Abstract

L'invention vise à fabriquer un article ayant des absorbeurs épais qui améliorent la sensation produite sur la personne qui le porte, notamment donnant la sensation d'une toile moins grossière et moins rigide. L'invention concerne également son procédé de fabrication. Ce procédé consiste à placer un élément élastique (F) sur une bande (W) et à générer une bande composite (WF) formant la partie corps de l'article à porter ; à former des zones de découpe spécifiques (10) découpées à des intervalles spécifiques (P) par découpe partielle de l'élément élastique (F) et la bande (W) de la bande composite (WF) et à placer les absorbeurs (25) dans deux bandes composites (WF) à des positions correspondant aux zones de découpe (10).
