Definitions

  • the object of the invention to provide a novel method and device for making fibers or threads of the kind stated.
  • the hot liquid glass 'or slag mass is flown in a continuous and uniform thin stream onto a rapidly rotating body, such as a, disc of suitable material.
  • the liquid mass is thrown off the periphery of the disc by the centrifugal force and simultaneously formed into thin threads the threads of the normal or desired thickness.
  • a circular current of air under pressure is blown around the disc toward the discharge end of the device, this air current exerting a downward pressure on the fibers thrown off the disc so that they can be readily carried off.
  • i designates a furnace for melting the working material, such as glassor slag, the furnace being heated by burners 2.
  • 3 is an opening for filling in fresh material and 3' is a cover forthe said opening.
  • 4 designates the outlet of the furnace with which, cooperates a plug 5 which is adapted to be raised and lowered for regulating the quantity of material discharged through the outlet.
  • the outlet mouth 4 is surrounded by a rim 6.
  • the annular space between the mouth 4 and rim 6 is designed to be heated by gas flames or the like for regulating the temperature of the glass or slag discharged through the mouth.
  • the space below the outlet 4 is enclosed by annular guard walls 1 and 8 Which reduce the outward radiation and avoid premature cooling of the down flowing mass.
  • a narrow gap 9 is left between the two walls 7 and 8.
  • centrifuging disc ID Arranged below November is, 1931, Serial No. 575,358 Germany November 29, 1930 the outlet 4 at a predetermined distance therefrom is a centrifuging disc ID.
  • This disc consists of a circular plate ll' of a suitable, preferably refractory material and of a metal ring .or casing I2 holding and'encircling the plate II in such a manner'as to prevent breaking of the latter due to the high number of revolutions.
  • the disc in is mounted on a shaft l3 which has the required high speed imparted to it from an electromotor or other source of power through a pulley l4 and belt i5 or any other suitable drive.
  • the upper edge of the wall 8 lies substantially on the same level as the top surface of the centrifuging disc I 0, so that the glass or slag particles which are too heavy will be thrown over and beyond the said edge into the gap 9. They are thus separated from the fibers or threads which have the prescribed weight.
  • the particles entering the gap 9 fall into a collecting gutter Hi from which they can be returned to the melting furnace I.
  • the liquid mass flowing out of the mouth 4 is thrown off the disc in horizontal direction forming a kind of cloud of thin threads which sinks down between the disc l0 and the guard wall 8.
  • This sinking mass constantly increased by the succeeding fresh threads surrounds the shaft I3 as a jacket-like envelope which deposits on an inclined bottom plate IL
  • the material is projected from the disc at points angularly spaced around the axis of rotation of the disc and during the formation of the fibers one end of each fiber is anchored to the disc.
  • the fibrous envelope is continuously or intermittently severed by means of cutting shears l8, which may be operated mechanically, and then glides down over the inclined bottom II to a winding device, not shown.
  • the fibrous web produced by the cutting corresponds in width to the circumference of the fibrous Jacket formed about the disc l0 and shaft l3.
  • the thickness of the fibers can be regulated in various ways, such as by working with more or less high temperatures of the liquid mass, by changin the distance between the disc Ill and the mouth 4 or by controlling the quantity of liquid mass discharged through the outlet 4.
  • a device for producing fibers from molten glass, slag and the like meltable material comprising a receptacle for molten material, an outlet in the receptacle wherethrough to discharge a stream of molten material, a rotatable solid body whereon to deliver the stream of molten material, means for imparting a high rotary speed to the said body, and means for directing a circular downward current of air around said body substantially parallel to the axis of rotation of the same.
  • a device for producing fibers from molten glass, slag and the like material comprising a melting furnace for the material, an outlet in the bottom of the furnace wherethrough to discharge a continuous thin stream of molten mate-- rial, a circular disc at a distance below this outlet whereon to deliver the stream of molten material, an annular air nozzle around the said outlet for directing a circular current of air parallel to the stream of molten material in spaced relation thereto and past the circumference of the said disc, and means for imparting a high rotary speed to the disc.
  • a device for producing fibers from molten glass, slag and the like meltable material comprising a melting furnace for the material, an outlet in the bottom of the furnace wherethrough to discharge a continuous thin stream of molten material, a horizontally disposed circular disc below this outlet whereon to deliver the stream of molten material, means for imparting a high rotary speed to the disc, guard walls about the path of the stream and the. rotating disc in spaced relation thereto, an annular gap in the guard walls at substantially the same level as the top surface of the rotating disc, and means for cutting the fibers as they sink down from the disc about the same in the space defined by the guard walls.
  • a device for producing fibers from molten glass, slag and the like meltable material comprising a melting furnace for the material, an 5 outlet in the bottom of the'furnace wherethrough to discharge a continuous thin stream of molten material, a horizontally disposed circular disc below this outlet whereon to deliver the stream of molten material, means for imparting a high rotary speed to the disc, guard walls about the path of the stream and the rotating disc in spaced relation thereto, an annular gap in the guard walls at substantially the same level as the top surface cf the rotating disc, an annular 15 air nozzle above the disc opening downwardly for directing a current of air around the disc substantially parallel to the axis of rotation of the same, and means for cutting the fibers as they move downwardly away from the disc.
  • the combination'with means for-projecting horizontally from a center fibers of vitreous material, and means fordirecting a current of air downwardly around such center and across the path of the fibers.
  • the hereinbefore described method of producing fibers from a material having no definite melting point but having a definite range of 45 softening which comprises flowing a stream of molten glass or slag, onto a member rotating horizontally, projecting the material from the member and thereby forming fibers therefrom anchored to the member at points angularly spaced around the axis of rotation of the memher by the centrifugal force due to the rotation of the member, and maintaining the material while being projected at a temperature sufiiciently high to give the material a viscosity suitable for the formation of the fibers from the projected material under the forces acting thereon.
