16470 ABSTRACT OF THE DISCLOSURE The apparatus for making a spun-filament fleece from a stretched thermoplastic monofilament comprises a combined spinning unit made up of separate spinning units each having a plurality of spinning nozzles arranged in rows over a rectangular cross section, a blower shaft, a stretching shaft and a wire screen conveyor for the finished deposited fleece. The blower shaft is provided with air orifices for admission of stretching air simultaneously acting as a cooling means. The stretching shaft has stretching shaft walls which are, if necessary, movable or adjustable with an accelerating device with a venturi nozzle like vertical cross section. At least two separate spinning units with separate groups of spinning nozzles are located above the blower shaft. At least one separating wall located between individual spinning units divides the blower shaft into separate portions for separate bands of monofilaments generated by the separate groups of spinning nozzles. The separate spinning units can be supplied with different thermoplastic material from different extruders.
