Abstract:
1. A molding machine for manufacturing an optical film, comprising: a hopper contoured to provide a raw material of the optical film and defining a narrow outlet; a first cylindrical roller rotatable about a first central axis of the first cylindrical roller; a second cylindrical roller rotatable about a second central axis of the second roller, wherein the first central axis is in parallel with the second central axis; the first and second cylindrical rollers are located at two opposite sides of the narrow outlet and positioned at substantially a same height below the narrow outlet, wherein a gap between the first and second cylindrical rollers allows the raw material to pass through the gap; an ultraviolet (UV) light source located in the second cylindrical roller, wherein an emission direction of the ultraviolet light source is orientated toward a space between the narrow outlet and the second cylindrical roller; and a holder contoured to hold the second cylindrical roller, the holder comprising: at least one fixing unit connecting the central shaft and the two rotatable shafts.
