Abstract

Mejoras en la fabricación de colchones a base de material espumante. Partiendo de la fabricación de colchones mediante la utilización de dos semimoldes que en su conjunto determinan un receptáculo formal y dimensionalmente coincidente con el colchón a obtener, semimoldes en cuyo fondo se establecen tapas de naturaleza textil que quedan integradas en el bloque de espuma y que configuran las superficies de descanso del colchón, consisten por un lado en utilizar tapas de un material textil no absorbente del líquido espumante, como por ejemplo a base de fibras sintéticas, para evitar que el líquido espumante impregne a la cara externa de las tapas, consiguiéndose el aspecto acolchado de la superficie externa del colchón, bien mediante la utilización de semimoldes con relieves apropiados en su fondo, bien mediante presión posterior y superficial del mismo, con la colaboración de machos adecuadamente configurados, antes de que se produzca la total solidificación de la espuma. Además seuha previsto que finalmente el bloque sea sometido a un profuso perforado, por ejemplo con rodillos de agujas muy finas, que no afectando a la tela perforen la corteza no transpirable definida por la capa limite del bloque de espuma, convirtiéndola en perfectamente transpirable.
