Abstract

QUE COMPRENDE: A) PROVEER UNA ESTRUCTURA CONTINUA EN CAPAS SIMILAR A TELA, QUE TIENE REGIONES DESIGNADAS DE CORTE Y QUE COMPRENDE UN MATERIAL EN PARTICULAS ENTRE CAPAS DE CONTENCION, DONDE DICHAS CAPAS SON CAPAS FIBROSAS ABSORBENTES; B) APLICAR ENTRE 45 g/m� Y 75 g/m� DE UN MATERIAL TERMOPLASTICO EN ESTADO LIQUIDO A LA ESTRUCTURA CONTINUA EN CAPAS POR LO MENOS POR UNA PARTE DE LAS REGIONES DESIGNADAS DE CORTE, DE MODO QUE EL MATERIAL TERMOPLASTICO SE UNE A LAS CAPAS DE CONTENCION DONDE SE APLICA; C) PERMITIR QUE EL MATERIAL TERMOPLASTICO SE SOLIDIFIQUE; Y D) CORTAR LA ESTRUCTURA CONTINUA EN CAPAS EN LAS REGIONES DESIGNADAS DE CORTE PARA PROVEER ESTRUCTURAS INDIVIDUALES EN CAPAS. SE REFIERE TAMBIEN A UNA ESTRUCTURA INDIVIDUAL EN CAPAS QUE SE OBTIENE MEDIANTE EL PROCESO YA DESCRITO. DICHA ESTRUCTURA INDIVIDUAL TIENE USO COMO ELEMENTO ABSORBENTE EN ARTICULOS ABSORBENTES DESECHABLES TALES COMO PANALES, PRENDAS DE INCONTINENCIA PARA ADULTOS, VENDAJES Y SIMILARES
