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.
