each other on the respective rotation shafts 20, 20 so that the cutting blades of the plurality of circular blades 10, 10' oppose to each other. An optical fiber ribbon 100' is inserted between the plurality of opposing cutting blades.SELECTED DRAWING: Figure 3 【課題】テープ心線に切れ込みを入れるだけで、分離し易く、捻ったり曲げたりするのに取り扱い易い間欠光ファイバテープ心線の製造装置および製造方法を提供する。【解決手段】互いに接する状態で並列させた複数本の光ファイバ心線の外面を、共通被覆により一体化させたテープ心線に対して、隣接する光ファイバ心線間の共通被覆の長手方向に間欠的な切込みを入れる切断装置２００を備える。切断装置２００は、外周の一部に切刃を設けた円盤状の丸刃１０、１０'であって軸挿通部の軸方向の厚みが光ファイバ心線の外径の整数倍の厚みを有する複数の丸刃１０、１０'と、平行な２本の回転軸２０、２０'を備え、２本の回転軸２０、２０'のそれぞれに、複数の丸刃１０、１０'の切刃を対向させて隣接配置している。複数の対向する切刃間に光ファイバテープ心線１００'が挿通される。【選択図】図３
