Abstract

L'invention concerne un masque et son procédé de production, un masque ayant des boucles latérales reliées au corps principal de masque pouvant ainsi être produit à grande vitesse.　Le masque (10) comprend : (a) un corps principal (20) de masque étirable dans une première direction (11) ; (b) des boucles latérales (40) en forme de feuille qui sont disposées sur le corps principal (20) de masque de manière à s'étendre dans une seconde direction (12) qui croise la première direction (11) et qui sont reliées à des sections terminales (20u, 20v) sur les deux côtés du corps principal (20) de masque dans la seconde direction (12). Les boucles latérales (40) sont étirables dans la première direction (11). Une bande (20r) de corps principal de masque étirable dans le sens de la largeur et une bande (40r) de boucle latérale comprenant une section qui est extensible dans le sens de la largeur sont transportées dans la même direction, empilées et reliées ensemble pour former une bande (10r) de masque composite. La bande (10r) de masque composite est découpée pour former des masques individuels (10).
