Method for the manufacture of a curved face laminated reflector (1 to 6) which reflects radiation energy and in particular solar energy. According to the method, a first adhesive layer (4) penetrable by radiation and hardened by heat, a combination film (5, 6) consisting of a flexible core layer (5) and of a reflecting thin metal layer (6) deposited onto the said core layer, and a second adhesive layer (3) penetrable by radiation and hardened by heat are sandwiched, one upon the other, between two support layers (1, 2) of the desired curved form so that the edges of the combination film (5, 6) extend at the maximum to the level of the edges of the adhesive layers (3, 4). The laminate (1 to 6) produced in this way is subjected to a compression and heat treatment so that, when the combination film (5, 6) shrinks to some extent, the adhesive layers (3, 4) melt together around the edges of the combination film (5, 6) and completely enclose the combination film (5, 6) in a hermetical manner, which, among other things, substantially improves the weather resistance of the reflector. |
