  • Process and installation for the production of foam in a continuous foaming process
    Patent number: 8389590
    Abstract: The invention relates to an installation and to a process for the production of foam in a continuous foaming process with the following steps, measuring actual surface temperatures of the foam or the facing layers along a conveying direction and determining a control variable for the foaming process as a function of a deviation of the actual surface temperatures from the nominal surface temperatures.
    Type: Grant
    Filed: December 6, 2005
    Date of Patent: March 5, 2013
    Assignee: Bayer Intellectual Property GmbH
    Inventors: Hubert Ehbing, Holger Zien, Rainer Rauhaus, Johann Frei
  • Process and apparatus for the optimized production of foam in a continuous block slabstock process
    Patent number: 7645809
    Abstract: The invention relates to a plant and a process for the production of foam in a continuous slabstock process in which the actual foam height profile is detected transversely to the feed direction and a correcting variable for the slabstock process based on deviation of the actual foam height profile from a desired foam height profile is determined.
    Type: Grant

  • Process and installation for the production of foam in a continuous slabstock foam process
    Patent number: 7138077
    Abstract: The invention relates to an installation and a process for the production of foam in a continuous block foam process in which the height of a foam-forming mixture along a conveyor is measured and a correcting variable as a function of deviation of the actual height risen from the standard height is determined.
