    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.

    (54) DESIGN FOR FORMING A FABRIC OF FIBROUS WEIGHT
    one
    The invention relates to a paper machine design and can be used in the pulp and paper industry.
    A device for forming a fibrous web is known, comprising a mass conduit, a housing with feed channels and a turning chamber connected to the discharge channel 1.
    The disadvantage of this device is that the resulting fabric does not have a sufficiently high quality.
    The aim of the invention is to eliminate this drawback.
    This goal is achieved by the fact that the inlet channels are made flattened in the direction perpendicular to the direction of movement of the fibrous mass, and the rotating chamber has a narrowing located between the inlet channels and the outlet channel.
    FIG. 1 shows a device cross section; in fig. 2 is a section A-A in FIG.
    The device contains a mass pipeline. 1 connected to the housing 2, in which the supply channels 3 are made, and 4, the outlet openings 5 of which
    flattened vertically and may have a recess at the bottom. A rotating chamber 6 with a protrusion 7 located between the outlet channel 8 and the openings 5 of the supply channels 4 and the impact surface 9 is located in the housing of the device.
    The device is designed to operate on high
    10 concentration, which through the mass pipe 1 enters the channels 3 and 4. Due to the narrowing of the holes 5, the mass of the mass rises sharply and the jet hits the impact surface 9
    15 of the PTZ camera, and then passes through the constriction and, for the second time, hits the 6 surface of the housing located at the beginning of the output channel §. As a result of multiple mixing
    By mass 20, a well-dispersed three-dimensional fibrous mass structure is obtained, which, - the passage through the outlet channel, is finally stabilized and fed to the mesh.

    Formula and;
    A device for forming a per-30 lot of fibrous mass, containing a mass line, a body with inlet, -, -. Channels and a turning chamber connected to an outlet channel, characterized in that, in order to improve the quality of the casting (Cloths, the inlet channels are made flattened in a direction perpendicular to the direction of movement of the fibrous mass, and the turntable has a narrowing between the inlet channels and exhaust channel.
