Abstract

The invention relates to a forming head (1) for dry forming a fibrous web, which forming head is positioned above a forming wire opposite a suction unit. The forming head (1) is divided into at least two independent interconnected distribution units (2,3,4,5) each of which comprises at least one revolving roller (11,12,13,14,15,16,17,18,19) provided with protruding spikes (12). By dividing the forming head (1) into a plurality of interconnected distribution units (2,3,4,5), a more efficient disintegration of agglomerates, shadows and/or lumps in the fibre material is achieved compared to the known forming heads, thereby ensuring a more homogenous final product.
