  • a staple fi-ber web 1 subjected to a drafting operation at a group of rollers 2a of a drafting arrangement 2 arrives at a liquid applying or introducing device 3 supplied with liquid from a pressure tank or vessel 4.
  • the thus formed sliver or band is removed from this location by means of a pair of calender rollers 5 and delivered to a suitable depositing mechanism 6 eg funnel or trumpet wheel for laying out in a conventional sliver can 6a.
  • the liquid removed by the calender rollers 5 is collected in appropriate receiver vats or collecting troughs '7 and though the agency of a pump 8 and filter 9 is again returned in convenient manner to the pressure tank or vessel 4.
  • the liquid ap plying device 3 of FIGURE 1 essentially embodies a web forming element 10 constructed such to transform the web 1 from a fiat or plane configuration into tubular,
  • the not yet closed sliver or band liquid supply means here shown to be a liquid infeed or supply conduit 12 possessing a curved portion 12a and which extends in the direction of travel of the material, as best seen from FIGURE 2.
  • the thus formed fiber layer is compacted under the action of an inlet guide or nozzle 14 so that the conduit mouth 13 disposed further below is completely encircled by fiber material, in order that this fiber material can then be handled by an externally support-, ing guide surface means which narrows towards the bottom, in this embodiment incorporating a spiral or helical wire 15.
  • the pitch of the spiral wire 15 i advantageously selected such that sufiicient intermediate space remains to permit the liquid streaming out of the discharge mouth 13 of the supply conduit 12 to be easily removed radially from internally of the spiral wire 15 through the fiber layer towards the outside, with simultaneous displacement of air.
  • the encasing or covering 16 disposed about the spiral wire 15 serves solely to protect the surrounding regions from spray.
  • the wire itself from which the spiral wire 15 is wound, is advantageously covered with a wearresistant, anti-adhesive jacket 17 providing small frictional resistance as possible, for example formed of Teflon or similar material (see FIGURE 3).
  • the formed sliver or band has passed through the spiral wire 15 and the liquid has moved from the inside to the outside thereof and the entrained air displaced, such is pressed by a pair of calender rollers 18 with high specific pressure, so that excess liquid escapes and is separated therefrom.
  • excess liquid as employed herein there is to be understood a quantity of liquid which is greater than that quantity which the fiber layer or material can retain, even under the most favorable conditions.
  • the calender rollers 18 preferably embody disks or plates 18a which correspond to the width of the sliver or band. Additionally, this pressure zone or region is laterally closed or bounded by a respective plate 19. It should be appreciated that such pressure zone builds up liquid pressure to obtain a hydrodynamic action which compacts, forms and smooths the band.
  • FIGURES to 7 Another embodiment of the present invention is de picted in FIGURES to 7.
  • the infeed conduit 20, as best shown in FIGURES 6 and 7, widens into a hood or cap 22 connected with a spiral wire 21 providing the guide surface means.
  • the guide surfaces of the spiral wire 21 itself transform from an initial oval cross-section into a tubular cross-section at the mouth thereof (see FIGURES 5 and 7).
  • the hood 22 extends approximately to the center of the shorter sides 21a of the spiral wire 21 as clearly shown in FIGURE 7, in order on the one hand to guarantee for the passage of liquid from the hood 20 into the longer side 2112 of the aforesaid spiral wire 21 and through the sliver or band and, on the other hand, again out of this spiral wire as a transverse throughfiow.
  • the inlet guide or nozzle 144 there is arranged the inlet guide or nozzle 144.
  • a small pair of calender rollers 23a embodying disks 23 (FIGURE 5) advantageously corresponding to the desired sliver or band width, the clamping line of which is located within the cover or boundary plates 24 disposed at both sides of said disks 23.
  • cover plates 24 together with the disks 23 form a pressure zone and free the sliver or band leaving the spiral wire 21 from surplus or excess liquid.
  • This removed excess liquid is collected in containers or vats 25 and from there is again delivered to the circulation system.
  • one of the calender rollers is mounted to be stationary and the other is displaceably mounted under spring pressure, as at 2312, for generating pressure.
  • the internal surfaces 26 of the multiple threads 27 which narrow towards the bottom undertake the function of the guide surface means.
  • the liquid introduced via the pipe or tube 28 thus flows, after radial passage through the fiber layer exhibiting ring-shaped cross-section, downwardly in the spiral-shaped constructed course of threads 29, where it discharges or escapes.
  • nozzle cascade 30 In the modification shown in FIGURES 9 and 11 the introduction of liquid occurs in a nozzle cascade, generally denoted by reference numeral 30.
  • This nozzle cascade 30 is advantageously formed by threading or other- Wise connecting circular plates 31 having nozzle-shaped bores 32 onto one another, and from which bores radial grooves or channels 33 are milled, or otherwise formed, which serve for the discharge of air and liquid escaping from the formed band or sliver.
  • the diameter of the respective bores 32 of the individual plates 31 reduces in size in the direction of material or band travel towards the discharge mouth.
  • FIGURE 10 A further possibility for introducing liquid into the fiber layer is depicted in FIGURE 10.
  • the fiber layer is directly conducted into the spiral wire 34 with the elimination of an inlet nozzle.
  • the spiral wire 34 is pronouncedly displaced above the discharge mouth of the liquid infeed conduit or delivery pipe 35, as shown, and forms from the outset a strongly narrowing guide surface means.
