Abstract
A method and apparatus for producing a continuous web of material (36) on an endless belt (24). Fibers suspended in a carrier gas are transported from a transport conduit (12) through a transition part (38) of zig-zag configuration, having cross-section which tapers or narrows in the flow direction. Arranged at the outlet aperture of the transition part is a coarse-particle separator means (22) which incorporates a curved, convex surface (60), an accept outlet (48), and a reject outlet (54). The carrier gas is deflected around the convex surface, as a result of the ensuing Coanda Effect, and transports acceptable fine fibers to the accept outlet (48), while coarse reject particles, due to their greater kinetic energy, pass in a straighter path to the reject outlet (54). The accept outlet leads directly to a distribution chamber (52) which is located above the endless belt (24), and opposite which there is provided a suction box (32) for extraction of the carrier gas.
