Abstract

1427584 Paper-making machines A AHLSTROM OSAKEYHTIO 13 April 1973 [21 April 1972] 17979/73 Heading D2A To form a non-woven fibrous web, for example of paper, a suspension of fibres is divided and passed through a plurality of parallel passages 5, 6 in which it is accelerated to emerge as jets in a common chamber 11 in which the jets are reunited, the suspension is then deflected approximately through 90‹ by surface 9, accelerated through constriction 8 and deflected again substantially through 90‹ by surface 10, and the suspension is passed through an outlet channel 12 of constant depth in which turbulence in the suspension is allowed to decay, the resulting web 13 then being deposited on the wire 1 of a machine for drainage. A transverse distributor 3 supplies the suspension to the passages 5 and is inclined to their axes to increase the inlet area of the passages 5 and thus reduce clogging. The suspension can be highly concentrated, e.g. 1-6% of fibres by weight. The passages 5 are cylindrical and lead into flattened passages 6 of reduced cross-sectional area which accelerate the suspension for delivery through outlets 7 into transverse chamber 11. In a modification (Fig. 3, not shown) the constriction 8 is defined by a spring plate (17) and is adjustable, the lower lip of the outlet channel is formed by a thin plate (19) and the cross-sectional area of the distributor 3 is also adjustable.
