Definitions

  • Our present invention relates to the art of manufacturing artificial threads.
  • Figs. 1 and la illustrate the spinning process
  • Figs. 2. 3 and 4 show the manner in which the thread is deposited
  • Figs. 5 and 6 show conventional view of a finished package or cake.
  • Fig. 7 is a detailed vertical cross-sectional view of a preferred form of the mechanism for imparting movement to table 5 of Fig. 1.
  • the thread i issuing from the nozzle 2 and coagulated in the spinning bath 3 is guided around the galette l and the thread falls from the galette 4 on the plate 5, 10 which performs a rotary movement and an additional movement, for instance a reciprocating or an eccentric movement.
  • the ratio between the period of the rotary movement and the period of the additional movement must be so 15 adjusted that the layers of threads deposited on the plate form a regular system of crossings in which each thread has its determined posi-' tion. It is particularly advantageous to wind the threads in such a manner that the windings lie 20 closely side by side at a distance of about 2 to 5 mm. from each other.
  • FIG. 3 shows the form of the windings which are deposited closely to each other and are helically piled up to form the cake. Under these conditions the layers of 25 thread form a body occupying .a minimum of space and the cake being therefore very solid.
  • the package of threads conserving its form in the usual treatment with liquid is obtained according to the present inven- 30 tion by a method of winding the threads so as to save space.
  • Fig. 4 shows for instance, diagrammatically the crossing of the thread in one layer. This figure has been obtained-by covering with a paper a rotating plate to which an 35 additional reciprocating movement has been imparted by a planetary gear and pressing a writing device, for instance, a pencil against the paper.
  • a planetary gearing for imparting motion to the spinning box 40 I is represented on a larger scale in Fig. 'I.
  • the shaft ll drives the shaft I! through the gear wheels It and I4.
  • Wheel ll has an eccentricaily mounted bushing IS in which rotates the planetary shaft it.
  • On top of this shaft there 45 is mounted the revolving plate (spinning box) 5.
  • a toothed wheel II which engages a stationary toothed wheel ll carried by the base plate I.
  • ll rotates by 50 gearing with II, and it and i turn on the axis of it. This rotation is the main movement, whereas the rotation on the axis of ii and I2 constitutes the additional circular movement.
  • the receiving member for the threads in sim- 15 ple cases, is constructed in the form of a level, plate-shaped disk. There may, however, also be employed a conical or otherwise suitably profiled disk. Finally there may also be used a spinning box of any suitable size.
  • the first condition is that the additional'movement of the plate must not be too quick.
  • the additional movement corresponds approximately with two revolutions of the plate that is to say one reciprocation must cur on somewhat more or less than two revolutions of the plate in which case the thread is deposited on the plate in double loops as shown in Fig. 2. If one reciprocating would occur on exactly one revolution or a whole number of revolutions an unserviceable cake or no cake at all is.
  • the second condition which must be considered for the production .of an lmobjectionable package of threads, is to stabilize the pendulum swing- 60 ings which invariably occur at the freely hang ing part of the thread.
  • the cause for this swinging will now be explained with reference to Fig. 2.
  • the freely hanging thread is received by the plate I at 8, the speed of the thread being' equal 66 to the peripheral speed of point i.
  • the speed of the thread being' equal 66 to the peripheral speed of point i.
  • Points De i I and 8 run at a higher and a lower 70 speed than point G. The thread, therefore, falls on a support which is moved alternately more swiftly and more slowly than the constant speed,
  • the thread is alternately pulled along or pushed I back.
  • the hanging thread therefore, does not move on the path between the points I and I, but.
  • a 725 mm. b: 95 mm. c: 80 mm. d: mm.
  • the plate is rotated at a speed of 112.3 revolutions per minute, and makes reciprocations penminute.
