  • Method and device for partially applying a surface coating and breathable film with such a partial surface coating
    Patent number: 7329622
    Abstract: A vapor permeable, water impermeable film is coating partially with an adhesive surface coating. The partial adhesive coating is deposited on both surfaces of the film and coated areas on one surface of the film are at least partially in line with the coated areas of the second surface. A three ply laminate sheet is manufactured having a middle layer consisting of a vapor permeable water impermeable films having partial surface coating with an adhesive material on both surfaces.

  • Device and method for applying coating material
    Patent number: 6827785
    Abstract: In a device for depositing coating material with the manufacture of coated and/or impregnated sheet formations the thickness of the coated sheet formation is monitored with two metering rollers (11, 13) rotating against the sheet formation. The distance measurement between the contact surfaces (12, 14) of the metering rollers (11, 13) is carried out by way of measuring surfaces (16, 18) concentric to the metering rollers (11, 3) which have a smaller diameter (d1) than the contact surfaces (12, 14).
