Abstract: 900,378. Moulding pulp articles. DIAMOND NATIONAL CORPORATION. April 4, 1961 [June 23, 1960], No. 12045/61. Class 87(2). [Also in Group XVII]. A moulded pulp article, (see Group XVII) particularly of undercut shape, is formed by first making a preform on a mould of a shape different from that of the finished article e.g. a shape which is not undercut, and then transfering it to a die of the desired final shape. As shown, a layer of pulp is sucked on to a mould 10 on a rotating drum 12, the formed layer is sucked against a die 26 of the desired final shape, blown on to a conveyer, and dried in an oven 34. During removal of the article from the die, the shape of the article is deformed, due to its undercut form, however on drying it returns to the shape formed by the die. The dies 26 can have inward sloping walls or a plurality of indented lug shapes in the side walls.
