Abstract
A machine and method for obtaining a curved surface of a film structure that comprises a carrier layer and a functional film (). The machine comprises an annular support member having a supporting face adapted for supporting the film structure, and an opening () that is covered by the film structure when said film structure is supported by the annular support member; a clamping system configured to clamp the annular support member and the film structure when supported by the annular support member; and a forming system configured to apply pressure, and preferably temperature, on the film structure so as to curve said film structure in or through the opening () of the annular support member. The opening () of the annular support member has a contour that is non-circular so that the obtained curvature of the functional film () corresponds to a target curvature.
