Definitions

  • the invention relates to a nonwoven layer, which in particular is suitable for large laying widths, with the features in Preamble of the main claim.
  • Such a fleece layer is known from practice. He has two main cars with two endless and on the main car conveyor belts and a Discharge belt. A support carriage is for the conveyor belts Supporting a horizontal lower conveyor belt run intended.
  • the fleece layer also has additional sheets for lateral edge guide of the band.
  • the conveyor belt run is lifted off the support car and at an angle led down to the frame. This has the emergence of one Opening between the lower conveyor belt and the deposited fleece in the result of the driving movements the car entering air and for swirling the Fleece can provide.
  • the invention solves this problem with the features in the main claim.
  • the design of the belt guide in the support carriage according to the invention has the advantage that the undesirable wind influences are avoided and the lower conveyor belt runs largely retain their covering function.
  • the support carriage can move back and forth in relation to the deposited fleece without disturbing or damaging the fleece.
  • the tape guide according to the invention can also be present on several support carriages.
  • At least one the lower support car rigid with the upper main car or superstructure is preferably integrated. This has the advantage that the construction effort is minimized. In addition, the drive transmission more direct, precise and less prone to wear. In addition this design is particularly compact. In addition, this can Carriage arrangement particularly favorable in the frame of the Store, guide and drive the fleece layer.
