A carding drum has a peripheral surface which has a substantially vertically extending release portion. The drum is operable to rotate in a predetermined sense whereby said release portion is moved downwardly. Inlet means supply fiber material to said peripheral surface outside said release portion. Workers and stripples cooperate with said peripheral surface between said inlet means and said release portion in the direction of movement of said peripheral surface during rotation of said drum. A web-forming conveyor succeeds said drum and has a web-forming surface formed with suction openings. An air nozzle is connected to a blower to receive compressed air therefrom and extends throughout the length of said drum and has an outlet orifice arranged to discharge said air in a substantially downwardly directed stream, which flows tangentially past said release portion to impinge on said suction surface. During rotation of the drum, fibers are released from said release portion and entrained by said airstream in a substantially vertical direction to said suction surface through an open space. A baffle defines a lower limit of said release portion and extends approximately radially relative to said drum and close to said peripheral surface thereof.
