Definitions

  • the invention relates to a method for producing velor needle felt webs by processing, d. H. Needles, a nonwoven fabric by means of felting needles for the purpose of solidifying the same and subsequent needling of the pre-consolidated nonwoven fabric by means of fork needles forming fiber pile loops.
  • a machine or system for producing such velor needle felt webs consists of the carding machine, the cross or cross layer, a pre-needle machine, a main needle machine, a velor needle machine and the necessary facilities for post-treatment of the mechanically processed material web.
  • the invention has for its object to propose a method by means of which a high quality velor needle felt material can be produced, which is in no way inferior to the velor materials produced by other methods and compared to the previously known velor needle felt material a much more favorable fiber distribution in terms of Has pole and bottom material and which is considerably less complex to implement.
  • a high quality velor needle felt material can be produced, which is in no way inferior to the velor materials produced by other methods and compared to the previously known velor needle felt material a much more favorable fiber distribution in terms of Has pole and bottom material and which is considerably less complex to implement.
  • Such a web material is the same as all other velor material webs and can compete with them in terms of the quality of the product.
  • Another object of the invention is to propose a machine suitable for carrying out the method according to the invention.
  • velor needle felt webs in such a way that at least at least one nonwoven web consisting of several layers is helically wound into a tube rotating about its axis and continuously moving in the axial direction, the individual layers of the nonwoven tape partially overlapping each other so that the wound tube is then smaller than the width along a tube section adjoining the inlet edge of the nonwoven tape, as seen in the tube pull-off direction, which is smaller, preferably up to about half smaller of the nonwoven tape, is solidified in a manner known per se by means of felting needles and that then from the upper or outside loose fiber layer of the wound tube, the fibers forming the pile loops are also pressed in a known manner by means of fork needles through the pre-consolidated lower or inner fiber layer.
  • the individual layers of a nonwoven fabric tape are offset from one another and placed on top of one another in the direction in which the tube is drawn off.
  • the individual layers are placed at an acute angle to one another at an acute angle with respect to the cylindrical bearing surface of the hose.
  • the above-mentioned lateral offset of the layers when the nonwoven tape is built up must be so large that the inclined edge surface of the nonwoven tape is substantially parallel to the support surface when the tube is formed or adjoins the oblique edge surface of the previous turn.
  • the method proposed according to the invention offers the essential advantage that the fiber material wound into a tube is only solidified with respect to a certain height in order to form the soil and that the loose fiber material located above this pre-consolidated and sufficiently dense fiber layer is largely pushed through the pre-consolidated fiber layer to form the pile becomes.
  • the area in which the fleece wound into a tube is processed can be relatively small, since due to the rotation of the tube with simultaneous axial movement, the fiber material is adequately processed, which in turn requires relatively little equipment and a much lighter construction the machine requires.
  • the machine for carrying out the method according to the invention has a shaft which is arranged in a stationary manner on a frame and which is provided with a lamellar web wound onto it with a uniform pitch and fastened thereon, which is opposite to it with at least one radially movable to the shaft, with felt and Fork needles equipped needle bar is arranged.
  • a nonwoven tape feed device and at least one hose rotating and feeding device consisting of an endless conveyor belt are assigned to the shaft designed in the aforementioned manner.
  • the endless conveyor belt is guided over at least two deflecting rollers, a strand of which rests under tension on the outside of the hose, so that the hose is entrained and rotated due to friction when the conveyor belt moves.
  • two needle bars are assigned to the shaft covered with a lamella web, so that two nonwoven webs can also be fed to form the tube, which can increase the performance of the machine.
  • a tubular shaft 12 is fastened horizontally to a frame of the machine 11 (not shown in detail), on the outer surface of which is spiraled out with a slope that corresponds to the distance between the needles in the needle bar a steel strip existing slat web 13 is wound and fastened.
  • the upper and lower needle stations 14a and 14b are arranged in the longitudinal direction of the shaft, which in principle have the same structure, which is therefore only described in more detail below with reference to the upper needle station 14a.
  • the needle bar 15 which extends over a certain length of the shaft 12, carries two groups of needles one behind the other in the longitudinal direction of the shaft, namely the felting needles 16 and behind them the velor or fork needles 17.
