Abstract: A method and apparatus for manufacturing an arched metallic profile, in a continuous in-line process. The method comprises forming the metallic profile; and arching the formed metallic profile in a continuous in-line process. The apparatus includes a roll forming station configured to receive flat metallic composition and output a given profile. An arching device is configured to receive the metallic profile and bend the metallic profile having a desired radius of curvature wherein a portion of the arching device is displaced with respect to said roll forming station vertically and/or horizontally.

Abstract: An optical stack includes an intrinsic polarizer, such as a K-type or thin KE polarizer sheet. Optically functional coatings are disposed on one or both of the surfaces of the intrinsic polarizer. The optically functional coatings include a hardcoat, a transflector coating, a reflector coating, an antireflection film, a liquid crystal polymer retarder coating, a diffusion coating, an antiglare film, a wide view film, and an electrode. An optical stack including an intrinsic polarizer and an optically functional coating may have a thickness of less than 25 microns.
