Abstract
1. Un elemento filtrante estrechado de papel plisado (tal como se han definido en lo que antecede), que tiene hoyos de separación de pliegues cuya altura con relación al plano del papel está graduada en sentido longitud del elemento, de modo que se proporcione una separación de pliegues controlada en todo la longitud del elemento. 2. Un elemento filtrante, según la reivindicación 1, en el cual los hoyos de separación de pliegues están constituidos por depresiones con conicidad (como aquí se han definido en lo que antecede). 3. Un elemento filtrante, según la reivindicación 1, en el cual los hoyos de separación de pliegues en aquel lado del papel que ha de ser en uso, la superficie exterior del elemento con conicidad, están constituidos por depresiones con conicidad (tal como se han definido aquí en lo que antecede) y los hoyos de separación de pliegues en el lado opuesto del papel son de altura sustancialmente constante en toda la profundidad de cualquier pliegue. 4. Un elemento filtrante estrechado de papel plisado.
