    • An apparatus for producing fibrous nonwoven fabrics of at least two superposed fibrous web layers of equal or different structure is disclosed by using at least two successively arranged cards (2, 5) in a card set, means for discharging the fibrous webs from the card or the like in one direction, the discharged fibrous web layers being fed to a finishing unit (15) such as a calendar and the like, each card being provided with at least one doffing point (3, 4; 3',4'). The improvement comprises a conveying means (7, 12) carried adjacent and following the doffing point which is tiltable upwardly or downwardly at a predetermined angle. Transport devices (8, 9, 13, 14, 16) are mounted above and beneath the cards in communication with conveying means for transporting discharged webs.
