  • Apparatus for transforming an air-fibre dispersion stream in the manufacture of homogeneous fibrous materials
    Patent number: 4003105
    Abstract: In the apparatus of the invention a slot nozzle is arranged on an outlet of a pipe for supplying an air-fibre dispersion stream into a chamber with said nozzle disposed therein so that the slot of the nozzle is perpendicular to chamber side walls. A body with a curvilinear cambered plane is disposed in the chamber and is essentially a cylinder with a generatrix length of no less than the nozzle slot length. Said cylinder has a diameter no less than 1.2 times the nozzle slot width and is spaced under said nozzle at 0.3 to 1.0 cylinder diameter. In addition, a spacial lattice, spanning over a chamber cross-section for smoothing the air-fibre stream, is placed under the cylinder 2 to 6 diameters of the latter down stream from the nozzle and the cylinder.
