- Nonwovens or nonwoven fabrics are defined as structures of limited length fibers, continuous fibers or cut fibers, which are in some way joined together to form a nonwoven, namely a fibrous layer, a batt, and are connected to one another in a suitable manner.
- the publication DE 101 14 553 A1 discloses a process for the production of a thick, thermoplastically deformable, fiber-reinforced semi-finished product in which reinforcing fibers are dry-blended by means of an airlay or carding process to form an endless web, wherein the obtained nonwoven fabric is consolidated by needling. From the document DE 10 2004 051 334 A1 a method for producing a three-dimensional structural component is known, wherein this has a dimensionally stable textile structure.
- DE 100 52 223 A1 discloses a multilayer, flexible, carbon-containing layer paper which is produced by the air-laid method.
- the production of nonwovens from a wide variety of starting fibers is the wetlay method, wherein the fibers are present in a water bath and are formed out of this into a nonwoven, which is generally used for the production of carbon fiber nonwovens application, as well as the Airlay Kunststoff using From air and needle devices or needle-equipped rolls fibers to nonwovens which, however, is not applicable to carbon fibers.
- the use of the airlay method on carbon fibers leads in particular to mechanical interventions on the fiber and ultimately to impairments of the high-performance fiber.
- the present invention has for its object to provide an arrangement and a method for producing nonwovens, which make it possible to treat the fibers to be processed during manufacture gently and in particular homogeneous and according to any specifications on a nonwoven web in nonwoven form.

- the air streams can be realized by a plurality of individual nozzles, wherein it is crucial that a turbulent or chaotic and especially non-directional flow is formed within the air shaft.
- the air streams are generated by one or more rotating and horizontal, in particular arranged within one or more planes air rollers. These can also be set variably.
- the air rollers are designed as rotating pressure tubes, at the periphery of a plurality of nozzles are mounted on the surface. Driven by corresponding electric motors, the air rollers are rotated, so that the nozzles arranged thereon, which are also different Abstrahlwinkel may have, spatially distribute the exiting air, so that it comes within the duct to a thorough mixing of the carbon fibers.
- the suction (step VI.) Is varied in the suction power and / or adjusted, whereby the density of the web can be adjusted or varied accordingly.
- Another possibility of density variation is adjusting the speed of a correspondingly provided conveyor belt or a shape moving past the trickle zone, so that the density decreases at higher speed and the density of the carbon fibers increases at reduced speed.
- the shape or the depositing surface is guided past the lower outlet, the trickling zone, of the air duct, the conveyance being linear or spatial, the surface perpendicular of the form or of the laying surface corresponding in sections to the perpendicular of the air shaft.
- the trickling carbon fibers always impinge perpendicularly on the surface of the mold and attach themselves there to the surface, whereby a fleece is produced which corresponds exactly to the surface curve or surface shape of the mold.
- the thermal bonding fibers are melted on the surface of the fleece so that a progressing envelope is produced above the fleece.
- the composition of the fibers is not changed.
- the carbon fibers are cut during feeding by means of a cross-cut.

- the generated air flow takes place only in the direction of the upper part of the air shaft. Underneath the air rollers, unhindered trickling of the fibers onto the mold or laying surface or the conveyor belt is thus possible.
- the air rollers whose complete rotation is to be mentioned, being radiated over the entire range of rotation in all directions air. In this case, the air can escape from the nozzles at low speeds, nevertheless due to the large number of nozzles arranged, this leads to optimum turbulence.

- a further particular embodiment with respect to the invention is given when a method for producing a nonwoven fabric for a three-dimensional component comprises the step of passing a shape of the three-dimensional component to be produced on a fiber dispenser, in particular with an arrangement according to the invention Fibers from the fiber output are applied at the point of impact of the mold in the direction of the surface normal. In this case, it is ensured that the trickling fibers form a fleece on the surface of the mold exactly following the shaping of the mold, with no tensions of the fibers, for example due to kinking, bending or the like, which usually occur when laying a two-dimensionally produced fleece on a curved shape occur.
- Such components may be, for example, the floor of a motor vehicle or flaps of luggage compartments in aircraft, this list is only to be considered exemplary. Since the fibers are exactly adapted to the shape during laying into a nonwoven fabric, the production of an almost stress-free component takes place in this way.
- the speed of movement of the mold and / or a suction below the mold are varied.
- the density of the nonwoven fabric is adjustable. With higher suction, the material flow of fibers in the trickle zone increases, so that the density of the fleece is increased. With faster movement of the mold, the density is locally reduced because fewer fibers can trickle onto the mold per time.
