Introduced into a mould (4) partly filled with a first ingredient (A) in a liquid state is a core (8) of elastomeric material forcing the ingredient to fill one or more moulding hollow spaces (9). The first ingredient (A) is frozen after the core (8) has been drawn out of the mould (4) to enable filling up of the latter with at least one second ingredient (B). The different colours of the first and second ingredients (A, B) will simultaneously appear on the outer surfaces of the final product (16). |
