  • Patent number: 8475611
    Abstract: The present invention relates to a method and a device for the application of a strip material to a substrate. Particularly, the present invention relates to a automatic application of an elongate strip of elastic material to a substrate. The present invention further relates to a device and a method for applying a seal strip such as a weatherstrip seal to a substrate. The elongate strip is advanced by drive means and positioned on a substrate by means of an application unit. The stress of the elongate strip is controlled by a stress control unit which is positioned in the area between the drive means and the application unit.
