Abstract

1. Dispositivo para el cierre de sacos grandes, de material termoplástico, en el que se coloca aproximadamente en posición vertical el extremo vacío superior del saco, se pliega en zig-zag, se contrae y se asegura contra la posibilidad de que abra, caracterizado porque el plegado en zig-zag (1) contraído del extremo del saco es perforado para su fijación por medio de agujas salientes (7). 2. Dispositivo según la reivindicación 1, caracterizado porque los agujeros perforados se comprimen, en sentido axial, entre unas mordazas que se pueden mover la una en relación a la otra hasta la solidificación suficiente del material plastificado por las agujas (7). 3. Dispositivo según las reivindicaciones 1 ó 2, caracterizado porque el borde superior (10) del extremo del saco se dobla una o varias veces antes del plegado en zig-zag (1.1, 1.2). 4. Dispositivo, según las reivindicaciones 1 ó 2, caracterizado porque se dobla una o varias veces el plegado en zig-zag contraído (1.3, 1.4, 1.6) antes de su fijación. 5. Dispositivo según una de las reivindicaciones 1 ó 2 a 4, caracterizado porque se unen los cantos delanteros del saco contraído en un plegado en zig- zag mediante la acción de calor. 6. Dispositivo según una de las reivindicaciones 1 ó 3 a 5, caracterizado porque para la fijación se lleva a cabo una costura de soldadura transversal 818) a través de todas las capas de un extremo de saco contraído en un plegado en zig-zag y, si fuese necesario, doblado una o varias veces. 7. Dispositivo según una de las reivindicaciones 1 a 5, caracterizado porque el plegado en zig-zag (1) contraído se coloca entre las mordazas de sujeción (3, 4) que llevan los orificios (5) alineados entre sí, habiendose previsto un listón agujas (7), y pudiéndose introducir las agujas (7) en los orificios (5). 8. Dispositivo según la reivindicación 7, caracterizado porque el listón (6) lleva tres agujas (7). 9. Dispositivo según la reivindicación 1, caracterizado porque el plegado en zig-zag se sujeta mediante uniones por soldadura que pasan por aquél en forma de barras. 10. Dispositivo para el cierre de sacos grandes.
