Abstract
The method comprises the stages of: preparing a metal matrix (12) which reproduces in positive form the shape of at least one ornament (10), forming a first hollow vessel, the bottom of which is constituted by the metal matrix (12), pouring a rubber (16) in the fluid state into the first vessel and leaving it to harden to give a matrix (18) of hardened rubber which reproduces in negative form the shape of at least one ornament (10), this operation being repeated several times, putting together the matrices (18) of hardened rubber in a side-by-side arrangement to give a composite structure (20), forming a second hollow vessel, the bottom of which is constituted by the composite structure (20), pouring a resin (24) into the second vessel and leaving it to harden to give an intermediate multimatrix (26), forming a third hollow vessel, the bottom of which is constituted by the intermediate multimatrix (26), and pouring a rubber (30) in the fluid state into the third vessel and leaving it to harden to give a rubber multimatrix (32) having several identical figures (34) into which is then poured a decorative resin (36) which forms the individual ornaments (10).