  • the needles 16 and 17 are passed through openings in the hold-down plate 18, between which and the nonwoven web 19 is fed to the outer edges of the lamella webs 13.
  • the needle bar 15 is carried by one or more rockers 20 which are mounted on an axis 21.
  • the needle bar 15 is set in a swinging up and down motion, the needles with their free ends of the layered fleece built up over the lamellae 13 of the shaft 12 25 penetrate in a manner known per se and on the one hand solidify the area of the fiber fleece 25 adjacent to the lamella 13 or on the other hand through the fibers from the outer, loose layer of the fleece to form the pile loops push through the solidified base layer.
  • the nonwoven web 19 is fed to the needle stations 14 via the guide plate 26.
  • the feed speed of the nonwoven web 19 is synchronous with the speed of rotation of the fiber material tube 27 formed around the shaft 12 with its fins 13, which tube is rotated constantly uniformly with the aid of the tube turning device.
  • This consists of the two endless conveyor belts 28, 29, which are deflected via the two upper rollers 30, 31 and the lower rollers 32, 33 and tensioned by means of rollers 34 and 35 and bear against the fiber material tube 27 under appropriate pretension and against them press on the lamella webs 13 and take them with them as a result of the friction effect according to their own movement, the direction of which is marked by arrows.
  • the lamellae 13 consist of a spirally wound web and in the second part of the needle station 14 the pole loops are pressed into the space between two adjacent lamellae, when the fiber material hose 27 is rotated, it is automatically moved axially with a corresponding rotation corresponding to the gradient of the lamella web 13.
  • the previously described machine 11 is assigned a carding machine 41 with a pile divider 42 which divides the card web 43 emitted by the carding machine into card webs 44a to 44e.
  • the card web laying device 45 deflects the card webs 44a to 44e in the manner shown and the individual card webs 44a to 44e towards one another in such a way that the band lying above the bottom card web lies offset with respect to the bottom card web so that the nonwoven web 46 formed in this way extends there are five mutually offset layers which have a tapered edge region 47 or 48 on both sides, as can be seen from FIG. 3.
  • the pile belts 44a to 44e or the nonwoven web 46 formed from them are deposited on the conveyor belt 49, which feeds them to the nonwoven web feed and guiding device 51, which ensures that the nonwoven web 46 is stacked in the manner to form the fiber material hose 27 that the individual layers of the nonwoven web 46 are inclined at an acute angle and an evenly high fiber material layer with a uniform, homogeneous fiber distribution is obtained, as can be seen in particular from FIG. 3, which schematically shows the structure or the layering of the fiber material tube 27.
  • This type of formation or layering of the fiber material to be needled and by the arrangement of the needling zone in the area of the entry of the nonwoven web 46 into the machine 11 ensures that the needles of the needle group 16 serving to pre-consolidate the base layer 61 only the lower or inner one Detect layer 61, but not the fibers lying in the upper or outer loose layer 62, which are detected by the velor or fork needles of the needle groups 17 when the fleece band 46 runs in and the hose 27 continues to move, and by the lower or inner layer 61 to form the pole loops and be pushed into the spaces between the individual lamellae 13.
  • FIG. 3 is only schematic insofar as in the area of the needling zone and behind it the nonwoven material of the tube 27 effectively takes on a different shape, i. H. that the surface sinks and the material thickness becomes smaller because on the one hand it solidifies and on the other hand the fibers have been pressed through the solidified layer as pile loops.
  • Fig. 3 the theoretical structure of the fiber material from which the fiber material tube 27 is formed is primarily to be shown.
  • the fiber material tube 27 formed in the manner described is, as can be seen from FIG. 4, either immediately after its formation or after further treatment of its outside, for example by applying a coating, cut open in a manner known per se by means of a cutting device 71 which is rotatably mounted and is rotated synchronously with the hose in order to obtain mutually parallel edges 71, 72 of the flat-lying velor needle felt web 73.
  • the web 73 is finally wound up into a bale 76 with the aid of the winding device 75 which can be rotated about the hose axis 74.
