1. Process for producing in a mould (13) a ski core (8; 118; 24) of injected or moulded cellular synthetic material, wherein the synthetic material is expanded a round a hollow tubular structure (5, 105) extending longitudinally and formed by at least one tube (6, 7; 106, 107), characterized by the fact that the ends (6a, 6b; 7a, 7b) of said tube are closed before the injection or moulding operation so that on its expansion the synthetic material cannot penetrate into the interior of said tube (6, 7; 106, 107). |
