Abstract

Un método de producción de bolsas repetidamente obturables que incluye los pasos de doblar una longitud de lámina termoplástica a través de parte de su anchura original para producir una lámina doblada que tiene una porción doblada que discurre longitudinalmente a la lámina, que tiene un borde doblado cuya porción doblada se extiende a través de parte de la anchura original de la lámina y una porción no doblada que se extiende desde la porción doblada hasta el otro borde de la lámina; en una dirección perpendicular al borde doblado y a intervalos regulares a lo largo del borde doblado, soldar la porción doblada conjuntamente para formar bolsillos individuales de igual tamaño que tienen los bordes de la pared soldados a lo largo de la longitud de la lámina; cortar la lámina, a través de la anchura de la lámina y a lo largo de la línea de las soldaduras, para producir bolsas individuales, cada una de las cuales tiene una boca, bordes soldados y una porción de solapa extendida; llenar cada bolsa, a través de su boca, con el contenido deseado y doblar la solapa extendida por encima de la boca para formar la solapa alrededor de la bolsa; caracterizado porque, en el momento de formar la porción doblada de la lámina, se coloca, en una dirección paralela a los bordes de la lámina, un sujetador repetidamente obturable y en una posición predeterminada para estar inmediatamente debajo de las bocas de las bolsas, en el que el sujetador repetiblemente obturable consta de dos tiras de cierre acoplables entre sí en posición aplicada, teniendo cada tira de cierre una porción de base, y porque, mientras las tiras son acopladas entre sí, se sueldan las porciones de base de cada una de las dos tiras de cierre acoplables entre sí a las superficies encaradas de la lámina respectivamente en la porción doblada, y en le que las tiras de cierre se desacoplan entre sí después de soldar el sujetador repetidamente obturable, haciéndose las tiras de cierre para acoplarse entre sí después de llenar la bolsa y antes de formar la solapa extendida sobre la bolsa.A method of producing repeatedly sealed bags that includes the steps of folding a length of thermoplastic sheet through part of its original width to produce a folded sheet having a folded portion that runs longitudinally to the sheet, which has a folded edge whose folded portion extends through part of the original width of the sheet and an unfolded portion that extends from the folded portion to the other edge of the sheet; in a direction perpendicular to the folded edge and at regular intervals along the folded edge, weld the folded portion together to form individual pockets of equal size that have welded wall edges along the length of the sheet; cut the sheet, across the width of the sheet and along the weld line, to produce individual bags, each of which has a mouth, welded edges and an extended flap portion; fill each bag, through its mouth, with the desired contents and fold the flap extended above the mouth to form the flap around the bag; characterized in that, at the time of forming the folded portion of the sheet, a repeatedly sealed fastener is placed in a direction parallel to the edges of the sheet and in a predetermined position to be immediately below the mouths of the bags, in the one that the repeatable fastener consists of two closing strips that can be attached to each other in the applied position, each closing strip having a base portion, and because, while the strips are coupled to each other, the base portions of each of them are welded together. the two closing strips that can be attached to each other to the facing surfaces of the sheet respectively in the folded portion, and in which the closing strips are disengaged from each other after welding the repeatedly sealed fastener, making the closing strips to engage each other after filling the bag and before forming the extended flap over the bag.
