Definitions

  • a fibrous web taken from a carding machine hereafter referred to as "batt”
  • a crosslapper on a transversely to the feed direction of the fibrous web endlessly circulating support a multilayer nonwoven web, hereafter referred to as nonwoven fabric produced, which fed to a needle machine and there is solidified by needling.
  • the stretching of the card web generates in this a reorientation of fibers, with the result that has the orientation of the fibers within the cross-laid nonwoven web transversely varies to the web direction, which in turn the stretch properties of the nonwoven web influenced by needling produced product.
  • There are places in the finished product have track characteristics different from those of other places. In general, however, finished products are desired whose stretch characteristics the largely regardless of the stretch direction.
  • the invention has for its object to provide a device and a method, with which a transversely profiled nonwoven web can be produced, the no Has fiber orientation disorders.
  • the batt is formed by means of an aerodynamic pile generator.
  • Aerodynamic pile generators are already known, for example, from DE 101 44 728 A1.
  • the pile producer has facilities with the help of the Florabgabe in operation is changeable.
  • the aerodynamic pile generator lays a batt that does not orientate has, so a random fiber pile, on an air-permeable surface from.
  • DE 101 44 728 A1 is said to be, whose conveying speed can be regulated by means of a control unit become.
  • the invention While aerofoil-making is commonly used to produce high basis weight webs of up to 400 g / m 2 which, because of this high basis weight, can be directly subjected to needling, water jet or thermobonding consolidation, the invention combines mechanical aerodynamic web production Web formation by crosslapping, for which purpose preferably thin webs with a basis weight of up to 20 g / m 2 down aerodynamically generated.
  • the random fiber pile is thus laid in a cross-lapper to a nonwoven web.
  • the special feature of the invention is that by appropriate control of Ab grind whatsoever the pad on which the pile is stored in the aerodynamic Florerzeugung, in the formed goal web thick and thin areas can be generated at regular intervals, these distances from the Spreading width depends on crosslapping. By suitable adjustment of the cross-stacking movement, it is then possible in a known manner to ensure that the thin places of the card web are deposited in the edge regions of the nonwoven web produced, so that the desired thickness profile of the nonwoven web is seen in the transverse direction.
  • the cyclical change required for the particular application as described the basis weight of the aerodynamically generated card web is made by changing the speed of the air-permeable pad, preferably an endlessly circulating Sieve belt, which receives the fibers fed to it and the formed thereon card web transported away in the direction of the stacker.
  • the speed of the air-permeable pad preferably an endlessly circulating Sieve belt
  • the speed with which the screen belt rotates arises on the screen belt Florbahn whose basis weight inversely to the transport speed of the wire belt fluctuates. Due to the cyclic change in the transport speed of the screen belt
  • a card web is produced, which has thin points, the regular distances from each other and which is suitable for the production of a profiled nonwoven web.
  • the Unoriented fiber layer is in both the thick and in the thin areas of the card web available.
  • the aerodynamic pile generator can be fed directly from a feeder because it is due to its design to some extent also performs the function of a roller card and in some cases the quality requirements waiving the use of a separate one Allow clutter.
  • a feeder which has already been mentioned that Nonuniformities in the batt due to the effect of the crosslapper to some extent be compensated.
  • special quality is important, is the aerodynamic Florerzeuger preferably supplied by a roll card with fibers. Of the Florerzeuger then delivers despite the longitudinal orientation of the fibers in the of the carding given and supplied to him cardstock a Wirrmaschineflor, because he the card pile completely dissolved in single fibers, which then aerodynamically without preferential direction on the air-permeable base are stored.
  • the core assembly K in the present invention of FIG. 1, a tangled fiber file producer, comprises a Ganzstahlgarniturwalze 1, the several provided with trims Abdeckmulden 2 face each other.
  • the all-steel set roller 1 rotates at high speed, according to Fig. 1 in a clockwise direction.
  • the cover troughs 2 are intended to rotate during rotation the all-steel garnish roll 1 to keep the fibers on this.
  • the all-steel set roller 1 is on the inlet side a pair of feed rollers 3 and 4 opposite, which also with all-steel sets are provided and between them or together with the Ganzstahlgarniturwalze 1 each form a gap at the supplied fibers of the one Roller to be handed to the other.
  • the upstream of the feed rollers which in 1 is provided with the reference numeral 4, is a Flor Insertsmulde 5 opposite, the one with the circumference of the feed roller 4 in the direction of rotation of the feed roller. 4 forming narrowing gap.
  • the drain side Guide roller 6 of an endlessly circulating conveyor belt 7 is arranged, which for feeding of fiber material from a feeder (not shown in Fig. 1).
  • the Ganzstahlgarniturwalze 1 is in a range in the direction of rotation of this roller. 1 located between the wells 2 and the feed roller 3, a scraper 8 opposite, below which there is an endlessly circulating sieve belt 9, which has several Deflection rollers 10 and 11 is guided. Under the upper run of the sieve belt 9, the Scraper 8 faces, there is an open-topped suction box 12 which is connected to a Vacuum source (not shown) is connected. Furthermore, a baffle 13 is to be mentioned, which is located in a sector between the wells 2 and the scraper 8 and delimiting a fiber flight channel extending from the all-steel clothing roll 1 toward extends to the portion of the upper run of the screen belt 9, which extends above the suction box 12 is located. In a space below the baffle 13 and above the Siebbandes 9 is a pressure roller 14, which with the screen belt 9 a gap formed.
