Definitions

  • An object of the invention is the provision of an apparatus reducing substantially the required space to satisfy the great demand which has sprung up within the last few years in factories making artificial spinning fibers when operating according to the methods described in U. S. Patent No. 1,971,627 or- French Patent 625,049.
  • Still another object is the saving of large quantitles of liquids required for .the spinning baths.
  • FIG. 1 shows diagrammatically a device for manufacturing artificial spinning fibers according to this invention
  • Fig. 2 shows diagrammatically a modified device for manufacturing artificial silk according to this invention
  • FIG. 3 shows diagrammatically afurther modification of a device according to this invention
  • Fig. 4 shows an arrangement for pressing a sliver according to this invention with a channel under the rollers for guiding away the liquid and roof-shaped pieces of sheet metal for leading away the liquid flowing through the perforated $5 conveyer band,
  • Fig. 5 shows the manner in which the sliver is lifted from the conveyer band
  • Fig. 6 shows a further modification of a device according to this invention
  • m Fig. '7 shows a roller provided with bosses for imparting a profile to the sliver
  • Fig. 8 shows the arrangement of tubes near a guiding roller for treating the under side of the sliver
  • Fig. 9 shows the arrangement of a driven perforated hollow roller over which the sliver passesand a' tube arranged inside the roller for spraying liquid against the under side of the sliver.
  • the endless fiber band coming from the spinning nozzles is out before or after having been deacidified and floated with water through a loosening device on a perforated conveyer band.
  • the fibers are deposited on this conveyer band in the form of a sliver. In this form the fibers are subjected to the complete after-treatment by irriga tion.
  • the conveyer bands must be resistant to the chemicals with which they come into contact; a perforated band of rubberv or resistant sheet -metal may be used or a band of wire gauze or of a textile material may be suitable.
  • One single conveyer band of sufficient length may be used or separate conveyer bands may be used for each different treatment.
  • the irrigation is produced by the known spraying apparatus and is effected over such a length of the conveyer band that the treatment is complete throughout the sliver. Between the different treatments the sliver is squeezed by means of squeezing rollers. The liquid after passing through the sliver flows through the perforated conveyer band'and is collected. Suitable devices may be arranged between the upper and the lower part 'of the fiber band in order to protect the lower part of the conveyer band from the action of the liquids so that the action of the liquids on the band is reduced to the absolute necessary.
  • the conveyer band is subdivided it is preferably arranged so that the sliver is guided upwards to the squeezing rollins and after having passed the squeezing rollers sliver again falls. back on the conveyer band.
  • a pair of squeezing rollers may be arranged in the middle of the; length over whichone treatment lasts.
  • the lower roller of the pair of squeezing rollers may be grooved whereby the band. is made thinner. This furthermore involves the advantage that the liquid more easily flows ofl.
  • a roller provided with bosses may operate against one of the rollers supporting the conveyer band and thus imparts to the silver passing between the two rollers a profile.
  • the sliver may also be passed over a driven perforated hollow roller.
  • a spraying device is arranged for spraying liquid against the under side of the sliver which passes 'over the hollow roller.
  • the freshly produced band 11 consisting of endless individual fibers, is cut or torn, .while still in fresh condition, in a device marked-b and is brought over a bridge piece, for example a moistening trough c, to a watering device (I, for instance such as is described in U. S. Patent I -To. 1,627,037.
  • a watering device I, for instance such as is described in U. S. Patent I -To. 1,627,037.
  • the bundle of fibers is opened up and, if desired with the use of a second watering trough is spread in the form of a sliver uniformly on the whole working breadth of the conveyer band e.
  • a second watering trough is spread in the form of a sliver uniformly on the whole working breadth of the conveyer band e.
  • only one conveyer band with the necessary appendages is shown for the whole after-treatment.
  • the conveyer band is permeable for liquid and consists either of perforated or. woven material resistant tochemicals.
