Abstract
An apparatus and a method for guiding and depositing synthetic fibers to form a nonwoven web is described. The apparatus has a drawing device, a deposit belt, and a plurality of guidance means disposed between the drawing device and the deposit belt, which form in pairs numerous merging guidance pathways for the guidance of a fiber curtain formed by the fibers. The guidance means have numerous air intake slits beneath the drawing device, which enable an introduction of a secondary airstream. Numerous air conducting elements disposed on one of the guidance means are associated with at least one of the air intake slits. In this manner at least one of the sub-streams of the secondary airstream laterally adjacent to the fiber curtain can be introduced to the fiber stream at an inflow angle that is at a right angle to the deposit belt.
