<p>Method of reinforcing and/or decorating the blades of diving fins comprising the the steps of insertion into the thermoplastic forming the fin blade of laminar inserts of materials having mechanical and/or chromatic and decorative characteristics differing from those of the material of the blade itself. This insertion Lakes place during the moulding of the fin blade, by incorporation of these inserts into the mass of material forming the said blade. The said inserts comprise a base plate of a thermoplastic compatible with the material of the fin blade, to which the laminar insert of heterogeneous material is applied, the whole then being covered by a second plate of material compatible with the material of the fin blade, and the resulting composite part being inserted into the fin blade mould in such a way as to incorporate it into and weld it to the mass of material forming the blade in the moulding process. Advantageously, the said laminar inserts are positioned inside the fin blade mould, the blade being overmoulded around the said inserts.</p> |
