Abstract
A louver laminated with a very thin film (i.e. a transfer film, very thin layer, etc . . . ) for use in the construction of window blinds such as Venetian blinds, and the like, the louver having opposed top and bottom surfaces, as well as opposed first and second side surfaces each laminated with a very thin film. More particularly, the film is so thin, that the boundary edges of the film, once laminated to a surface of the louver, are imperceptible to human touch, i.e. they are tactilely invisible. An apparatus and method for making a louver laminated with a very thin film is further proposed.
