Conical foraminous formers 4, Fig. 1, are coated with fibrous pulp in a tank 1 by suction through tube 8, and whilst they are being coated a reciprocating shaking motion is imparted to them to consolidate the coating and render it more uniform. Thus, a horizontal shaking motion is applied by an eccentric or crank to a frame 3 that carries the formers, and preferably the frame is also reciprocated vertically as by an eccentric 19<1>. The frame 3 then rises to insert the coated formers into conical cups 6 where the coatings are subjected to pressure and suction to remove water, the resultant pulp cones are transferred to the cups and the cups move leftward, Fig. 1, to transfer the cones to a conveyer 7. The cones may then be trimmed by cutters. Fig. 3 shows a former comprising a perforated cone 10 covered with wire mesh 12x. The cone is pressed against the flange ...

System for making large objects from fibrous slurry

An improved method of and apparatus for the manufacture of moulded articles of fibrous material

... 691,853. Moulding articles from aqueous fibrous pulp. MULLER, K. June 17, 1949, No. 16171/49. Class 87 (ii). The pulp is fed through pipe c, Fig. 1, into vessel b and thence to moulding sieve a first at low pressure and then at high pressure, the water escaping through the sieve into vessel e. The object of the initial low-pressure feed is to preclude penetration of the fibre into the openings of the sieve. During this low-pressure feed the supply is throttled in pipe c and the level of the pulp rises slowly into the sieve. Vessel e is made so small that the level A of the water therein is just below the pulp level B within the sieve; the pressure forcing the water through the sieve (corresponding to the difference in levels) is therefore low. The water overflows at f. An outlet g for the water can be opened and closed as desired. d is a supply pipe for a gaseous pressure or heating means. Fig. 2 shows a modified apparatus in which the water vessel k is closed at the top and has pipes l ...
