Abstract The invention relates to a process and an apparatus for the dry forming of a material web from a long-fiber material, wherein fibrous material is blown into a forming space to form a porous material web on a wire passing through the forming space. The dry forming of long fibers in lengths of at least 20 mm is problem- atic. In accordance with the invention, this problem has been solved in such a way that - the fibrous material is blown into the forming space by means of at least one air current (A) that is substantially horizontal and-transverse to the wire, - the fibrous material is guided onto the sur- face of the wire (1) by means of an air current (D) that is substantially vertical and passes through the wire downwardly, - and that the desired material web (F) is formed by the combined effect of said horizontal and vertical air currents. (Figure 1)
