Definitions

  • My invention relates to a method and an apparatus for simultaneously spinning and twisting artificial threads by means of a revolving nozzle, whereby rotation is imparted to the 5 thread from its starting point, i. e., from the spinning nozzle, the speed employed therefor not being restricted to any greater extent than those at which the prior centrifugal spinning pots operate.
  • the advantages of the novel spinning method not only lie in considerable savings as compared to the methods hitherto known for manufacturing.
  • the pot may be completely filled up by providing it with a cover which has an aperture only at the point where "5 the axis of rotation passes, in which aperture a stationary tube designed in the form of a funnel is inserted, the tube being kept filled with the precipitant up to acertain level and the spun thread being drawn therethrough in the upward l0 direction.
  • the precipitant consequently, consists of a revolving portion (in the interior of the pot) and of a stationary portion (within the funnel tube) one portion passing into the other.
  • Fig. 1 shows one form of the invention employed in connection with the novel spinning method and in which the apparatus is arranged so as to facilitate its tending.
  • the spindle A carries the spinning nozzle B- from which a number of filaments issue as shown, and to be spun into a thread and the pot C and is provided with a central bore for feeding the liquid or viscous spinning material.
  • 7 cover D which may be readily detachably held therein by means of a simple round rubber ring packing which forms at the same time a tight jointbetween cover and pot rim.
  • the tube of afunnel G which is so arranged that it may be raised and pivoted by means of a device H, is inserted in the aperture F arranged in the cover D concentric with the axis of rotation, the funnel tube being stationary in contradistinction to the rotating pot C and cover D.
  • a packing J secured to the funnel tube prevents the precipitant from escaping through the cover aperture F.
  • a thread guide K is arrangediion the under side of cover D and consists .substantially of three bent rods. Two of these rods the This pot is closed by the 40V 7 Such an arrangement is shown in Figure 2.
  • precipitant is supplied through a conduit M to a the stationary funnel Gr and is discharged through bottom perforations L provided in the revolving pot C.
  • the above-described pot to the human hand the spinning of the material, issuing from the pot at rest, onto a lowspeed auxiliary taking up device, from which the thread indicated in Fig. 1 by the vertical arrowed line, after passing it through the cover and funnel and after initiating the rotation and after i attainment of full speed, may be spun onto the winding apparatus at the full take up speed.
  • the arrangement shown in Figure l- may be modified by providing a tube within the rotary container which tubeis concentric with and surrounds the nozzle so that the latter discharges the viscous material into a hollow cylinder of comparatively small diameter,
  • the precipitation liquid which is supplied from the stationary funnel is fed from the top of the cylinder to the spinning nozzle.
  • A designates the driving motor. Its
  • the spinning nozzle B At the upper end of the hollow shaft is mounted the spinning nozzle B.
  • the rotary vessel C is fixed on shaft A and rotates with it. This vessel is closed by the cover D which is provided with discharge openings L and tightened at its rim against the vessel rim by means of packing E.
  • Vessel C contains a cylinder F of comparatively small diameter which is fixed 0n thebottom of vessel C and which surrounds at its lower portion the spinning nozzle B so that the whole combination rotates on the axis of shaft A,
  • the filling container G is connected with cylinder F by means of a flexible hose coupling J.
  • this coupling permits cylinder F .to revolve in it, yet this coupling bears with suiiicient tightness on the upper end of the cylinder so as to prevent leakage of fluid from the joint.
  • the rotary vessel C is surrounded by a stationary jacket H which carries the stationary vessel G at its upper end.
  • K is athread guide which is mounted near the upper end within cylinder F, and R represents a supplyline terminating above vessel G for supplying the precipitation liquid. This liquid in filling vessel G passes through coupling J into cylinder F, filling the latter completely.
  • the device is started for instance by inserting a rod from above (not shown here), until'the rod end reaches the vicinity of'nozzle B where the viscous material is discharged.
  • the rod has embodiment permits when adapting the dimensions of the spinningv preferably a roughened end so that the filaments issuing from the nozzle adhere. to the rod and g in this manner they can be pulled. up outside of vessel G whence they are led onto a roll.
  • the rotating elements can be more easily tightened against the stationary elements, because the radii of the sliding surfaces are comparatively small.
  • the liquid which acts upon the thread and the filaments is confined within cylinder F, and since this cylinder is of comparatively small diameter, it becomes possible to bring the spinning device much quicker to full speed (considering that at the start vessel C is stillempty).
  • the filaments are least stressed by any liquid movement at'the point where they emanate from the nozzle and where they are most sensitive. Further on, the stress upon the filaments created by the resistance of the liquid is distributed over a comparatively great lengthpractically the entire cylinder lengthso that undue local stress, which may easily cause the breaking of a filament, is thereby entirely avoided.
  • the inner wall of cylinder F may be provided with flutes or ridges for a certain portion of the cylinder length so-as to facilitate the'rotation of the liquid within. These ridges or flutes are designated with 'V in Figure 2.
