Abstract

Un procédé de réalisation d'ourlets internes dans un sac en plastique à partir d'une bande thermoplastique pliée comprenant une première étape dans laquelle on réalise simultanément un pli (5) le long du bord longitudinal (6) de la première feuille (3) avec une largeur supérieure à celle du ruban de fermeture et de transport à contenir, ce qui donne naissance au premier ourlet (11), et un pli (7) le long du bord longitudinal (8) de la deuxième feuille (4) de sorte que le pli (7) donne naissance au deuxième ourlet (12) et une deuxième étape dans laquelle est défaite la section médiane (10) dans la deuxième feuille (4) en la repliant sur la première feuille (3) et en plaçant le deuxième ourlet (12) face au premier ourlet (11). Figure de l’abrégé : Figure 10A method of producing internal hems in a plastic bag from a folded thermoplastic strip comprising a first step in which a fold (5) is simultaneously produced along the longitudinal edge (6) of the first sheet (3) with a width greater than that of the closure and transport tape to be contained, which gives rise to the first hem (11), and a fold (7) along the longitudinal edge (8) of the second sheet (4) so that the fold (7) gives rise to the second hem (12) and a second step in which the middle section (10) in the second sheet (4) is undone by folding it over the first sheet (3) and placing the second hem (12) facing the first hem (11).
