    Type: Application
    Filed: November 26, 2003
    Publication date: July 13, 2006
    Inventors: Uwe Bornmann, Heinz Schorgenhuber, Franz Hintermuller
  • Method for the production of geotextiles from melt-spun fibers
    Publication number: 20060150377
    Abstract: The invention relates to a method for the production of geotextiles from melt-spun fibers. The melt-spun endless fibers are continuously transported in an unimpeded manner on a screen belt along all hardening and post treatment zones.
    Type: Application
    Filed: November 26, 2003
    Publication date: July 13, 2006
    Inventors: Uwe Bornmann, Albert Mittermayr, Alois Punkenhofer
  • Method for producing geotextiles with a defined isotropy from melt-spun filaments
    Publication number: 20060137808
    Abstract: The invention relates to a method for producing geotextiles with a defined adjustable isotropy, particularly of the mechanical properties in the longitudinal transverse direction.
    Type: Application
    Filed: November 26, 2003
    Publication date: June 29, 2006
    Inventors: Uwe Bornmann, Heinz Schorgenhuber, Klaus Ahm
  • Process for producing spunbonded webs
    Patent number: 5538682
    Abstract: A spunbonded web is produced by melting a thermoplastic polymer to form a melt, spinning the melt downwardly through spinnerets to form filaments, cooling the filaments, drawing the thus cooled filaments by take-off nozzles into the form of filament strands, passing the filament strands through guide tubes and by the guide tubes directing the thus guided filament strands downwardly therefrom toward a laydown apparatus, and laying down the filament strands in the form of a web on the laydown apparatus and moving the web in a take-off direction. Adjacent of the filament strands are guided, due to orientation of respective adjacent guide tubes thereof in different downward directions at respective different angles relative to the takeoff direction, to the laydown apparatus in respective different directions at said respective different angles.

    Assignee: Polyfelt Gesellschaft m.b.H.
    Inventors: Uwe Bornmann, Manfred Winkler, Heinz Schorgenhuber
  • Process for controlling the anisotropy of spunbonded webs
    Patent number: 5525286
    Abstract: Process for controlling the anisotropy of the mechanical properties of spunbonded webs through variation of the frequency of vibration of impingement panels at web laydown.
    Type: Grant
