An apparatus for formation of a course of fibrous materials on a perforated forming wire mesh with an underlying suction box and an overlying fiber distribution box, in which a pair of rotating, perforated drum cylinders are provided for the delivery of a stream of air-fluidised fiber, which is then flung out down on to the wire mesh by the drawing-down of air by the suction box from the upper end of the distribution box, cover plates (18) is arranged at a distance below the upper level of the drum cylinders, which plates substantially shield-off the free flow of air down through the vertical spaces between the drums themselves and between the drums and the adjacent side walls of the distribution box. |
