1. A method of manufacturing a final assembly comprising at least one layer made up of N′>1 helically wound metal filamentary elements, the method comprising:
a step of supplying a transitory assembly comprising at least one layer made up of M′>1 metal filamentary elements helically wound around a transitory core; and
a step of separating the transitory assembly into at least:
a first split assembly comprising at least one layer made up of M1′>1 helically wound metal filamentary elements, the M1′ metal filamentary element originating from the layer made up of M′>1 metal filamentary elements of the transitory assembly,
a second split assembly comprising at least one layer made up of M2′>1 helically wound metal filamentary elements, the M2′ metal filamentary elements originating from the layer made up of M′>1 metal filamentary elements of the transitory assembly, and
the transitory core or one or more ensembles comprising the transitory core; and
a step of reassembling at least the first split assembly with the second split assembly to form the layer made up of N′ helically wound metal filamentary elements,
wherein the separation step and the reassembly step are performed such that M1′+M2′<M′.
