A respiratory mask comprises a body portion that is formed from an air- permeable material and that has at least one component, for example an exhalation valve, secured to the body portion by a printed patch of adhesive. In one embodiment, the mask is a fold-flat mask (1) comprising panels (3, 5, 7) each of which is formed from superposed layers of air-permeable material. An exhalation valve (13) is secured to the centre panel (3) by a patch of adhesive that is printed on the outer layer of the panel. Use of a printed patch of adhesive enables components to be accurately secured to the mask body at high speeds.
L'invention concerne un masque respiratoire qui comprend un corps formé à partir d'une matière perméable à l'air et qui comporte au moins un composant, par exemple une valve expiratoire, fixé au corps par une pastille adhésive imprimée. Selon une variante, le masque est un masque (1) qui se replie à plat et qui comprend des faces (3, 5, 7), chacune d'entre elles étant formée à partir de couches superposées de matière perméable à l'air. Une valve respiratoire (13) est fixée à la face centrale (3) par une pastille adhésive qui est imprimée sur la couche extérieure de la face. L'utilisation d'une pastille adhésive imprimée permet de fixer avec précision les composants sur le corps du masque très rapidement.
