The invention relates to a card for the production of a nonwoven fabric web. The object is to provide a new card enabling a high production rate and the manufacturing to be interrupted without any breaks in the web itself. The card comprises e.g. three main rolls (12, 17, 20), whereby slower transfer rolls (15, 16; 18, 19) acting as working rolls as well are provided between said main rolls. At least one flatting roll (23) is provided after the last main roll (20), from which roll (23) the fibers are advantageously transferred onto a conveyor wire (29) by means of an aspiration roller (28), said wire passing the fiber material web to further treatment.
