ABSTRACT:
A device having at least one, preferably a plurality of air turning foils situated upstream of and at the level of the region between a fiber distributor and an underlying moving forming surface. Terminal edge portions of the foils direct ambient air in the direction of forming surface movement to impart to fibers in transit between the distributor and forming wire a uniform velocity component of movement in said direction. Each foil preferably is convex from upstream of the foil when viewed in cross section, is parallel to and equidistant from the other, and has its terminal edge portion parallel to the forming surface.
