Definitions

  • the present invention relates to the manufacture of artificial silk and more particularly to a device to be employed in the process of producing artificial threads and the like by the centrifugal method.
  • the number of convolutions of thread being fed into the pot per minute is equal to and the number of convolutions per full stroke of the funnel is equal to
  • the resultant cross-wind ratio passes through such values as 5, 6 and 7 such values being known as simple cross-wind :ratios. this that the cross-wind ratio or the resultant value is the number of convolutions of thread fed into the spinning pot at a given moment during one full stroke of the spinning funnel (the up and down stroke).
  • a distinct diamond shaped pattern can be distinguished within the cake.
  • Such a pattern is formed by the superim:
  • Figure 1 is an elevational view of an improved thread guide funnel having a corrugated or notched mouth at the lower end from which the thread emerges;
  • Figure 2 is a bottom plan view of the funnel shown in Figure 1;
  • Figure 3 is a fragmentary view of a lower portion of a modified funnel
  • Figure 4 exemplifies a lower portion of another modified form of thread guide funnel
  • Figure 5 is a perspective view of the lower portion of a further modified form of funnel.
  • Figure 6 is a side elevational view of the funnel illustrated in Figure 5, which funnel is shown in position within a conventional pot.
  • the numeral l indicates a thread guide funnel utilized in the manufacture of artificial silk according to the centrifugal process. At the lower end of this funnel the peripheral edge surrounding the mouth thereof is formed a series of projections 2 with resultant depressions therebetween.
  • the funnels indicated at l in Figures 1 to 4, inclusive, differ only in that the number of pro jections 2 are varied, i. 'e. in Figure l, eight projections are shown, in Figure 3 two projections are shown, while in Figure 4, four projections are shown.
  • the projections and depressions may be in the form of symmetrical corrugations or, if desired, may be in the shape of saw-teeth 3 as exemplified in Figures 5 and 6.
  • a pot 4 of the general type shown in Figure 6 is used in the op eration of any of the funnels specifically illustrated.
  • This wavy deposition of the thread prevents a number of consecutive convolutions to superimpose upon each other during those periods in the formation of a complete cake when simple cross-wind ratios exist. Accordingly, the cake produced in practicing this invention is more permeable to treat-.- lng liquids, and also the unwinding thereof is enhanced. Although the undulations produced in the thread being collected overcome the foregoing disadvantages, they do not influence the characteristics of the finished thread such as the denier and dye affinity thereof.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having a series of projections and. depressions surrounding the mouth thereof over which the thread is caused to ride as it emerges and is laid up to form a cake within a pot.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having a series of projections conforming to the type of saw-teeth surrounding the mouth thereof over which the thread is caused to ride as it emerges and is laid up to form a cake within a pot, the said saw-teeth projections having edges sloping downwardly in the same direction as the rotation of the pot.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having from two to eight projections and a corresponding number of depressions surrounding the mouth thereof over which the thread is caused to ride as it emerges and is laid up to form a cake within a pot.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having from two to eight saw-teeth projections surrounding the mouth thereof over which the thread is caused to ride as it emerges and is laid up to form a cake within a pot, the said sawteeth projections having edges sloping downwardly in the same direction as the rotation of the pot.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having at least two projections and at least two depressions surrounding the mouth thereof over which the thread is caused toride as it emerges and is laid up to form a. cake within a pot.
  • a spinning funnel for use in the manufacture of artificial silk according to the centrifugal process comprising a hollow body portion having at least two saw-teeth projections surrounding the mouth thereof over which the thread is caused to ride as it emerges'and is laid up to form a cake within a pot, the said saw-teeth projections having edges sloping downwardly in the same direction as the rotation of the pot.
