Abstract

Fiber material is conveyed over a sieve-like surface to remove dust from material. The fiber material is thereby exposed to a suction airstream which is guided through the sieve-like surface and which is guided away from the fiber material at an acute angle which is formed opposite to the fiber transport direction. The fiber material may be aligned in parallel before it is exposed to the suction airstream. In order to orient the suction airstream at the desired acute angle relative to the fiber transport direction, the fiber material is guided over sieve orifices which are inclined at the acute angle opposite to the fiber transport direction.
