Beschreibung
Zusammenfassung:	A method of forming a pulp-moulded article comprises the steps of (a) providing a container 102 with a water permeable end 106; (b) introducing fibre containing slurry 112 into the container; (c) applying a positive pressure on the fibre containing slurry to force water out of the container via the water permeable end thereby forming layers of fibre on the water permeable end. The positive pressure may be combined with a vacuum to achieve better results. The exerted pressure may also be fully controlled to achieve different profiles by means of a feedback response mechanism. The pressure may be applied by a piston (202 figure 7) which acts as the upper mould half in which case the forming and cold pressing stages may be combined in one stage. Also included is an apparatus for forming pulp moulded articles using the above method.
