Abstract

Perfeccionamientos en la fabricación de bolsas de plásticoa partir de una banda de material plásticola cual se dobla en sus bordes laterales para formar paneles solapantes; se hace avanzar repetidamente la banda en incrementos predeterminados de una longitud unitaria de bolsa; se sella térmicamente y longitudinalmente los panales solapantes entre sien una longitud de por lo menos la porción principal de una unidad de bolsa; se sella térmicamente entre si los dos paneles solapantes de cada unidad de bolsamediante la formación de dos juntas longitudinales que se solapan parcialmente para proporcionar una junta longitudinal delantera y una junta longitudinal trasera con respecto a la dirección de desplazamiento de la bandaformándose la junta longitudinal trasera de cada unidad de bolsa simultáneamente con la junta longitudinal delantera de la siguiente unidad de bolsa adyacente.
