Abstract

L’invention concerne un procédé permettant de fabriquer un article vestimentaire jetable possédant une première région de sangle abdominale (S1) couvrant une partie de la sangle abdominale de l’utilisateur, une seconde région de sangle abdominale (S2) couvrant la partie restante de la sangle abdominale de l’utilisateur, et une partie centrale (C) couvrant l’entrejambe de l’utilisateur. Le procédé de fabrication comprend : une étape de production d’une feuille composite obtenue en agençant un élément élastique à enfiler (FU), destiné à empêcher l’article vestimentaire de glisser et de tomber lorsqu’il est porté, sur une bande de tissu transportée conformément à une ondulation prédéfinie ; une étape de division de ladite feuille composite pour obtenir une première feuille divisée et une seconde feuille divisée ; une étape de déplacement desdites deux feuilles divisées par rapport à une direction latérale (D) perpendiculaire à une direction longitudinale (L) ; une étape de décalage de la phase desdites première et seconde feuilles divisées l’une par rapport à l’autre, dans la direction de transport de celles-ci ; et une étape d’agencement de la partie centrale (C) aux fins d’obtenir un corps stratifié.
