Abstract

Dispositivo para la fabricación de bolsas de una lámina continua, de dos capas, de un material termoplástico, con barras dispuestas paralelamente entre si a determinado intervalo sobre un cilindro giratorio con objeto de apoyar la lámina continua alimentada, entre las que se han dispuesto unos listones de contrapresión de un dispositivo de separación y soldadura transversal que se pueden hacer salir hacia los listones soldadores que actúan conjuntamente con aquellos, pudiéndose mover las barras de apoyo así como los listones de contrapresión el uno en dirección al otro y el uno alejándose del otro, en una línea en zigzag, con transmisión de la lámina continua que pasa entre ellos, así como con un dispositivo para el transporte de las bolsas formadas mediante costuras soldadas de separación, que se caracteriza porque las barras de apoyo (19), que sirven para la recogida y sujeción de la lámina continua (1), pueden hacerse salir y entrar axialmente por lo menos por la anchura dela lámina continua, guiándose los listones de soldar (41), por lo menos en la zona del sector del cilindro (30.2, 30.3), en la que se encuentran las barras de apoyo (19) en su posición retraida y se llevan a cabo las costuras soldadas de separación, concéntricamente a la superficie envolvente del cilindro expuesta a los listones de contrapresión (15), fuera de la misma con la misma velocidad angular.
