Definitions

  • the invention relates to a needle for the mechanical solidification of Fibrous fleece by needling, consisting of a shaft with a tip on one, front End and a mounting piston at the other, rear end and several at the Shank-shaped barbs for gripping fibers from the needles Non-woven fabric, some of the barbs opposing that of the needle tip specified stitch direction and the other barbs in the from the needle tip specified direction of stitch.
  • a needle of this type is in AT 405 417 B. described.
  • the aforementioned publication describes a device for needling a Pre-consolidated fleece with a back and forth drivable in the puncture direction Needle board, which is filled with a variety of needles, and one of the needle board opposite underlay. This is explained in the discussion on the prior art Documentation that not only the needles ensure a good matting of the fleece when puncturing, but also when pulling fibers out of the fleece Take the fleece surface with you. For this purpose, it had already been proposed Use needles that are aligned both in the insertion direction and in the extraction direction Have barbs for fiber entrainment.
  • 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. Needles with a round shaft cross section are also known.
  • DE 195 21 796 C1 describes one in particular for needling a nonwoven fabric onto a carrier fabric certain felting needle with a cylindrical needle piston which is in a in a needle tip outgoing needle shaft with a polygonal cross section merges into its area at least one barb is formed, which does not have the outer surface of the Needle shaft protrudes to avoid damage to the carrier tissue.
  • the barb depth adapted to the shaft thickness is for the fiber 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.
  • Forward and backward barbs can be 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 consequence that when the Needle into a non-woven fabric, the notch following a preceding 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.
  • Needle types with three, four or six edges are preferred.
  • a needle with one Square cross-section would have preferred on two opposite edges, i.e. by 180 ° offset, one forward notch each, the other two notches each a reverse notch, each arranged at the same distance from the needle tip.
  • Needles with hexagon or star-shaped cross-section are not yet known.
  • the stitch section of a needle with a square shaft 1 and tip 2 can be seen in FIG. 1 the shaft 1 is near the tip 2 on each shaft edge 3a a forward notch 4th formed, while on the adjacent shaft edge 3b a rear notch 5th is formed, the notches 4 and 5 are approximately the same distance from the tip 2.
  • the Notches 4 and 5 are bounded by forward and backward barbs 6 and 7, respectively.
  • 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.
