ABSTRACT:
A method of producing skis of the type comprising a core of a lightweight material, e.g., lightweight wood, where layers of fiber-reinforced plastic, e.g., fiberglass-reinforced polyester, are provided on the top and bottom sides of the finished ski. A sole of a plastic material is glued to the lower fiber reinforced plastic layer. The sides of the core are covered with a protective layer of a plastic material, e.g., a hard polyurethane foam or a thermoplastic, for example, ABS (acrylic butadiene-styrene), which has been molded to the core in a mold. The core is placed near the top layer of fiber-reinforced plastic and at a distance from the lower layer of fiber-reinforced plastic. The space between the lower side of the core and the lower layer is formed and molded at the same time as the side edges are molded on.
