Abstract

RESUMEN Un producto absorbente que comprende una lámina superior permeable a líquidos (7), una lámina posterior impermeable a líquidos (8) y un núcleo absorbente (11) insertado entre la lámina superior (7) y la lámina posterior (8), dicho núcleo absorbente (11) que comprende una capa fibrosa absorbente (9), una capa de espuma de entrada de líquido (1) y una capa portadora (10), en el que una región transversalmente central (4) está dispuesta en la capa de espuma de entrada de líquido (1), dicha región (4) que se extiende a lo largo de la longitud longitudinal (L1) del núcleo absorbente (11), y que comprende una pluralidad de ranuras (2) dispuestas en un patrón, en el que las ranuras (2) están en forma de aberturas de ranuras dilatadas (3a) en una parte de dicha región central (4), que está comprendida en una parte intermedia (16) del núcleo absorbente, y las ranuras (2) están en forma de ranuras no dilatadas (3b) en partes de dicha región central (4), que están comprendidas en una o ambas de las partes frontal y posterior (15, 17) del núcleo absorbente; y un método para fabricar un producto absorbente (100), que comprende los pasos de: cortar (130) ranuras (2) en una región central (4) de una banda continua de material de espuma de entrada de líquido (101) y extender (131) la banda de forma transversal en la dirección transversal de la máquina, por lo cual las ranuras (2) se dilatan en aberturas de ranuras dilatadas (3a); aplicar adhesivo (132) a una banda continua de material portador (110); combinar (133) la banda continua de material de espuma de entrada de líquido (101) y cortar (134) los componentes de capa de espuma de entrada (126) de la banda combinada (125); proporcionar (135) componentes absorbentes (122); insertar (136) el componente de capa de espuma de entrada (126) y el componente absorbente (122) entre bandas continuas de material de lámina superior (107) y material de lámina posterior (108); unir (137) al menos el material de lámina superior (107) y el material de lámina posterior (108) a lo largo los bordes exteriores del producto absorbente; cortar (138) el material combinado en una forma deseada, obteniendo así el producto absorbente (100).
