Definitions

  • the invention has for its object to find a method with which even finite goods such as prefabricated cushion and / or absorbent pads for diapers, wound dressings, compresses, pillows, possibly also plasters or the like. Finished products can be packaged continuously, without the products losing inadmissible volume and the cover fleeces connecting to the products during packaging needling.
  • the invention consists in that the middle layer later covering fleece first solidified with water jets, on this solidified fleece the middle layer to be enclosed, the finite, three-dimensional material applied, then these two layers are covered with another fleece, which was pre-consolidated in the same way, and all together to connect the hydrodynamic needles, in turn, are applied to the two covering fleeces lying on top of one another evenly over the working width.
  • the pre-consolidated cover fleeces have a density, load-bearing capacity and strength which do not adversely affect the products after the cover fleeces have been connected by means of the hydrodynamic needling.
  • the products can remain voluminous and in particular do not combine with the surface of the nonwovens that is already solidified in the structure of the nonwovens. It is a particular advantage that the cover fleeces have their own strength and do not roughen when in use, i.e. they have sufficient abrasion resistance.
  • the pre-consolidated nonwovens are provided with a perforated structure during consolidation, which occurs when the hydrodynamic consolidation takes place with a hole spacing in the nozzle strip of 5-20 hpi and a water pressure of at least 100 bar. This ensures good integration of the fibers of the cover fleece. If these so pre-consolidated nonwovens are placed on top of one another and provided with the finite products in between, and the further connection of the nonwovens for the final packaging of the products is preferably also carried out with a nozzle bar, the nozzle strips of which have holes of 5-20 hpi and the water pressure does not increase than 200 bar, then bond, then the fibers of the cover fleece intertwine in the areas around the products, but the products remain essentially unchanged in volume, each
