Title
(EN) METHOD AND APPARATUS FOR MANUFACTURING STAND-UP PLASTIC BAGS
(FR) PROCEDE ET APPAREIL DE FABRICATION DE SACS EN PLASTIQUE SE MAINTENANT DEBOUT
Abstract
(EN)
A method and apparatus (F) for manufacturing a stand-up plastic bag. The apparatus includes a section for supplying a continuous length of heat-sealable material (A), and a bag assembly section (B, C, D, E) connected to the supply section for producing a bag from the heat-sealable material having close sides, a closed bottom and an open mouth. The apparatus also includes a section for receiving the bag (F) after it is assembled and shaping the bag into a stand-up plastic bag. The bag shaping section includes a series of stations including: a first station for forming opposed faces, opposed sides, and a substantially flat bottom; a second station for creasing at least the bottom of the bag, so that the bottom folds inwardly and does not obstruct the front and back display surfaces of the bag; and a third station for unloading the bag.
(FR)
Procédé et appareil (F) de fabrication de sacs en plastique se maintenant debout. L'appareil comporte une section fournissant une longueur continue d'un matériau thermoscellable (A) et une section d'assemblage des sacs (B, C, D, E) reliée à la précédente et concourant à la fabrication de sacs présentant un fond et des cotés fermés et un orifice d'accès ouvert. L'appareil comporte également une section de réception (F) des sacs assemblés, qui les transforme en sacs en plastique se maintenant debout et qui comporte elle-même plusieurs postes, dont un premier poste de mise en forme des faces opposées, des côtés opposés et du fond sensiblement plat, un second poste de pliage, du fond au moins, de manière à ce que ce dernier se replie vers l'intérieur sans dissimuler les surface frontale et dorsale d'affichage du sac, et un troisième poste de décharge des sacs.
