Definitions

  • the gaseous medium easily movable'and consequently easily set into strong eddying motion, has for eifect that the thread is drawn into the apparatus with at the same time the minimum amount of damage to the surface of the fiber, when a very marked curling efiect having an extraordinarily large number 01' spi- 'rals is produced, which curling is very durable, since the gaseous medium does not stretch the fibers after their withdrawal from the eddying zone, as the liquid medium tends to do, butv can even under certain circumstances, by the evaporation of a portion of the liquid attaching to the thread, produce a fixing of the curls already formed.
  • the apparatus for carrying out the process is of very simple construction. Embodiments by current of air coagulating the spinning solution.
  • Figure 5 shows diagrammatically the interposing of the thread curling device in a known process of production
  • Figure- 6 shows the thread curling device in combination with a thread cutting device
  • Figure 7 shows the thread curling device in combination with a modified thread cutting device
  • Figure 8 shows a modified construction of the cutting plate represented in Figure '1.
  • a indicates a tube oi. glass, metal or rubber adapted for thecarrying through 'of the still plastic fiber, and which at its upper 15 end is suitably provided with an opened out part b, which serves to take the ejector-like inset c and has a lateral projection d for the supply of the gaseous medium.
  • the projection d the supply of the gaseous 20 medium instead of being directed radially to the centre of the casing-as in Figures 1 and 4-can also take place tangentially-as in Figures 2 and 3, or in any other direction-whereby theeddy current arising obtains a more or-less strongly pronounced rotary direction.
  • Such a twisting eifect can be attained or amplified in the eddy current by the fitting in of a helically shaped guide piece e ( Figure 4) which is here fitted in the part of the tube a connecting on to the 30 widened out part b.
  • the thread curling device is preferably made so as to be easily taken apart by suitable screw thread connection of the most important parts.
  • V Figure 5 shows the interposition, easily understood, of the device a according to the invention in one of the usual processes for the production of artificial threads.
  • the thread issuing from the spinning nozzle g is delivered over the guide roller h to the thread curling device a, which it 40.
  • curled thread 'i leaves as the curled thread 'i, either to be led in known manner after treatment in a hardening bath p,-to a winding device, or to be further treated in any desired manner.
  • a special advantage of this curling device is 45 that in consequence of its peculiar and extremely simple construction it is very well adapted for the direct production of short stapled artificial fibrous material (staple fibers), since it can be combined with a suitable cutting device into a homogeneous aggregate, as is shown in the embodiments by way of example in Figures 6 and 7.
  • the tubes 0 arranged in a circle or in a row and serving for the guidance of the curled fibrous material are interrupted with the formation of a narrow gap k (for the sake of clearness, shown on the drawings with the width somewhat exaggerated); a cutting too1in Figure 6 a rotating knife I, in Figure 7 a reciprocating set of knives or the like (m1,mz,ma,m4. then cuts up into short pieces or staples the threads carried, under the influence of the gaseous medium blown through, into the lower tube projection, the length of which staples is determined in known manner by the ratio of the speed of the thread supply to the number of cuts per unit of time.
  • the thread so out can also be carried directly into a hardening bath.
  • Figure 8 finally shows in elevation a cutting tool similar to that shown in Figure 7, in which instead of the knives combined into a set, only a single cutting plate n provided with a series of openings 0 is used which, on the reciprocal movement thereof eflfects the cutting of the threads by the knife-sharp edges of the openings 0.
  • Apparatus for imparting a curled form to artificial threads during their manufacture comprising a tube adapted for the carrying through of a freshly coagulated and still plastic artificial thread, provided with an ejector-like opening at one end, a lateral inlet for the introduction of a current of gaseous medium and an internal helically-shaped guide piece adapted to impart a rotary motion to the gaseous current.
  • Apparatus for the production of curled artificial staple fibers from freshly coagulated artificial threads comprising a tube provided with a substantially conical opening at one end for receiving the still plastic thread, means for conveying said thread therethrough and a moving cutting tool at the other and adapted to cut the thread into definite staple lengths as it passes through the tube, said tube being provided with a lateral inlet for introducing a gaseous medium and an internal helical guide adapted to cause the gaseous medium to rotate around the thread as it passes through the tube.”
