ABSTRACT:
The fleece spinning unit has a spinning nozzle system, a cooling shaft, a stretching aperture, a diffuser shaft, a continuously moving fleece receiving conveyor and a device for feeding process air and for drawing outflowing air through the fleece receiving conveyor. The cooling shaft has a shaft wall provided with a plurality of air orifices. Thus process air required for the cooling is fed into the cooling shaft and is at least partially drawn through the fleece receiving conveyor. The thickness of the spun fleece is measurable on the fleece receiving conveyor downstream of the diffuser shaft in the transport direction. A measured value/set-point comparison is made and on deviation of the measured value from the set-point the setting angles of opposing air control flaps which are located at the entrance of the stretching aperture are changed. On a positive deviation of the measured value of the thickness from the set-point the setting angle is increased. On a negative deviation from the set-point the setting angle is decreased.
