Abstract: A modular panel to make a roof or a wall of a building comprises an external shell and an internal shell, made of moldable plastic material, coupled with each other to define at least a compartment. The panel integrates in itself means for the capturing and irradiation of energy, and relative energy accumulation means, the capturing and irradiation means being associated, at least partly, with the external shell.

Abstract: Structure, such as a roof or a wall, comprising a plurality of modular panels (11). Each modular panel (11) has a shell (13) and a filling element (14) coupled with each other and defining at least a compartment (24, 25) for the disposition of a heat-carrying fluid and/or of fluidic and electric connection cables. Connection means are provided between one modular panel (11) and one or more adjacent modular panels (11).

Abstract: Apparatus and method to replace a feed reel for feeding a film and to lay and cut a segment of the film. The apparatus includes a work plane, laying device having its own first gripper, a cutter having its own second gripper, and an unwinding assembly associated with the feed reel. The unwinding assembly includes a guide able to keep the end of the film guided during its insertion into the first gripper of the laying means and the cutting means, a third gripper able to be selectively activated during the change-of-reel step, and a tensioner able to keep the segment of film in tension between the feed reel and the first and second grippers and to allow the recovery of the segment of film during the change-of-reel step without needing to rewind the feed reel.

Abstract: Method and device to produce polyurethane articles covered on one side by a film. The method provides a step wherein the film is made to adhere to one zone of a part of a mold, and a heating step wherein one segment of the film is heated before the film is made to adhere to the part of the mold. The heating step is performed, by means of a movable heating assembly, in an intermediate position between a first position outside the mold and a second position associated with the mold. In the heating step the film is also partly pre-formed.

Abstract: 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).
