    摘要: A method of making a lens array includes a first step of forming a resin-molded piece, a second step of applying a coating to the resin-molded piece, a third step of melting the applied coating and a fourth step of solidifying the melted coating. The resin-molded piece formed in the first step includes a plurality of lenses each having a convex lens surface, and a holder portion for holding the plurality of lenses. In the second step, the coating is applied to the holder portion so as to surround each lens surface.

    摘要: Device to produce polyurethane articles (37) covered by a film (19), including a mold (30) comprising a female part (13) and a male part (12) defining a molding cavity (18) inside which polyurethane material (24) is able to be injected. The device also comprises, in association with the perimeter edge of said female part (13), means able to exert a connection function in substantial cooperation with the zone of discontinuity between said female part (13) and said male part (12). The means comprise a movable annular ring-nut (22) including a first position (22a) to load a segment of said film (19) in order to insert said segment inside the mold, and a second position (22b) at least partly overlapping on the perimeter of said female part (13) in order to cooperate with said female part (13) during the molding of said polyurethane material (24).
