Abstract

L'invention concerne un procédé de fabrication d'un masque. Ce procédé consiste à realiser dans un matériau filtrant un flan en deux parties, à former par pliage deux lèvres sur les extrémités opposées dudit flan, à replier l'une sur l'autre les deux parties du flan et à les fixer, à leur périphérie, à l'exception de la partie devant constituer l'ouverture du masque. L'invention s'applique notamment au filtrage de l'air respiré par l'utilisateur.
