Definitions

  • the present invent-ion relates to apparatus for the manufacture of artificial silk according to the stretching-spinning process and has for its object an improvement upon I the apparatus disclosed in the United States.
  • Another object is to provide means whereby air bubbles contained in the water .bath are intercepted and prevented from reaching the spinning nozzle where they could detrimentally affect the spinning operation.
  • Fig. 1 is a more or less diagrammatic perspective view of an apparatus embodying the invention; and Fig. 2 a similar view of the most important detail thereof.
  • (1 represents a spinning cylinder containing at the top the spinning nozzle 6.
  • the spinning tube 0 is centrally disposed below the nozzle and extends through the bottom of the cylinder.
  • At the top and bottom are inlets f and f respectively, for the spinning bath liquid.
  • the apparatus thus far described is part of the prior art.
  • the principal novel feature is the umbrella-shaped hood (1 near the upper end of the spinning tube a. This hood is instrumental in” inhibiting the formation of whirls in the spinning liquid.
  • the tube 0 is preferably provided with a perforation e allowing the entrapped air to be drawn off by the aspirating action of the downward stream in the tube 0.
  • the cold water is introduced through the inlet f preferably through a funnel 9 converging upwardly toward the tube a defining therewith a narrow annular space through which the water is projected upwardly against the hood d as a batlie.
  • the water is thus forced around the hood while the air is collected under the hood and may be readily drawn out as mentioned.
  • the size of the hood (1 is advantageously made to fitthe spinning apparatus and care should be taken not to make it too small.
  • Apparatus according to claim 1 including an upwardly converging funnel 'sur- 66 rounding the spinning tube and cooperating with the inlet at the bottom to direct the liquid entering therethrough against the said hood.
