ABSTRACT:
An apparatus for producing a nonwoven fabric from continuous filaments, which are drawn off at a high speed in the form of a tow, under the influence of a gaseous propellant, from spinnerets of spinning plates of a spinning beam and after passing through a filament draw-off apparatus are laid down by means of a delivery apparatus, embodied as a spreader, on a delivery belt moving in the production direction. In the production direction, two spinning beams are disposed spaced apart from one another, and at least one spinning beam is rotatable, together with the delivery and spreading apparatus, in a plane extending parallel to the delivery belt. A varied pattern of laying down of the nonwoven fabric, or a new nonwoven product, can thus be produced during ongoing operation.
