Definitions

  • a felting needle consists of the clamping shank with a Attachment portion, which is usually a crutch angled from the shaft, optional a tapered intermediate shaft, a triangular shaft that carries barbs, and the top. Round-shank cross-section needles are also known.
  • the barb depth adapted to the shaft thickness is for the fiber absorption capacity of significant meaning. Another factor that determines fiber absorption is that Fineness of the fiber to be needled. Grasp needles with a large barb depth and transport more fibers than those with a small barb depth. The influence of Shank shape, barb depth and other parameters on the work result is in "Nonwovens" by Lünenschand and Albrecht, Georg Thieme Verlag Stuttgart, 1982, pages 129 to 142, described in detail.
  • the invention has for its object a needle of the type mentioned specify with the novel nonwoven bonding techniques with warp-like The fibers can be entwined without the needle rotating around its axis must be rotated.
  • the invention provides a needle in which on the working part, i.e. on the Shank, forward and backward oriented barbed notches for use come.
  • the needle cross-section can be round, single-edged / round, double-edged, triangular, square, hexagonal or star-shaped, so in the broadest sense it can be anything.
  • the forward and backward can be on one edge oriented notches one above the other, preferably arranged on one or more edges so that the forward notch, that of the one directed in the stitch direction Barbed notch seen from the needle point of the working part behind the Backward notch comes from that directed towards the crutch of the needle Barb is limited.
  • These forward and backward notches are preferably very much in close succession, and between them extends an elevation, preferably up to to an imaginary line that connects the opposing barbs.
  • Forward and backward barbs can be seen in a radial plane of the shaft
  • the circumferential direction can be arranged alternately.
  • the notches can be seen in different circumferential directions of the needle shaft Distances to the needle tip must be arranged, which has the result that when the Needle into a nonwoven fabric, the notch that follows a previous notch Encountered fiber state, which already changed by the effect of the previous notch has been. This can be advantageous if the fiber composite is still very loose and a simultaneous effect of all notches would cause undesirable disturbances.
  • the needle has multiple edges, they are on one edge Forward and backward notches are stacked on top of each other while on the adjacent one Edge backward and forward notches are arranged one above the other. Possibly. can also several pairs of notches can be arranged one above the other.
  • Needle types with three, four or six edges are preferred.
  • a triangular cross-section needle would prefer to have the following notches: on all three edges from the tip starting with a backward notch at the same distance from each edge Needle point. Above it at a short distance forward notches, one per edge in same height. The distance of the notches from the tip should be as small as possible usually about 3.2 mm. The short distance between the backward notches and the Forward notches would normally be a few tenths of a millimeter to a few millimeters.
  • a needle with a square cross-section would have preferred two opposite ones Edges, i.e. offset by 180 °, one forward notch each, the other two notches one each Reverse notch, each at the same distance from the needle tip.
  • needles with a hexagonal or star-shaped cross section are not yet known. Also in this regard it is provided according to the invention, alternating between forward and per edge and backward notch equidistant from the needle tip, i.e. in the same Alternate radial plane with respect to the needle shaft.
  • FIG. 1 shows the stitch section of a needle with a triangular shaft 1 and a tip 2.
  • An the shaft 1 is near the tip 2 on each edge 3 of the shaft 1 one Backward notch 4 and a forward notch 5 formed from forward and backward, respectively directed barbs 6 and 7 are limited. In that of the two barbs 6 and 7 limited space rises 8, the apex up to one imaginary connecting line between the ends of the two barbs 6 and 7 is sufficient.
  • the First a tuft of fibers is gripped by the forward notches and opened from the puncture side bumped the other side of the nonwoven.
  • the Backward notches tufts of fibers from the other side of the fleece in the same puncture hole withdrawn.
  • the fiber transports are different Stitch directions are independent of each other, and are also here in both stitch directions the fibers are pulled through one and the same stitch hole.
