Abstract (en)
A core (1) for winding reels, particularly for reels of paper, cardboard, polymeric materials and the like, which is substantially constituted by a tubular element (2) comprising a plurality of strips (3) wound helically, at least partially overlapped and mutually associated. The strips (3) are made of a material chosen from paper, cardboard, polymeric materials and the like. At least one of the strips (3), arranged in proximity to the outer surface of the tubular element (2), is impregnated with a substance that is adapted to confer a high level of water-repellence to the at least one strip (3a).
