摘要:
This sheet manufacturing apparatus is provided with: a nozzle (101) for extruding a heated resin sheet (110); a main roll (130) with a surface on which microstructures are formed; a follower roll (140) disposed at a distance from the main roll (130); and an electricity-supplying mechanism (150). The electricity-supplying mechanism (150) heats an electrically conductive section (131a) of the main roll (130) by supplying electricity to the electrically conductive section (131a) from both edges of the main roll (130).

摘要:
This manufacturing device is provided with a first roller (230) and a second roller (240) for molding an uneven-thickness film. The first roller (230) is provided with a truncated-cone-shaped portion (234) and a disc-shaped portion (232), the diameter of the disc-shaped portion (232) is larger than the diameter of a large-diameter face (234b) of the truncated-cone-shaped portion (234), and the second roller (240) is provided with a column-shaped portion. A thick part is formed in a molded body of the uneven-thickness film between the truncated-cone-shaped portion (234) of the first roller (230) and the column-shaped portion of the second roller (240), and a thin connecting part is formed in the molded body between the disc-shaped portion (232) of the first roller (230) and the column-shaped portion of the second roller (240).
