Abstract

La présente invention concerne un procédé permettant de fabriquer un paquet dans lequel une pluralité d'articles absorbables (2) sont logés dans un corps d'emballage, ledit procédé comprenant une étape de plissage et une étape d'étanchéité. Dans l'étape de plissage, une pile (6) dans laquelle la pluralité d'articles absorbables (2) sont empilés dans une direction (D), est rentrée à partir d'une partie d'ouverture (3a) d'un corps de sac (3') qui devient un corps d'emballage vers l'intérieur par le biais d'un élément de prévention de morsure (4). À ce moment, on suppose que la pile (6) est comprimée de telle sorte qu'une dimension W1 dans la direction (D) devienne plus petite qu'une dimension W2 dans le sens de largeur du corps de sac (3'), et présente une posture dans laquelle la direction (D) coïncide avec le sens de la largeur du corps de sac (3'). Dans l'étape d'étanchéité, l'élément de prévention de morsure (4) rentré à l'intérieur au cours de l'étape de plissage scelle la partie d'ouverture (3a) du corps de sac (3') agencée sur un côté plus proche de la partie d'ouverture (3a) que la pile (6).
