PURPOSE:To obtain a tapelike optical fiber with improved stress by flatly drawing out plural optical fibers, coating a resin composition which cures under ultraviolet rays or infrared rays on parts close to the adjoining surfaces, and curing the composition to unite the fibers to one body. CONSTITUTION:Plural optical fibers 1 each having a primary coating are supplied and arranged flatly with an arranging device 2. A resin composition which reacts and cures under ultraviolet rays or electron beams is coated on the fibers 1 with a resin coater 3, and after curing the composition with an ultraviolet-ray or electron-beam irradiator 4, the resulting tapelike optical fiber is coiled with a coiler 5. Tapelike optical fibers having different cross-sectional structures can be manufactured by changing the shape of the coater 3. For example, when the resin composition is dropped onto the contact surfaces of arranged optical fibers and cured under ultraviolet rays, a tapelike optical fiber having a cross-sectional structure shown by figure (a) can be obtd. |
