Definitions

  • One object of the present invention is to provide a method which will give the threads running from the spinning nozzle to the collecting device, such as spool or spinning centrifuge, a certain amount of stretch, and change the intensity of stretch from the beginning to'the end of the winding process.
  • Another object of the present invention is a method for giving theireshly spun thread on its way between the spinning nozzle and the colleeting device a predetermined stretch, increasing the amount of stretch from the beginning to the end of the winding process and providing means copper-process and the like it is known that the thread packages obtained, particularly bobbin packages, but also cakes produced in the so called spinning centrifuges, show. variously strong the bobbin packages and at the interior portions 'of the centrifugal packagesl In order to compensate these various aflinities to dyestufis quite a numberof suggestions have been made, which,
  • Fig. 1 shows diagrammatically the spinning arrangement for the so-called spool-spinningprocess
  • Fig.2 shows also the spinning arrangement for tional friction roller
  • Fig. 3 shows the spinning arrangement for the centrifuge-process.
  • Fig. 1 the thread rises from the spinning nozzle d situated in the spinning bath on to the interposed, positively driven drawingoff roller R and from there it reaches via the transport roller r and through the traverse guide F the spinning bobbin S.
  • the bobbin S is drivenin a known manner in such a way-that the draw-- off speed of the thread remains approximately
  • the positiveiy driven and slip-free workingdrawing-bfi roller R is driven in such a; way that it receives an increasingly slower draw-off speed in the course of the winding process.
  • the drawing-off roller which is interposed and driven positively and working at an increasingly diminishing draw-01f speed, is a marked R1 in this case.
  • the positively driven winding member comprises the positively driven delivery godet Ra, which per sevis always present, and the spinning pot T.
  • the prepositioned godet which is positively driven and works at an increasingly diminishing transport speed during the. spinning process is here marked R1.
  • aovaaoe prises extruding a cellulosic solution to form a thread, giving the thread different linear speeds at predetermined spaced points in its path of travel by passing the same after formation of the with the resultant increasing elongation of the threadwhile it is being wound on the bobbin whereby objectionable characteristics. resulting from contraction are avoided.
