Abstract

Paper dry-forming appts., comprises disintegrator and blower feeding airborne fibres to a distributor above a moving pervious belt below which is a suction box. The distributor houses a set of horizontally reciprocated rotary needle rollers, located above a perforated screen across the bottom of the distributor. Specifically the needle rollers are reciprocated transversely of their lengths, by an amplitude of at least half of the space between adjacent rollers.
