Abstract
An optical fiber coating apparatus which has a left holder unit 13a and a right holder unit 13b, in the left holding space 12a and right holding space 12b defined in those units are housed a second layer die 16a, 16b, a first layer die 17a, 17b, and a nipple 18a, 18b in a superposed state. The second layer die 16a, 16b and the first layer die 17a, 17b and the nipple 18a, 18b have block shaped planar outer contour shapes and the holding space 12a, 12b housing these also has a block shaped planar outer contour shape. Since the outer shapes of the dies 16a, 16b and 17a, 17b and the nipple 18a, 18b and the holding space 12a, 12b are all block shaped, it is easy to perform the axial alignment of the holes 30, 31, and 32 through which the optical fiber passes by pressing the die 16a, 16b, the die 17a, 17b, and the nipple 18a, 18b against the reference surfaces 19, 21 of the left holding space 12a.
