Abstract
An apparatus for air-laying of a material in the form of fibers or granules onto a running band. The apparatus includes at least one delimited space arranged at a first surface on an at least partially air-permeable endless running band. A vacuum exists in the space during operation and the band runs successively over the space. This takes place concurrently with air being sucked through the band into the space. At least two rotatable support elements are placed in the space in order to counteract down-bending of the running band. The support elements have a rotational direction generally coinciding with the running direction of the band.
