MERGING APPARATUS FOR MANUFACTURING OPTICAL LAMINATED FILM, APPARATUS FOR MANUFACTURING OPTICAL LAMINATED FILM, AND VANE MEMBER

摘要

PROBLEM TO BE SOLVED: To improve uniformity of a layer thickness.SOLUTION: A merging apparatus for manufacturing an optical laminated film includes a vane member 14 having a V-shaped portion 14b which includes a first side face 14c constituting a part of first resin flow channels (11 and 11b) and a second side face 14d constituting a part of second resin flow channels (12 and 12c) that are arranged in substantially V shapes in the vicinity of merging portions (11c and 12f) between the first resin flow channels and the second resin flow channels. A ridge part 14e in which the first side face and the second side face of the vane member cross has a curved shape (substantially arc shape and the like) so as to be recessed or project.
