Definitions

  • the invention relates to structured guide plates for depositing filaments in a process for the production of geotextiles.
  • Baffles are known to be used to store melt-spun filaments for the production of a non-woven fleece used. If necessary, these are filed on a pad Filaments then by needling, for example by Water jet needling solidified.
  • AT 399 169 B describes a method for controlling the anisotropy of the Nonwoven properties in the longitudinal and transverse directions are known, in which the Vibration frequency of the guide or baffle plates when the threads are deposited in Depending on the desired ratio of anisotropy is varied.
  • the object of the invention was to provide baffles or baffles their structuring allows defined variations in the filing structure.
  • the invention therefore relates to structured baffles, characterized by the fact that they are formed by groove-shaped, wavy, waffle-shaped, segment-shaped, diamond-shaped structures in longitudinal and / or transverse direction are structured.
  • defined storage structures can be created be achieved, the final properties of a subsequent solidified geotextile.
  • the influence in the baffle realized the two-dimensional fanning out of the structures Filament bundle.
  • the correspondingly structured guide plates preferably have longitudinal or Cross grooves on, in the surface of the baffles or baffles in one defined vertical or vertical spacing recesses are 1-20 mm below the thickest point of the baffle or baffle.
  • the depth of the recesses also influences the filing structure of the Filaments. The deeper the recesses, the greater the maximum thickness of the Baffles in relation to the depth of the recesses.
  • the structured baffles advantageously have a longitudinal or Transverse structures in the form of a segment of a circle or wavy Structures on.
  • isotropy i.e. the ratio of Longitudinal strength is influenced by transverse strength
  • the fleece deposited in the manner according to the invention can then be opened are solidified in the usual way, using both known needling methods as well as hydroentangling processes can be used.
  • a method for solidification is used particularly advantageously be, in which the filaments in a manner according to the invention on a Sieve belt are deposited, which then the deposited filaments at least in transported the first consolidation stage
  • melt-spun filaments are therefore initially open deposited and on the endless screen belt according to the invention transported to the first consolidation stage.
  • the filed Filaments are passed through on the sieve belt during transport Suction zones fixed, so that no disturbances during transport of the unconsolidated Filaments can occur.
  • the water jets act depending on the arrangement serves the solidification device through the sieve belt and / or the sieve belt as a base.
  • the geotextile After hardening in the first hardening stage, the geotextile is sufficiently hardened so that it can be guided without disturbing the structure, even without the support of a conveyor belt. If necessary, the sieve belt can also be passed through any further consolidation stages.
  • the geotextiles produced in this way are characterized by large Homogeneity and uniformity and its defined mechanical Properties in the longitudinal and transverse directions.
  • the geotextiles produced according to the invention can therefore in particular for fastening, as a substructure or drainage installation in streets, paths, Bridges, airport runways, embankments, dams and the like are used become.
  • 1 a and 1 b show guide plates with modified wave structures, 1 c with transversely oriented fine wave structure, 1 d with transversely oriented corrugated structure, 1e with wave structure, 1 f shark skin structure, 1 g with scale structure, 1 h with two-dimensional corrugated structure, 1 i with longitudinal stripe structure and 1 j with cross-oriented semicircular structure.
