Abstract
A method and a device for the dry forming of a fiber web, in which a multiplicity of fibers or fiber mixtures are fed to a forming head by means of an air flow is described. The forming head produces a fiber stream which is introduced into a clearance of a forming zone between the forming head and a laydown belt. To obtain as uniform a construction of the fiber layer as possible during the laying down of the fibers, the fibers of the fiber stream run through the clearance within the forming zone with free sections of different lengths. To this end, the forming head and the laydown belt are held in a non-parallel arrangement, with the result that the clearance is formed by different spacings between the laydown belt and the forming outlet of the forming head.
