Gino Antolini has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus and a process for washing continuously wet-spun elastane
    Patent number: 5813068
    Abstract: This invention relates to a new washing apparatus for the continuous production of elastane filaments which are produced by a wet-spinning process, which essentially consists of a stripping unit (10) and a washing unit (11) which are disposed in steps above the precipitation bath (1) of a wet-spinning device.
    Type: Grant
    Filed: December 15, 1995
    Date of Patent: September 29, 1998
    Assignee: Bayer Faser GmbH
    Inventors: Ulrich Reinehr, Gunter Turck, Tilo Sehm, Wolfgang Anderheggen, Toni Herbertz, Gino Antolini
  • Process for preparing multifilament, wet-spun elastane threads
    Patent number: 5756205
    Abstract: The invention relates to a process for preparing multifilament, wet-spun elastane threads with increased spinning output, which is achieved by largely removing entrained water from the filaments after leaving the spinning bath and then fixing the threads on at least two rollers at a temperature of at least 200.degree. C. for at least 3 seconds.
    Type: Grant
    Filed: March 13, 1997
    Date of Patent: May 26, 1998
    Assignee: Bayer Faser GmbH
    Inventors: Ulrich Reinehr, Gunter Turck, Tilo Sehm, Wolfgang Anderheggen, Toni Herbertz, Gino Antolini
  • Process for adjusting the viscosity of highly concentrated elastane solutions for the dry spinning or wet spinning of elastane fibres
    Patent number: 5741867
    Abstract: The invention relates to a process for adjusting the viscosity of highly concentrated elastane solutions by reaction of the solution with secondary aromatic amines in order to produce spinning solutions for the dry or wet spinning of elastane fibres.
