Definitions

  • the invention relates to a device for producing a spunbonded nonwoven made of synthetic filaments according to the preamble of claim 1.

  • additional connections are provided in the process shaft to initiate or remove auxiliary air flows as required in the process shaft.
  • such auxiliary air streams basically have the disadvantage that only an air-fiber flow optimized in front of the deposit can be produced. The air-fiber flows generated for cooling the filaments and for stretching the filaments remain unaffected.
  • This object is achieved in that between a filament outlet of the cooling shaft and a filament inlet of the process shaft, a short free path is formed, in which the cooling air is dissipated in an environment.
  • the invention was also not suggested that from WO 2000/065133 an apparatus for producing a spun nonwoven is known in which the stretching device is arranged at a distance below a cooling device.
  • the drawing device has a draw-off nozzle which is operated with a compressed-air flow in order, on the one hand, to generate a suction effect on the inlet side and, on the other hand, to generate an intensive air-fiber flow for drawing off the filaments.
  • a leadership of the filaments with relatively low air flow and low pressure conditions within a shaft system is not possible with the known device.
  • the invention has the particular advantage that the cooling air and the process air can be set independently of each other to the respective filament type.

  • It is essential that the cooling air within the cooling Chute is guided as possible in the direction of the filaments, so that a supporting conveying effect in addition to the cooling begins.
  • the filament curtain can be safely introduced into the process shaft, in which the injected process air generates a necessary for the hiding of the filaments Liehe pulling force on the filaments.
  • the process air is supplied separately to the process shaft.
  • the relatively low air velocity within the process shaft also favors the deposition of the fibers, wherein the diffuser of the laying device leads to a widening of the filament curtain and corresponding distribution of the filaments for spunbonding.

  • the filaments on both sides of the spinning device can be uniformly cooled by a cooling air flow.
  • the drawing of the filaments can likewise be carried out particularly uniformly in that an inlet region of the process shaft with air-permeable shaft walls extends between two opposite air ducts through which the process air can be injected in the process shaft.
  • the filament curtain can be uniformly stretched within the process shaft.
  • the air flow of the process air during injection into the process shaft can be advantageously further improved by having the process shaft for connecting the air ducts opposite air inlet openings with a plurality of air guide elements.
