<p>Apparatus for spreading fibres uniformly over a forming conveyor has separate fibre distributors (10, 12), These deposit dry fibres onto a conveyor belt (60) which runs through a tunnel (51) into which fibre-dispensing openings of the distributors (10,12) discharge fibres. …<??>To reduce the likelihood of fibres accumulating on the tunnel walls (50 etc,) and possibly resulting in lumps falling onto the conveyor belt (60), the tunnel has seals (52, 54) at its belt-entrance and belt-exit ends, and beneath-belt suction produced by a suction box (64) is such that air flow into the tunnel through its sealed ends is insignificant. The distributors (10, 12) are contiguously side-by-side, an arrangement which minimizes the suction requirements.</p> |