  • the guide rollers. 6 and 10 characterized as having an individual drive means. These drive devices are connected to a control unit 15, which is shown in the drawing is indicated by corresponding connecting lines.
  • one of a feeder (not shown) or a Carding (also not shown) dispensed and introduced via the feed belt 7 Fiber material in the narrowing gap between the first feed roller. 4 and the trough 5 introduced. Due to the all-steel set of feed roller 4 is the supplied fiber mass evened. It is from the first feed roller 4 of the adjacent and in the opposite direction of rotation rotating second feed roller. 3 pass and thereby evened out. From the second feed roller 3 are pass the fibers of the Ganzstahlgarniturwalze 1, which further uniformizes the pulp and isolated and the fibers with the help of the Abireers 8 aerodynamically deposits on the screen belt 9.
  • the upper run of the screen belt 9 is by means of in the Suction box 12 prevailing negative pressure under suction, what the fiber deposit on the wire belt 9 favors and helps avoid flyaway.
  • the fiber deposit on the screen belt 9 takes place completely undirected, i. the fibers within the formed on the wire belt 9 Flors have no preference orientation.
  • the pile formed on the screen belt 9 is from Sieve belt, which revolves endlessly, transported away as a coherent card web.
  • Fig. 2 shows the application of this core unit K of FIG. 1 in an inventive Apparatus for producing a fibrous web.
  • the aforementioned core unit K is located between a feeder 16 and a stacker 17, which on the screen belt 9 produced fiber web is fed.
  • the stacker is designed here as a pier arm and will not be explained in detail.
  • the devisrm the steep arm 17 leads above a take-off belt 18 a reciprocating motion. In the area of reversals of the laying arm of the steep arm 17, the speed of the Florabgabe must the discharge belt 18 reduced because of the necessary deceleration of devisrms to avoid unevenness of the pile storage. The transfer of fibrous web From the screen belt 9 to the steep arm 17 must therefore be adjusted accordingly.
  • FIG. 3 shows a device comparable to that shown in FIG. 2, which is provided with a temporary store Z is supplemented.
  • the buffer Z consists of an endlessly circulating second screen belt 19 and a storage roller 20, which is between the first wire 9 and the second screen belt 19 is arranged and stored on the first screen belt 9 card web decreases from there and deflects to the underside of the second screen belt 19, to which the Florbahn is sucked by a negative pressure, which in a between the two runs the second sieve belt 9 arranged suction box 21 prevails.
  • the storage cylinder 20 is along the two sieve belts 9 and 19 movable and thus able to the length the located between the core unit K and the stacker 17 Florbahnabitess to change. An enlargement of this length causes a pile absorption, i. an intermediate storage, a reduction a corresponding Florabgabe from the Cache Z.
  • the first screen belt 9 can, from the needs of a profile formation if necessary apart, be driven independently of the stacker 17.
  • the embodiment of FIG. 4 differs from the embodiment of FIG. 2 in that between the feeder 16 and the core unit K a roll card W with two customers and a buffer Z are arranged.
  • the roll card W has an upper pickup 22 and a lower pickup 23.
  • the lower pickup 23 lays the fibrous web removed from the carding drum 24 of the roll carding W on endless circulating pile conveyor belt 25.
  • the upper loader 22 also places one Fibrous on an endless circulating transfer belt 26, the latter Flor on the Flortransportband already located on the pile 25 sets, of the lower Customer 23 comes. If a higher flange thickness is desired, can on the Krempeitambour 24 also more than two customers, for example, four customers, be present.
  • the invention is not limited thereto.
  • the pile conveyor belt 25 is at the same time part of a buffer Z, to which a pile storage roller 20 heard between the Flortransportband 25 and the cache Z is arranged and along the Flortransportbandes 25 and the cache Z is movable.
  • This storage roller 20 operates in the same manner as described with reference to Fig. 3 has been explained.
  • a fiber mass fed from the reservoir 16 is separated from the roll card transformed into a uniform pile, in two layers of the upper and lower Pickups 22 and 23 removed and placed on the pile conveyor belt 25.
  • the double-ply card web is fed via the temporary storage Z to the core unit K, where they in the same manner as described with reference to FIG. 1, in individual fibers is dissolved, which are stored on the screen belt 9. It can by appropriate Control the running speed of the screen belt 9 to ensure that Thick areas and thin areas are produced in the produced random fiber web.
  • the fiber feed must be in the core unit K in vote be controlled with the Flor supply the Buchlegers 17. That means the feed in the core unit K must be varied in time.
  • the roll card W the two card webs, which are superimposed on the pile conveyor belt 25, with constant speed and thickness. The difference between this constant Florabgabe of the roll card W and the pile recording at the core unit K is compensated by the buffer Z.
  • FIGS. 2 to 4 refer to the representation of the control devices has been dispensed with for driving the various units. It should be noted that a speed modulation at the carding drum 24 and at the all-steel set roller 1 because of the large masses excreted, leaving alone the drives of feed rollers, storage roller and second screen belt 19 of the pile store into consideration come.
