Definitions

  • the invention relates to a method for distributing fibers in a layer, the fibers possibly being filted at the same time.
  • the distribution of the fibers is achieved by exposing the layer to a low- -frequency airborne sound field.
  • the fibers 1 are laid down onto an air permeable support 2 which is arranged in front of a sound emitter 4 located in a resonator 3.
  • the resonator 3 comprises a Hel holtz resonator and the sound emitter 4 comprises an electric loud speaker of the diaphragm type, which is mounted in a wall of the resonator.
  • the layer of fibers is exposed to 1 ow-
  • the fiber layer is fluidized and spreads uniformly over the support as indicated by a dash line 5. If the fibers 1 are of such character that they can be entangled with each other, or if the fibers during the fluidization are sprayed with an adhesive, there will be obtained in this way a bound fiber mat of uniform thickness.
  • the exposure of the fiber layer to sound can also take place from the upper side of the layer.
  • an accumulation of the fibers at one or more places as desired can be obtained by controlling the propagation of the sound field such that different portions of the fiber layer are exposed to sound fields of different strengths.
