OF BLOOMFIELD, NEW JERSEY Application filed June20,
The present invention relates to a method of producing artificial silk or the like, and has for its main object and feature the production of a thread-like materialof a more uniform character than has heretofore been possible, from a synthetic fluid material.
In the accompanying drawings is shown a preferred form of apparatus by means of zvhich the method may be carried into prac- In said drawings: I
Fig. 1 is a somewhat diagrammatic view of the more important elements of a rayon spinning machine; 1 r k section, showing more particularly the means for actuating the thread-guide;
Fig. 3 is a diagrammatic view of a typical lay or winding of the thread-like material on a spool;
Fig. 4 is a diagrammatic View showing the "step of washing and dyeing; and
F1g. 5 is a view similar to Fig. 3 but showin the effect'of drying the material. In the production of artificial silk or the like, the thread-like material issues from a. spinnerette immersedin a bath, and the thus newly-formed or green thread-like material passes then directly to a win ding mechanism consisting essentially of a thread-guide and a rotatable spool, said elements having a transverse movement one with relation to the other so that the thread-like material is wound cross-wise into a number of superposed series of convolutions first in one and then in the other direction.
One difliculty heretofore encountered in the art is a tendency toward a lack ofuniformity in character of the thread-like material, which tendency appears to be caused by the fact that the material during the various processes is subjected to unequal strains on different portions thereof or to too severe strains. It must be borne in mind that the thread-like material is newly formedpr strains can be caused by shrinkage due to the drying or finishing of the material; or, they may be caused by excessive pull of the spool 1930. Serial No. 462,493.
or take-up device brought about by the constantly increasing diameter. of the spool due to accumulation of material thereon because, as the spool increases in diameter, more-and more thread will be wound per revolution of the spool.
The invention consists essentlally in laying spool. Dueto the slack in the convolutions,
numerous interstices are formed in the material so that, during the washing or washing and dyeing process, the liquid will penetrate the spool more readily than would otherwise be the case thereby reducing, very materially, the time necessary to complete the process. In conjunction with the above, the invention further consists in supplying the synthetic 'fluid, from which the threadlike material is formed, at a rate that is proportional to the speed of the take-up of the material, and winding the newly-formed or green thread-like material at a speed proportional to the rate of supply of said fluid material. In this way gradual attenuation in the formation of the thread-like material is prevented and, consequently, the slack convolutions above referred to will consist of thread-like material of substantially uniform character. 1 represents a pump of any suitablecharacter to deliver synthetic fluid material supplied by duct 2 to spinnerette a in setting bath 3 where the thread, or threads, 4, or the like, is formed, said thread-like material being wound on rotatable. spool 5 as it emerges from the bath. 6 indicates a threadguide to lay the thread on the spool. In Fig. 3 is shown diagrammaticallya typical lay of thethread according to this inventlon. As there shown thread 4 is laid in a series of convolutions I) crosswise first in one and then in the other direction, said series being superposed. Convolutions b are provided with a slack 0 which, in the exemplification shown,'takes' the form of undulations d in helical convolutions b. It will be apparent that the slack may be produced by a relative movement of the spool and thread guide, one with relation to the other. This can be obtained by moving both the spool and the thread-guide, or it can be produced by moving one of these with respect to the other. In the present exemplification of the invention, the following construction is used. The spool is rotated by gears 18 and 19, and thread uide 6 is mounted on a reciprocatory bar 60 slidable in bearings 61. 62 is a rotating cam on shaft 63, on which shaft is a'guide 64 that moves a reciprocatory rack-member 65 actuated by cam rolls .66 that engage cam 62. Said rack'member is provided with teeth at its upper end that engage a pinion 67 on shaft 68, and on the latter shaft is mounted another pinion 69 that engages a rack 70 on bar 60. Rotation of cam 62 therefore causes a back and forth movement of bar 60 and hence of thread-guide 6. Said thread-guide is mounted to rock or oscillate on center 71 of bar 60, this movement being accomplished by lever 72 and link 73, pivotally connected at 74, said lever 72 also being pivotally connected to crank pin 75 of shaft 76. Rotation of crank pin 75 vibrates the thread guide. Shaft 76 is mounted on-a bracket 77, carried by bar 60, and said shaft is rotated by any suitable me ans.
The means to coordinate the speed at which the thread is being wound and the rate at which the synthetic fluid material is being supplied will now be described. This coordination may be brought about by varying the speed relation of the spool and pump. The
speed of the spool can be gradually diminished as the diameter of the wound material increases, or the rate of delivery of the synthetic fluid material can be increased as the diameter of the wound material increases, and thelatter construction is here followed. Shaf t'S, on which the spool is mounted, is driven at a substantially constant speed from mot r 9, the transmission members being here as follows: sprocket wheel 10, chain 11, sprocket wheel'12, shaft 13, sprocket wheel 14,chain 15, sprocket wheel 16, stub shaft 17,
Motion may be imparted to shaft 63 of cam 62 by suitably proportioned gearing, indicated diagrammatically at 78 and deriving its power from shaft 13. 7
It will now be understood that the newlyformed or green thread is laid as indicated by way of example in Fig. 3. After a sufiicient quantity of; thread-like material has been wound on said spool, it is' removed from the spinning machine and placed with other spools in a washing machine 79 (Fig. 4) where the washing liquid is drawn through the interstices into the interior of the spool in a manner well understood.
After the washing operation is finished, the spool may be subjected to a dyeing and other operations. Whatever the character of these, said spool is finally subjected to a finishing operation, which may be simply the step of drying. During this latter process, the thread-like material shrinks, as indicated diagrammatically in Fig. 5, said shrinkage being within the amplitude of the slack of the convolutions so that no unequal strain is placed on different portions of the material.
