Definitions

  • the invention relates to a method and an apparatus for structuring a nonwoven web by a needling process, in which the brush belt runs all the way around supported nonwoven web transported through a needling zone and is needled there.
  • Method and device of this Art are known for example from US 5 144 730.
  • the invention is therefore based on the object of a method of the type mentioned at the beginning, that with structurally simple Medium is executable and a high throughput speed the nonwoven web through the needling process enables.
  • the advantage of the invention is that at least in the area in who has a high density of needles on the needle board, the use of a hold-down device can be dispensed with.
  • the fleece is between the bristles of the brush belt needled fibers of the nonwoven web due to the friction between the bristles and these fibers on the brush belt like this noted that by the return movement of the needles Forces caused by the needles are not sufficient, to lift the nonwoven web off the brush belt.
  • the needle board Because of the waiver the occupancy density of the Even needles on the needle board compared to the usual size increase even further, because of the limits set by a hold-down device are no longer to be considered, and it becomes possible that The needle board also tracks the feed of the nonwoven web Have movement carried out without a hold-down device to be hindered, with which the needles would otherwise collide.
  • the nonwoven web In the entry area of a needle machine, where the adhesion between the fibers of the nonwoven web and the bristles of the brush belt is still not sufficient, the nonwoven web securely on the It is advisable to hold onto the brush belt from the waiver to provide a hold-down device, so that the needle density there Needle board must be correspondingly smaller. But as soon as one sufficient number of fibers from the nonwoven web into the Brush tape are needled, i.e. in subsequent needling zones, can dispense with the hold-down device and the occupancy density be enlarged with needles on the needle board.
  • Fig. 1 shows schematically one for carrying out the invention Process-installed system from its long side.
  • she comprises two needle machines 1 and 2, which are in the transport direction one unwound from a supply roll 3 and from a take-up roll 4 wound, schematically designated 5 Nonwoven web are arranged.
  • Rolls 3 and 4 are more common Way stored on support rollers 6.
  • the brush belt 7 consists of a plurality of adjacent Strips 10 with bristle tufts 11 anchored therein, the free ends of the bristles of the bristle tufts one form a continuous, flat surface to accommodate the Nonwoven web 5 is determined.
  • the strips 10 are in their foot area 12 each held interchangeably in support profiles 13.
  • the carrier profiles 13 are in the upper run of the brush belt 7 from supported below, which is not shown in Fig. 1, not sag and withstand the needling pressure.
  • the so far The construction described is conventional in this respect, see for example DE 40 22 237.
  • the needling machine 1 has two needling zones, each one Needle bar 14 or 14b is assigned.
  • the two needle bars 14a and 14b are firmly connected to one another by a cross frame 15, by two hinged to it and on eccentric 16 mounted connecting rods 17 in a vertically swinging movement can be moved.
  • the cross frame 15 a connecting rod extending substantially horizontally 18 articulated, which is mounted on a further eccentric 19.
  • By rotating the eccentric 19 can be by means of the connecting rod 18 the cross frame, and with it the two needle beams 14a and 14b, in a horizontally swinging motion.
  • phase-appropriate superimposition of the rotating movement of the eccentrics 16 and 19 can be achieved that the needle bars 14a and 14b in the side view of FIG. 1 a clockwise Perform movement depending on the eccentricity of the eccentric 16 and 19 is circular or elliptical. In this respect, too Design and operation shown in Fig. 1 known.
  • first needle board 20a On the underside of the needle bar 14a is a first needle board 20a attached while on the underside of the second needle beam 14b a second needle board 20b is attached. Both needle boards 20a and 20b have a plurality of needles 21 occupied, however the occupation density is at the first needle board 20a less than the needle board 20b. Also located between the first needle board 20a and the brush belt 7 Hold-down 22, while one below the second Needle board 20b is missing. The hold-down 22 is with slots provided for the passage of the needles 21.
  • the needles 21 in the state in which they are in the fiber fleece web 5 supported on the brush belt 7 are produced by the drive devices 9 Track movement of the brush belt 7 while in the out the fiber fleece web 5 lifted out again in its starting position before the new puncture into the nonwoven web 5 to return. This tracking the feed movement of the nonwoven web reduced by the needles in a known manner Distortion on the nonwoven web and reduces damage this and on the needles.
  • the nonwoven web with moving at a speed through the facility that very much is greater than the speed to be observed if the needle bars only perpendicular to the nonwoven web would be moved.
  • the dwell time of a length segment the nonwoven web in a needling zone due to the increased Transport speed is relatively low, results in constant stitch frequency a comparatively low Needle puncture density in the fleece. To compensate for this, the population density with needles on the needle board must be increased become.
  • the fibers gripped by the needles 21 from the Nonwoven fibrous web 5 pressed so deep into the brush belt 7 be that the frictional forces between the bristles of the Bristle tufts 11 and the fibers from the nonwoven web 5 developed be, the nonwoven web 5 on the brush belt 7 so It is important to note that a hold-down device is not used can be. This is the second needle bar 14b shown.
  • a first needling zone is provided, which the first needle bar 14a belongs to, the one needle board 20a carries, which is sparsely populated with needles 21 is, so that the use of a hold-down 22 is possible.
  • a free-running pressure roller 23 downstream of the second needling zone provided.
  • Such a pressure roller 23 could also be between the first needling zone and the second Needling zone may be arranged when the hold-down 22 on the outlet side shouldn't be long enough.
  • the needle bar here only is shown schematically, but there on any hold-down is dispensed with, because the nonwoven web is already sufficient is firmly anchored to the brush belt to prevent fluttering prevent.
