Definitions

  • the invention relates to a needle board for a needle machine, in which a plurality of needles in a predetermined pattern in the region of the base plate is arranged and the tips of which protrude from the base plate.
  • Needle machines are well known and, for example, in Lünenschand and Albrecht: “” Nonwovens “, Georg-Thieme-Verlag Stuttgart, 1982, pp. 122 to 129 described.
  • the needle boards used in such a needle machine usually consist of a base plate made of aluminum, from whose holes the needles protrude, and attached to its back, appropriately drilled plastic plate, in particular of a polyamide (nylon), in the back grooves are milled into the the holes open.
  • the grooves serve to receive the bent at the rear ends of the needles portions of the needle shafts.
  • the holes in such a needle board are closely matched to the shaft diameter of the needles held by the needle board so that the needles in the needle board are as tight as possible and do not wobble in use.
  • the needle board rests on the back of the needle bar of the needle machine to which it is attached, whereby the bent portions of the needles are held in the grooves.
  • a needle board which has a plurality of needle modules equipped with needles.
  • Each needle module comprises eight needles and is fixed by means of screws on webs of the needle board.
  • the present invention is therefore an object of the invention to provide a needle board for a needle machine that can be easily manufactured, a long life has, and in the replacement of defective needles or a replacement of the needle board can be made in a simple manner.
  • the needle board for a needle machine on a base plate and a plurality of needles which are arranged in a predetermined pattern in the region of the base plate and the tips of which protrude from the base plate.
  • the needle board on a plurality of needle modules each of which has a support plate which is equipped with a plurality of needles, inserted into a receptacle of the base plate and held there to prevent movement of the support plate form-fitting or frictionally engaged.
  • the receptacles are formed as slots in the base plate.
  • the slot formation can be done by a simple machining operation, so that the production of the needle board is further simplified.
  • the carrier plates may preferably have a protruding edge portion, which rests in each case on a shoulder in the wall region of the corresponding receptacle in the base plate.
  • the protruding edge portion and the paragraph are formed circumferentially.
  • the carrier plates are preferably formed from plastic.
  • a particularly simple form of production is achieved when the carrier plates are cast or sprayed onto the needles.
  • the needles can be inserted into recesses of the prefabricated carrier plates.
  • the needles may preferably have upset or angled heads.
  • the shafts of the needles can also be roughened.
  • FIG. 1 the schematic structure of a needle machine is shown.
  • a fleece 2 is supplied at the inlet of the needle machine and conveyed to the needle zone.
  • a needle bar 4 with a needle board 6 attached thereto is arranged, which is equipped with needles 8 for solidifying the nonwoven.
  • the nonwoven 2 to be needled is guided between a hold-down plate 10 and a throat plate 12.
  • the needles 8 densify the web 2 by being pierced into the nonwoven web at a high frequency and pulled out again. They pass through recesses in the hold-down plate 10 and the needle plate 12 therethrough.
  • the resulting product is a consolidated web 14.
  • the person skilled in the various forms of needle machines are known, including double needle machines, which is needled from above and below by means of two needle bars, or needle machines in which the needle bar during the solidification process in the direction of movement of the web be moved.
  • the needle board 6 according to the invention can be used for any type of needle machine.
  • Fig. 2 to 4 a first preferred embodiment of the needle board 6 according to the invention is shown.
  • the needle board 6 comprises a base plate 16, in which a plurality of receptacles 18 is formed, which are formed here in the form of longitudinal slots.
  • the base plate 16 is preferably made of aluminum, but other materials such as magnesium, etc. are also possible.
  • In the slots 18 each needle modules 20 are inserted.
  • Each needle module 20 has a carrier plate 22, which has a plurality of recesses 23, in each of which a needle 8 is inserted.
  • Fig. 2 three needle modules 20 are shown on the one hand in a state separated from the needle board 6 and on the other hand in a state introduced into the needle board 6. To better illustrate three slots 18 of the needle board 6 are shown unfilled in the right part of the figure.
  • each slot 18 may have in its wall portion a peripheral shoulder 24 on which in the inserted state of the support plate 22, a protruding edge portion 26 of the support plate 22 rests.
  • the shoulder 24 and the protruding edge portion 26 may also be omitted.
  • the necessary force for holding the needle modules 20 in the base plate 16 is generated by frictional engagement.
  • a conical narrowing of the slots 18 in the direction of its lower edge and a corresponding shape of the support plates 22 is conceivable.
  • the needles 8 themselves can have angled heads (not shown) which, for example, lie in a correspondingly shaped groove of the carrier plate 22 and terminate flush with the outside of the carrier plate 22.
  • the needles 8 can only be held by the clamping forces of the fit between the shaft of the needles and the carrier plate 22. Likewise, you could also upset the head of each needle 8, so that a positive connection is created.
  • the needle shaft can be roughened in each case.
  • the loading of the needle modules 20 with the needles 8 can be done conventionally by impressions, or the needles can be provided in a predetermined pattern, then to the carrier plate 22 or to inject.
  • placement machines can be provided which perform these standardized operations without manual effort. Likewise, it is conceivable to run both processes in a machine.
  • the alternative casting or injection molding of the support plate 22 made of plastic to the needles 8 can preferably be done automatically.
  • each needle module 20 includes a row of needles 8.
  • any other geometric arrangement of the needles within a needle module 20, and the arrangement of the different needle modules 20 to each other can also vary arbitrarily.
  • the needles 8 are arranged in rows in the direction of movement of the web.
  • Other orientations show the in Fig. 5 to 7 illustrated embodiments.
  • the needles 8 are arranged in rows transversely to the direction of movement of the fleece, in Fig. 6 at an angle.
  • Fig. 7 shows no arrangement of the individual needle modules 20 in groups, but a staggered arrangement of the individual needle modules 20 in a pattern.
  • the slots 18 may also have other orientations, and any other shape of receptacles 18 may be formed in the base plate 16.
  • the material of the support plate 22 is preferably a hard plastic that may be reinforced with glass fiber.
  • the support plates 22 may be flat for installation in flat needle boards 6, or they may be formed curved for installation in curved needle boards 6. However, it is also possible to use planar support plates 22 in curved needle boards 6, since in the attachment of the needle board 6 on the needle bar 4, the needle board 6 straightened.
  • the user is enabled to load or change needles 8 in the needle board 6 very quickly.
