Definitions

  • the method of treating the fibers, according to the invention thus opensup new fields of applications for those natural raw materials
  • spreading, smoothing, stroking and the like appliances are used for distributing the cellulose in its liquid raw state around the fiber, which at the point of contact 40 are movable transversely to the fiber or are stationary and the fiber movable transversly to them.
  • the crosssection of the passage through the nomle or other coating device is made variable inaccordance with the present invention, the resilient or elastic portions of the coatingdevice are able j to give way when forced aside by the irregularities of the fibers or threads, so that no inadmissible stresses develop in the fiber or the thread and it is at the same time possible to adapt the coating, as regards the thickness, for instance,
  • At least one of said strickling members comprises a pivoted lever which lever is arranged for movement in a path removing each point of its contacting surface away from the path of travel of the filament as soon as any thickening of the filament passes the contact point.
  • Resilient preferably regulable means are provided for urging the lever to cause the portions which engage the filament to lightly touch the filament, and to cause them to constantly follow any unevenness of the moving filament.
  • the point of contact of the pivoted lever with the filament is arranged so remote from the normal line drawn from the pivot to the path of movement or the filament, so that each point of the contacting lever surface is moved away from-the path of travel of the filament.
  • any of the well-known cellulose derivatives in liquid condition such as viscose, will serve as a coating which then as soonas the fiber is satu-
  • this passage throug the coagulation bath is efi'ected in such a wa that the coagulation has taken place at least superficially prior to the fiber touching another solid body, such as ui rollers, thread guides or the like.
  • the coagulation liquid or solution is applied. tangentially tothe direction of travel behind the free or floating length of the fiber, as will be described in greater detail further on.
  • Fig. 1 shows in vertical section and in diagrammatic fashion, a receptacle containing a cellulosic solution in conjunction with a coating, strickling or stroking device.
  • Fig. 2 illustrates a sectional elevation, a nozzle constructed according to this invention.
  • Figs. 3 and 4. show in side elevation and in plan another modification of a strickling device.
  • Figs. 5 and 6 show in side elevation and in plan respectively, another form of the invention.
  • Figs. '7 and 8 show in side elevation and in plan respectively, still a further form of the invention.
  • Figs. 9 and 10 are a side elevation and plan respectively of another form of the invention.
  • Figs. 11 and 12 show two examples of an arrangement of a primary bath vessel, a coagulating bath vessel and means for passing the threadto be treated from one bath to the other without touching any rigid part other than the stricklingdevice.
  • ll indicates a receptacle containing the cellulose in its liquid primary state, for instance in the form of viscose.
  • the thread l3 to be coated is unwound from a reel l4, passed over a guide roller l5 through the bath l2 and issues from the bath at a strickling coating, applying or spreading device lG.
  • Some designs of this device are, by way of example, illustrated in Figs. 2 to 15 of the drawings.

  • the spreading or stroking device consists of members 30, 3

  • These members are preferably so arranged, that under normal conditions they are in stable equilibrium under the action of the retrieving forces, i. e. the weights 4
  • the operative faces of the strickling or coating device are preferably so designed that they gradually converge into a slit.
  • the slit may be uniform across the entire width of the coating device, but it may also, as shown in Fig. 6, be provided with recesses 46 at the point of exit of the fiber or thread.
  • Figs. 7 and 8 illustrate a further con struction of the coating device.
  • the bodies tapering into nozzles consist of two parts 50, 5
  • One part comprises a mouthpiece 52 adapted to rock around a hinge pin 53, which under the action of the.spring 54 is pressed against the fiber or thread l3 by means of a system of lever 55, 56 and adapts its position to the irregularities of the cross-section of the thread.
  • the liquid will first surround the thread with a flattened crosssection which, however, withregard to the free length of thread located behind the point of issue from the coating device, contracts into a uniformly roundcross-section.
  • This uniform application of the cellulose solution around the fiber or threads may be adjusted by suitably setting the working speed, controlling the viscosity of the celluloid solution, the pressure applied to the point of exit from the coating device and so on.
  • rods, rollers, drums and the like over which the fiber is guided along a sinuous path may also serve as a spreading or stroking device.
  • rollers 88, 33 are held in jaw-like structures 90, 9

  • the coating devices will be so constructed that they do not change the direction of travel of the fibers or the thread at all or only an inconsiderable extent; In this way it is avoided that the cellulose solution is entirely or partly stripped aocaseo or wiped off the thread on the deflected side and the equalization of thecellulose solution around the periphery of the thread affected thereby.
  • Figs. 11 and 12 ofthe drawings two examples are shown which illustrate how the fiber, thread or tape passes from the primary bath of viscose, for instance, and the coating device into the further treatment baths.
  • a free or floating length of thread is provided hehind the coating device or betweenthe coating devices at H0, in order to enable the primary liquid to distribute itself uniformly around the thread.
  • the coating is according toa further feature of the invention immediately behind the free length throughout or superficially coagulated before the fiber, the thread or band comes in contact with another solid body, for instance a guide roller or thread guide or the like.
  • the coagulation -liquid is applied to the fiber or the like tangentially in the direction of travel.
  • the fiber or thread to be treated enters an annular nozzle Ill designed as mouthpiece of a vessel H2.
  • The, vessel H2 contains, for instance in an annularly shapedextension directed jdown-' wards from the vessel, for example, a store of liquid, which is fed to the nozzle under pressure through the pipe 4, a suitable pumping device 5, and pipe ill.
  • the nozzle sprays or squirts the coagulation liquid around the thread.
  • the coating coagulates at first only superficially, so that it becomes indifferent'to contact with further solid bodies, such as guide rollers and the like.
  • the coagulation liquid returns through the intermediate member ll6 into the vessel i l2, so that the coagulation liquid describes a closed cycle.
  • the treated thread 0 is in the vessel 8 i2 subjected to further. treatment of the coagulation liquid and then passes, in a manner not shown in the drawings, into further finishing baths, identical with those customary in the manufacture of cellulose products.
  • the thread is then wound on to the reel or bobbin 120.
  • the coagulation liquid is behind the free length or floating portion H0 applied to the fiber or thread or band in the form of a. free jet.
