Definitions

  • the glass rod tip is heated to the state of spinning plasticity either with small sharp flames or 'by means of electric heating coils.
  • Flame heating has the inconvenience that the necessary streaming speed of the flame finally becomes greater than the mechanical resistance of the tiny forming filament. It has been proposed to heat the spinning tip indirectly, with protection by means of a nozzle, in order to retain the flame wind, but this method involves other inconveniences.
  • Electric heating is boundowing to the heating resistor needed-to a limited minimum extent of the resistors, which extent does not allow for accurate concentration of temperature to the spot at which the filament is spun off the glass rod, so that oscillations in the streaming conditions at the spinning tip have disadvantageous consequences.
  • the locus of spinning that is, of the thermo-viscous formation of a drawing-off filament and of a spinning tip on the glass rod, is separated as a spinning space heated indirectly and screened against the heating space.
  • Heating may be effected by means of any suitable heating source. It is irrelevant whether in that heating space, which is divided from the spinning space, there are employed free or separately incased heating means, vor gaseous, liquid or solid heating means or electricity or a combination thereof. By means of a slit-shaped residual communication 'between the heating and the spinning spaces, enlarging or reducing thereof can serve to create the most favourable conditions for the spinning spot indirectly depending on the heating source. Or else one separates the spinning and and heating spaces completely land creates for the spinning spot the most favourable conditions, by forming the heating space and the spinning space internally land externally with the most rational shapes.
  • Fig. 1 is a vertical cross-sectional View of the device for spinning textile filaments from glass rods, and,
  • Fig. 2 is a top plan view thereof.
  • reference lnumeral 1 designates an insulating body, which is preferably made of refractory material.
  • the insulating body 1 is formed in its longitudinal direction with -a recess which is in communication with the outside at the top by way of a vertical shaft 3 and at the bottom by way of a shaft 4.
  • the recess and the shaft 4 are internally lined with a high-grade ceramic material 5, e. g. porcelain.
  • a vertically displaceable hollow T-shaped moulded body 6 of ceramic material In the longitudinal direction of the moulded body 6 there are provided a set of vertical bores 7, which open down' wards into a through shaft 8 in the moulded body 6.
  • the moulded body 6 is adjusted in its position in the shaft 3 in such a manner that under its bearing surfaces on the insulating body 1 there are positioned plates 9 (e. g. of asbestos) having suitable thickness.
  • plates 9 e. g. of asbestos
  • the moulded member 6 penetrating into the recess, the latter is divided into three spaces.
  • the heating energy which may be of' any nature, whence these spaces are called heating spaces.
  • the space formed by the shaft 8 in the interior of the moulded member 6 represents, together with the shaft 4, the spinning space.
  • the spinning space is in communication with the heating spaces 2 by way of' the aperture 12 ad justable by means of the setting of the moulded mem- 'ber 6.
  • the glass rods 11 are introduced by means of the feeds 10, the rods first entering the shaft 8, wherein they are preheated.
  • the shaft 8 is screened against the heating spaces 2 by the walls of the moulded member 6, so that the glass rods are exposed, while being fed, to steadily increasing heating, until they arrive at the apertures 12 to receive direct heat from the heating spaces 2 and are thus brought to the state of spinning plasticity.
  • a device for spinning textile filaments from glass rods comprising a member including a spinning chamber through which a glass rod is axially moved and wherein the thermo-viscous formation from the glass rod occurs, said member further including a heating chamber in proximity with the spinning chamber and wherein heating energy is directly present, axially aligned liners disposed in the member to separate the spinning charnber from direct -communication with the heating chamber except at the adjacent inner ends of the liners, said liners being axially adjustable relative to each other to adjust the size of a communicating opening between the spinning chamber and the heating chamber at the inner ends of the liners.
  • a device for spining textile filaments from glass rods comprising a member including a spinning chamber through which a glass rod is axially 'moved and wherein the thermo-viscous formation from the glass rod occurs, said member further including a heating chamber in proximity with the spinning chamber and wherein heating energy is directly present, axially aligned liners disposed in the member to separate the spinning chamber from direc-t communication with the heating chamber except at the adjacent inner ends of the liners, one of said liners being axially movable relative to the other to adjust the distance between the inner ends of the liners so as to provide an adjustable communicating opening between the spinning chamber and the heating charnber at the inner ends of the liners.
  • a device for spinning textile filaments from Yglass rods comprising an insulating body having an opening extending completely therethrough and through which a glass rod is axially moved, said openingconstituting a spinning chamber, a pair of liners covering lthe walls 0f the opening, said liners having inner spaced apart ends and being adjustable axially relative to each other to ad justthe spacing between their inner ends, a heating chamber in the body at the inner ends of the liners which are adjustable to provide an adjustable communicating opening between the heating chamber and the spinning charnber.
  • one of the liners has an outer end provided with a lateral flange and 4 removable plates interposed between said flange and the body to control the spacing between the inner ends of the liners.
