Method of producing a complex moulded structure, in particular ski and complex moulded structure so obtained

Abstract

Abstract This method which consists:   - in depositing a first element (8, 9) in a mould (1, 2);   - in depositing a second element (11, 12) in this mould;   - in closing the mould;   - then in injecting, between these two elements, reagents intended to react in order to form a foam which expands in situ;   - then in cooling the contents of the mould;   - and, finally, in opening the mould in order to remove the complex structure, is characterised:   - in that two flexible membranes (10, 10a) made from plastic material, forming a sheath upon closure of the mould, are inserted between the first and the second assembly;   - and in that the reagents of the foam are injected into the said sheath (10), which stretches until it presses the elements against the walls of the mould (1, 2). <IMAGE>
