Definitions

  • the present invention relates to a method for dividing a material into fibers, and more particularly to a method for making fibers of a continuously supplied molten material such as synthetics, minerals, and glass, by blowing a fluid such as steam, against a coherent stream of the material flowing out of a container.
  • a fluid such as steam
  • Another object of the present invention is to provide a method which produces the same amount of fibers while using 50%, or less, of the impinging fluid than the prior art.
  • diffusor walls 14 are respectively secured to members 1 and 2, and form a diifusor passage at the end of passage 10.
  • the diffusor permits expansion of the fluid stream, and is designed in accordance with the present invention to achieve particularly advantageous flow conditions, as will be described hereinafter in greater detail.
  • the passage 10 formed by diffusor walls 14 is elongated and rectangular in a horizontal cross section, and a plurality of outlet members 3 are advantageously arranged along the cylindrical guide surfaces 5 and passage 1%.
  • the guide surfaces 5 confront each other, and have opposite portions which are straight in axial direction of the tubular members 15 corresponding to generatrices of the respective cylinder surface.
  • the apparatus shown in FIG. 1 will operate even if used without diffuser, or with a conventional diffuser which is not designed in accordance with the present invention. However, the best efficiency and optimal results are achieved if the apparatus is provided with a diffusor in accordance with the present invention.
  • Another duct 21 connects this chamber with a curved chamber 25 extending along the outer surface of tubular member 16 in support member 15.
  • Chamber 25 communicates through a conduit 22 with a conduit in a connecting member 23 to which an inlet pipe for a fluid, such as steam, is welded.
  • the emciency of the arrangements of the present invention is further increased when the diffuser is constructed in such a manner that, without a detachment of the flow from the diffuser surface, the losses in the diffuser are held to a minimum.
