16493 ABSTRACT OF THE DISCLOSURE The apparatus has a spinneret, a cooling shaft, a stretching aperture, a diffruser shaft, a fleece delivery conveyor and a device for feeding process air and for pulling or drawing outflowing air through the fleece delivery conveyor. The cooling what has a shaft wall provided with a plurality of air orifices. Process air required for the cooling is fed into the cooling shaft. The cooling shaft is provided with an upper intensive cooling region and a lower additional cooling region and suitable air flow dividing guiding walls connected to the outside of the shaft wall. Air control flaps which have an outlet gap opening to the stretching aperture and which form a wedge pointing in the feed direction of the endless filament are connected upstream of the stretching aperture to the shaft walls. The diffuser shaft is provided with pivoting wings defining the passage cross section which are each movable about one horizontal axis. The device for pulling or drawing outflowing air has an adjustable damper above and/or below the fleece delivery conveyor with which the width of the outflowing air measured in the transport direction is adjustable. The apparatus operates with a single process air flow which is dividable into one partial flow for the intensive cooling region and another partial flow for the additional cooling region.
