Abstract
A device for dry-forming a fibrous web, in which a plurality of fibers or fiber mixtures is supplied to a forming head by means of an air flow, is described. The forming head includes a forming outlet arranged above a gas-permeable deposit belt. The fibers deposited on the deposit belt within a forming zone are continuously conveyed out of the forming zone by the deposit belt. A clearance of the forming zone formed between the forming head and the deposit belt is shielded with respect to the surroundings by several sealing means. To obtain as uniform a composition of the fiber layer as possible when depositing the fibers, the sealing means arranged on a feed side forms an inlet opening having an adjustable inflow cross-section through which a defined secondary air flow flows from the surroundings into the clearance.
