Definitions

  • the invention relates to an apparatus and a method for Production of a fleece from fibers.
  • Such fleeces are used in particular for the production of molded parts, Insulating mats and upholstery material.
  • Cards / cards are able to be particularly fine and even Manufacture nonwovens, but they also place the highest demands the absence of shives and the degree of opening of the fibers. Your Production performance is very low with a maximum of 500 kg / h, the cost are correspondingly high.

  • Aerodynamic fleece molding plants place less demands on the freedom from shaving and the degree of opening of fibers.
  • the output reaches about 1,000 kg / h. But that is still not enough to reduce the costs for mass products to reach.
  • Fibers that meet these requirements of the known systems can only be produced from roasted hemp or flax straw. But roasting is a biological one Degradation process and therefore inevitably pulls a weakening of the fibers after itself. For technical purposes, fibers are of maximum strength and maximum E-module required.
  • the object of the present invention is, therefore, for nonwovens Insulation purposes, upholstery materials, etc. to manufacture, which is characterized by Mark up minimal costs. In particular, it should also such nonwovens are economically manufactured, from which molded parts with a high modulus of elasticity and high strength.
  • nonwovens can now be produced in which the two production stages mentioned, namely "shaving separation” and “fiber opening” are no longer needed because of the process and with the corresponding device according to the invention in extreme cases Uncleaned and unopened fibers can also be processed can.

  • liquid binders and additives are therefore only first after the long fiber material has left the discharge head A via the introduced first nozzles 40 so that a connection or Addition of such components to the long fiber elements and these, if necessary, previously added mixture components occurs immediately during the formation of the fleece, i.e. the liquid Binders, additives or foams are passed through the first nozzles 40 into the loose long fiber air suspension according to the desired one Quantity ratio sprayed or dropped.
  • This system can also be used for Introduction of solid additives such as additional ones Shives, granules or powdered binders, for this are Solids distributor 50 provided in the illustrated embodiment alternating with the first nozzles 40 above the Suspension space S are arranged.
  • First nozzles 40 and solids distributor 50 thus form one "Curtain" of the desired liquid or solid additives into the fleece 70 forming on the forming belt 14 in such a way that a largely homogeneous structure of the fleece 70 from the base materials, the long fibers, and the additional components , be it that these are already in a suitable form together with the long fibers are applied to the transverse distributor 11, be it that these are expediently or necessarily from the nozzles 40 or the solids distributors 50 if they are Conveying the material column M through the discharge head A unreasonable would complicate.

This requires large heights of the device according to the invention for the metering bunker 10 in order to achieve large throughputs.
  • the compressor belt 13 can first be used, and the bulk density can be increased over its length and angle of inclination to a multiple of the specified initial value, so far until a satisfactory work of the discharge head is still guaranteed with the long fiber composite currently available.
