Abstract

La presente invención se refiere a procedimiento para fabricar un filtro en forma plegada, que comprende las etapas de: proporcionar una hoja de material no tejido termoplásticamente soldable; doblar la hoja para formar un paquete plegado que comprende una pluralidad de pliegues paralelos cada uno de los cuales comprende una bolsa de pliegue unida mediante un par de dobleces paralelos en un espaciamiento de pliegue fijo, este paquete de pliegue tiene orillas opuestas perpendiculares a los pliegues; proporcionar dos pares de herramientas de agarre, cada par comprendiendo una herramienta de agarre superior y una herramienta de agarre inferior, con cada herramienta teniendo una pluralidad de dientes que tienen espaciamientos fijos y diseñada para interacoplar con la otra herramienta del par; agarrar el paquete plegado entre las herramientas adyacentes a cada orilla del paquete de manera que el material no tejido se proyecte más allá de las herramientas de agarre por 1.5 a 2.5 veces el espaciamiento de pliegue fijo; doblar el material proyectante en la misma dirección adyacente a cada orilla para formar porciones dobladas de los pliegues, estas porciones dobladas yaciendo contra las herramientas de agarre y superponiendo al doblez cercano del pliegue adyacente por 0.5 a 1.5 veces el espaciamiento de pliegue; y térmicamente soldar la porción doblada de cada pliegue contra la porción doblada del pliegue adyacente, y remover las herramientas de agarre superior e inferior.
