Abstract:
A method and apparatus for depositing synthetic filaments to form a non-woven web, wherein the filaments are drawn off from a spinneret through a drawing unit in a row-shaped arrangement using a feed fluid, accelerated into a guide channel and blown out as a filament stream toward an advancing deposit belt. The filament stream is deflected immediately before it impacts upon the deposit belt unilaterally in the advancing direction of the deposit belt in such a way that the filaments impact upon the deposit belt at an angle of
