Abstract

To produce non-woven materials, endless filaments in the form of a warp are drawn off a filament draw-off nozzle to which are joined a filament offlet, a filament guide tube and a spreading extruder. An amount of compressed air under high pressure is admitted to the filament draw-off nozzle, and by means of the spreading extruder provided with Coanda shells the warp is loosened before impacting on a screen conveyor. In order to achieve as evenly as possible a distribution and loosening of the warp, slot nozzles are provided on either side of the spreading extruder, which are supplied with a reduced amount of compressed air under relative low pressure. Simultaneously, a reduction of the amount of compressed air at the filament drawoff nozzle takes place. The additional air, supplied via the slot nozzles, surprisingly makes possible a considerable improvement in the spreading of the warp, and at the same time a savings in energy is also achieved in connection with the reduction of the amount of compressed air at the filament draw-off nozzle, while the filament draw-off force is maintained.
