Definitions

  • the invention relates to a device and method for solidifying a fiber composite with the features of the generic term of the independent claims.
  • Such a fiber composite is often referred to as a nonwoven.
  • the fiber composite consists of a mixture of basic fibers, for example cotton fibers or flax fibers and from Binding fibers, for example meltable plastic fibers. binder fibers can be melted by heating. Thereby the loose fiber composite can be consolidated. To solidify It is known from such fiber composites that the fiber composite is continuous along a conveyor path in a dryer device to promote and thereby apply heat. Subsequently the fiber composite is cooled.
  • Non-woven mat can be used, for example, as upholstery, insulating material, Mattresses or used as a cosmetic product (cotton wool) become.
  • suction dryers air is in one Drying device in a direction transverse to the conveying direction sucked through the fiber composite. In such dryers satisfactory heat exposure to the fiber composite can be achieved across its entire thickness.
  • Such devices but have certain disadvantages.
  • To perform this procedure must be on one side of the fiber composite being conveyed a negative pressure can be generated. Heated air is on the suctioned opposite side from a chamber. Is to this chamber is provided with openings, for example slits, which run transversely to the conveying direction of the fiber composite. In order to it is ensured that the air through the fiber composite is sucked through, it is necessary to adjust the width of this Adjust openings to the width of the respective fiber composite.
  • Another type of such device is the device trained as a blow dryer.
  • a blow dryer Such a device is e.g. known from DE 30 23 229.
  • heated air is removed Blowing nozzles blown against the fiber composite.
  • blow dryers are combined with relatively thin fibers can be used satisfactorily.
  • the fiber composite is from one side blown hot air enters the fiber composite, but is reflected to some extent by this and again on the same side emerges from the fiber composite.
  • Treatment of thicker fiber composites therefore results in one middle area a zone which is not sufficient with Heat is applied and in which the binding fibers are not be melted sufficiently.
  • the fiber composite is therefore not solidified evenly over its entire thickness.
  • the device for strengthening the fiber composite Fiber composite continuously conveyed along a conveyor path.
  • the consolidation takes place by loading the fiber composite with warmth.
  • the device has at least one nozzle arrangement on.
  • the at least one nozzle arrangement is on at least one Arranged side of the conveyor path.
  • the nozzle arrangement is used for Blowing a heated treatment medium in the direction of the conveying path against the fiber composite.
  • a treatment medium typically uses air. But it would also be other treatment media conceivable.
  • the at least one nozzle arrangement has a plurality of adjacent blowing nozzles, i.e. the device is designed as a blow dryer.
  • the blow nozzles are spaced apart in a known manner, so that there is a space between each two adjacent blowing nozzles is formed.
  • the space between the blowing nozzles essentially closed towards the conveying path or lockable training. This ensures that the treatment medium is forced by the to pass through the entire thickness of the fiber composite. In this way uniform consolidation of the fiber composite guaranteed its entire thickness.
  • the gap it is not necessary close the gap completely airtight. It is sufficient to close the gap in such a way that between a pressure chamber is formed of the nozzle arrangement and the fiber composite is created in which an excess pressure is generated by means of the blowing nozzles can be.
  • the overpressure should be sufficiently large so that the treatment medium is forced through the entire fiber composite to pass through.
  • the invention exists So in it, a device for solidifying a continuously conveyed fiber composite so that a treatment medium even with a relatively thick fiber composite, typically more than 5 to 10 cm thick, through the entire thickness of the fiber composite can be blown through.

  • the blowing nozzles advantageously have a blowing opening which ends adjacent to the surface of the fiber composite.
  • the treatment medium can be blown directly into the fiber composite.
  • a rotating upper or lower belt between which the fiber composite is conveyed is used to convey the fiber composite in such a device.
