  • Patent number: 8512805
    Abstract: A method for dispensing a foamed material onto a substrate surface, including: generating a relative movement between a substrate surface and a material dispensing apparatus exit opening, mixing at least two material components in a mixing device, generating a pressure differential between the mixing device and a dispensing region, conveying the dispensing material from the mixing device to the exit opening, and discharging the dispensing material from the exit opening onto the substrate surface.
    Type: Grant
    Filed: March 9, 2012
    Date of Patent: August 20, 2013
    Assignee: Nordson Corporation
    Inventors: Ronald Burger, Frank Jones, Dirk Pannhausen

  • Patent number: 8156889
    Abstract: A method for dispensing a foamed material onto a substrate surface, including: generating a relative movement between the substrate surface to be coated and an exit opening of a material dispensing apparatus, mixing at least two material components in a mixing device to provide a free-flowing, foamable dispensing material, generating a pressure differential between the mixing device and the dispensing region located downstream in the direction of flow from a discharge cross-section of the exit opening, conveying the dispensing material from the mixing device for the dispensing material to the exit opening, and discharging the dispensing material from the exit opening onto the substrate surface. The dispensing material be kept under such a pressure in the region adjacent to and upstream from the discharge cross-section of the exit opening that the dispensing material in this region has a foaming rate that is less than 10% of the foaming rate which ensues at the end of the foaming process.
