Definitions

  • This invention relates to the manufacture of artificial silk and more particularly to the spinning of filaments from thick liquids or solutions passed through a cylindrical spinning funnel or vessel depending into a bath and containing a liquid column of precipitating liquor, the chief object being to improve and simplify the machine or apparatus for effecting the stretch spinning 0 of the filaments.
  • the filaments as they emerge from the spinning funnel or vessel are conducted through a combined guide and traversing device adapted to permit of the filaments or threads being treated with acid, water, or other treating liquor flowing in an opposite direction to the travel of the filaments or threads preparatory to winding.
  • Figures 1 and 2 are respectively a sectional side elevation and plan of a combined guide and traversing device according to the invention and adapted for single washing.
  • Figures 3 and 4 are respectively a sectional side elevation and plan of the combined guide and traversing device as adapted for double washing.
  • the combined guide and traversing 'device comprises a triangular shaped member 1, fittedor formed at its narrow end with a notch 2 or other appropriate thread guide and having its base or floor portion provided with transverse ridges or corrugations 3, over which the filament or thread l'passes from the spinning vessel (not shown) and trough 5, to the winding on device or bobbin (not shown).
  • the combined guide and traversing device 1 is mounted on a pipe or tube 6, through which water or other liquid for treating the filament or thread 4 may be supplied through an inlet opening 7, toward the front or narrow end of the member 1, so as to come into contact with the filament or thread 4, passing over the ridges or corrugations 3, towards the rear of the member 1.
  • the washing liquid flows in the opposite direction to the movement of the filament or thread 1, thus bringing said thread 4 into repeated contact with clean liquor.
  • the pipe or tube 6 is reciprocated by any convenient means so as to impart to the devices or members 1, to and fro lateral motion in accordance with the winding of the filaments or threads 4.
  • the member 11 is provided with drain apertures orholes 12 at its rear end, and is fitted to the front wall of the trough 5 by integral slotted side brackets 13.
  • the guide 1 which is reciprocated or constitutes a traversing member for properly delivering the thread or filament to a winding spool or bobbin is of such form that the liquid discharged thereon from the opening 7 will be spread into a thin film-like form as it flows over the ribbed surface.
  • This particular form of guide has been found to be of reat practical importance as it permits of die free escape of ammonia gas and the action of the air on the thread passing over the guide is one which cannot be obtained when the guide is of relatively deep, narrow, channel-like form and through which a considerable volumeof washing liquid flows.
  • the shape of the guide avoids the bending of the thread at sharp angles as the uide is traversed to properly wind the thread upon the winding means.
  • the threads are drawn from the trough at a speed approximately thirty to sixty meters per minute, and when the guides between the trough and winding device are of the form of relatively deep and narrow channels where the thread is immersed in a relatively large volume of liquor, it is very ditlicult to free the threads or filaments from the chemical solutions with which they have been treated and which pass with the threads or filaments from the trough over the lower end of the guide.
  • the guide 11 is provided asshown with a relatively large number of drain apertures adjacent the trou h and further the supply of liquid thereto rom the passage 10 moves as a relatively thin film permitting the free escape of ammonia and also allowing a partial oxidizing of the copper ammonia cellulose by the action of the air.
