Patent ID: 8728360

Claim:
An apparatus for producing optical sheeting, comprising: a first rotating roll configured to be heated; a second rotating roll; a first belt mold that has molds for optical elements on a surface thereof, is mounted around the first rotating roll and the second rotating roll, and is configured to turn around the first rotating roll and the second rotating roll with rotation of the first rotating roll and the second rotating roll; a sheet feeder that feeds synthetic resin sheeting onto a surface of the first belt mold; a second belt mold that has molds for optical elements on a surface thereof, and is configured to be pressed against the first belt mold at a portion of an area where the first rotating roll and the first belt mold are in contact with each other and to turn with the turning of the first belt mold; and at least two pressure rolls around which the second belt mold is mounted and which is configured to press the second belt mold against the first belt mold, wherein one of the pressure rolls is arranged at a position where the second belt mold comes away from the first belt mold and is configured to be cooled at a surface thereof with a cooling medium, the second belt mold is cooled at a portion where the second belt mold comes away from the first belt mold, at least one of the pressure rolls other than the pressure roll that is cooled at the surface thereof is heated at a surface thereof, one of the pressure rolls that are heated at the surface thereof is arranged at a position where the first belt mold and the second belt mold come close to each other, and the second belt mold is heated at least at a portion where the second belt mold comes close to the first belt mold, wherein at a position where the film is subjected to peeling, one side of the film is heated while the other side of the film is cooled.
