摘要

The active part of the mask has a succession of bosses and of hollows. An Independent claim is included for the method of producing the skin. The mold shell (6) is heated. The active part (10) of the mask is positioned, facing the shell. Plastic material is brought into contact with the hot shell, to gel the skin. The active part of the mask is separated from the shell. A second stage of skin gelling is undertaken.