  • the band is endless and runs on the rollers 1, h, which drive it. Between the rollers 1, ii the band is carried either on a perforated table or, as shown in Fig- 1, on rollers g which are preferably driven. Above the band there are arranged troughs supplied continuously with the chemicals necessary for theafter-treatment and liquids for washing, for instance at h washing occurs, at i treatment with sulfite, at k a second washing, at l a treatment with hydrochloric acid, at m a third washing and at n the treatment with soap solution.
  • the excess of liquid is expressed by a roller in cooperation with the conveyer roller /1.
  • the several liquids used in the treatment run away into receptacles, not shown in the drawings. 1
  • a guide 3 is arranged which may consist of either stationary strips against which the sliver slides with the smallest pos-.
  • Fig. 2 is shown a similar apparatus in which the conveyer band is subdivided, the separate bands e, ei, e2, etc., being preferably inclined, so that'owing to .back flow of the treating liquids against the direction of travel of the bands the liquids are better used.
  • Short transfer bands 8, s1, etc. bridge the distance between one conveyer and the next. These may be perforated and in order to avoid, as far as possible, the transfer of liquid from one conveyer to the next expressing rollers o, 01, 02, etc., oo-operate with the conveyer rollers I, f1, f2, etc.
  • Fig. 3 a modified apparatus for working up the sliver collected on the conveyer band is shown.
  • the squeezing roll- 1 ers oq are mounted above the conveyer band e.
  • the guide 31 of the conveyer band shown in I Fig. 1 has been omitted as being unnecessary if the band is large enough.
  • the sliver is passed on a separate conveyer band for the treatment with soap because in this casenickel wire gauze is used.
  • Fig. 4 shows an arrangement in which a smooth squeezing roller is arranged above a grooved roller. The all er is squeezed between the two rollers and the liquid flowing oil is guided in a collecting vessel by means of a channel arranged below the squeezing rollers. Between the upper and the lower'part of the conveyer band a roof-shaped distribution plate is ar--- ranged which distributes the liquid flowing durconveyer band so that it passes over the lower part of the band and flows directly into the collecting vessel.
  • Fig. 5 is shown how the band is squeezed once more in the middle between the squeezing rollers arranged at the end of'each treatment.
  • Fig. 6 shows an arrangement similar to that shown in Fig. 2 with the difference that the squeezing rollers are mounted so that the band is not pressed by them. After the silver has been pressed it falls back on the next conveyer band.
  • Fig. 7 shows a roller provided with bosses.
  • This roller may be arranged so as to co-operate with one of the supporting rollers as shown in Fig. 3.
  • the sliver receives a profile as a consequence of which the lower strata of the sliver are more intensely treated.
  • the sliver is guided over a hollow perforated roller which is driven.
  • a perforated tube is mounted for spraying liquid through the hollow roller against the lower side of the sliver whereby the effect ing the treatment through the upper part of the of thetreating liquid is considerably increased.
  • Such a hollow roller with a perforated tube mounted inside is shown in Fig. 6 as assisting the washing effect before the sliver is treated with the soap solution.
  • the finished after-treated and squeezed sliver in which the individual flbriles have not varied or have very little varied from their original relative position, is either wound to a roll indicated by r in the drawings or conducted continuously and directly to a mechanical drying device, not shown in the drawings.
  • the artificial fibers After the drying or after the adjustment of the degree of moisture, the artificial fibers, after I they have been opened, show a surprising capacityfor spinning.
  • the process and the apparatus may be used in the manufacture of all wet spun artificial fibers, for instance artificial fibers from ammoniacal copper oxide solution; in the case of copper fiber it is important that the fibers should be cut or torn before the final conversion into cellulose.
  • An apparatus for the continuous production of curled rayon staple fibers comprising a cutting device capable of cutting a bundle or sliver of continuous rayon filaments, attached thereto a device capable of loosening the staple fiber cuttings and of forming a continuous fleece of fibers, a perforated conveyer band operatively connected therewith so as to receive and forward the continuous fleece, a number of sprinklers mounted above said conveyer band to soak said fleece with a plurality of treating and washing liquids, and squeezing rollers arranged above said conveyer band and between the particular sprinkling devices.
