16471 ABSTRACT OF THE DISCLOSURE The process for making the spun fleece proceeds in a filament-spinning unit having a spinning nozzle system, a cooling shaft, a stretching aperture, a diffuser shaft, a continuously moving fleece recovery conveyor and a device for feeding process air and for drawing outflowing air through the fleece recovery conveyor. The cooling shaft has a shaft wall provided with a plurality of air orifices. That allows process air required for cooling to be fed into the cooling shaft. That air flow at least partially is drawn through the fleece recovery conveyor. The thickness of the spun fleece is measured on the fleece recovery conveyor in the transport direction downstream of the diffuser shaft. The measured value is compared with a predetermined set value. On deviation of the measured value from the set value the setting angle of the air control flap or flaps which are located adjacent the entrance of the stretching aperture is changed. On a positive deviation of the measured value of the thickness from the set value the setting angle is increased, on a negative deviation the set value is reduced.
