Now, by means of a Vornadelmaschine 110 arranged laterally of the conveyor, the supply of a pre-needle punched ground fabric 66, on which the profiled fiber accumulation is stored. Finally, a second pre-needle-punched nonwoven is supplied as cover fleece 72 from above, so that ultimately a profiled nonwoven 80 in sandwich form is formed, which is fed to a solidification device 88.
  • the pre-needlepunched web formed by the pre-needling machine 110 is cut once in half to thereby form the base web 66 and the cover web 72.
  • the supply of the pre-needle punched ground fleece 66 and the pre-needle punched cover fleece 72 then takes place "around a corner" by guiding the base fleece 66 or the cover fleece 72 around a 90-degree curve.
  • the starting fleece 12 or the additional fleece which can be supplied from above in front of the dissolving unit 40, as a pre-needle-punched fleece.
  • Fig. 7 a possible embodiment of the dissolution unit 40 is shown.
  • the nonwoven intermediate product 78 conveyed by the feed roller 43 is supplied to the opening roller 42 by means of a depression 63, which is designed here as an overhead trough, which dissolves out the fibers or fiber flakes from the nonwoven intermediate product 78.
  • Feed roller 43 and opening roller 42 here have a same direction of rotation. But this can also be different.
  • the opening roller 42 carries the dissolved fiber material in the illustrated example case with it (eg with the help of another overhead trough).
  • a fan 64 may be on the feed roller 43 opposite side of the opening roller 42 may be arranged to convey the zoomed-in by the opening roller 42, dissolved fibers or fibrils targeted in a discharge shaft 65 downward. If there is no fan 64, the fibers or fiber flakes fall into the discharge chute 65.
  • a discharge roller 67 is arranged in the illustrated embodiment, which is preferably formed as a suctioned behind screen roller. But the discharge roller 67 may also be formed only as a screen roller, without Schusaugung. A roll with a perforated roll shell or a smooth roll are conceivable as a discharge roller 67.
  • a wall 69 is provided for guiding the fibers or fiber flakes. It is also possible, similar to in Fig. 4 provide several pedal wells that are individually deflected. When vacuuming the discharge roller 67, a particularly targeted feeding of the dissolved fiber masses succeeds.
  • the scattering can take place directly at the transfer point between feed roller 43 and opening roller 42 (not shown).
  • the output shaft 65 would be below this nip and the direction of rotation of the opening roller 42 would be reversed.
  • the fan 64 could then be located above the nip.
  • double needle machines which are needled from above and from below so that the previously produced profiled nonwoven 80 with its thick places and thin areas can be better passed through the constant distance between the perforated plates. It is preferred if the needle bars of the needle machine pass through an elliptical path of movement and thus do not hinder the fleece during transport in the conveying direction. As a result, braking effects can best be avoided.
  • the feeder 22 can be controlled.
  • all other relevant machine parameters can also be controlled by the control or regulating device 20, such as, for example, speeds of all components involved in web formation.