  • the cake obtained after 6 hours spinning had the following dimensions:

Length of thread 20,000 meters Example 2.-When 'spinning'a viscose thread having a titer of 300 deniers at the same speed in a spinning bath of the same specific weight the values of a, b, c and d are the following:
  • the plate is rotated at a speed of 112.3 revolutions per minute, and makes 55 reciprocations per minute.
  • the cake obtained after 6 hours spinning had the following dimensions:
  • the diameter of the cake is determined by the speed at which the plate is rotated and the speed at which the thread is supplied.
  • the mean diameter of the cake (see the dotted line in Fig. 2) is equal to speed at which the thread is supplied ir-number of revolutions of the plate Bobbin spinning 5323: Plate spinning 100 grams 165 grams 500 grams. 0,000 meters 10,000 meters-.-. 30,000 meters.
  • the process according to this invention obviously is not limited to spinning viscose silk as shown in the examples but is adapted for spin- 5 ning spinning solutions according-to the wet spinning process quite generally.
  • a process of producing artificial silk which comprises ejecting a spinning solution into a precipitating bath, guiding the coagulated thread 75 around a rotating galette, causing the thread to fall freely upon a plate, rotating said plate at a speed so that a point of the plate at a subflantial distance from the center of rotation and from the periphery of said plate has the same peripheral velocity as said galette, giving the plate an additional reciprocating movement so that at most one reciprocation occurs on half a revolution of the plate and adjusting the free length of the thread between the point at which the thread leaves the galette and the point at which the thread falls on the rotating plate so that the natural vibrations of the thread are in resonance with the reciprocating movement, whereby a cake which needs no support is obtained.
  • a process of producing artificial silk which comprises ejecting a spinning solution into a precipitating bath, guiding the coagulated thread around a rotating galette, causing the thread to fall freely upon a' plate, rotating said plate at a speed so that a point of the plate at a substantial distance from the center of rotation and 'that the natural vibrations of the thread are in resonance with the reciprocating movement, whereby a cake which needs no support is obtained.
  • An annular self-supporting package of artificial threads comprising double loops of thread helically arranged around an inner free space
  • the free space being inside both loops and the center of curvature of the loops appearing always concave when viewed from the center of the cake, said package having a density in the dry state of placed from the next, and the loops following each other to form one layer lying in substantially the same plane at a right angle to the axis of the annulum, said package being substantially identical with that produced by the process of claim 1.
  • a device for spinning artificial silk thread and assembling the spun thread into a package which comprises a spinning nozzle, a galette for drawing oil a thread emanating from said spinning nozzle, a receiving member for collecting the thread delivered by said galette, and means for assembling the thread upon said receiving member in the form of a self-supporting winding, said assembling means including means for rotating the receiving member in a plane normal to the axle of said receiving member and means for imparting to the receiving member an additional reciprocating movement so that at most one reciprocation occurs during a half revolution of the receiving member, in the plane of the threadreceiving surface thereof, the receiving member being arranged at a distance from the galette such that the natural vibrations'of the thread falling on said receiving member are in resonance with the reciprocatory movement of said receiving member.
  • a device for spinning artificial silk thread and assembling the .spun thread into a package as defined in claim 4, characterized in that the reciprocating movement is imparted by reciprocating means.
  • each loop being slightly dis- 7 which comprises a spinning nozzle, a galette for 10 surface thereof, the receiving member being arranged at a distance from the galette such that the natural vibrations of the thread falling on said receiving member are in resonance with the cyclic movement of said receiving member.
  • An annular self-supporting package of artiilcial threads comprising double loops of thread helically arranged around an inner free space, the free space being inside both loops and the center oi curvature of the loops appearing always concave when viewed from the center of the package, said package having a density in the dry state of 0.2 to 0.5 grams per 0. c. and comprising 20,000,meters of the washed and dried thread in a volume of about 6 c. c. multiplied by the titreof the fiber, each loop being slightly displaced from the next and the loops following each other to form one layer lying in substantially the same plane at a right angle to the axis of the annulum. said package being substantially identical with that produced by the process of claim 1.
