Creating water-tight connection between layers of textiles, involves use of laser ray to melt adhesive layer

The invention relates to a method for producing a fluid-tight connection of layers of material, especially of textile fabrics, according to which an adhesive layer of an additional sealing strip (8) sealing the layers of material or one of the layers of material (1, 2) is molten by means of a laser...

More Information
Summary:The invention relates to a method for producing a fluid-tight connection of layers of material, especially of textile fabrics, according to which an adhesive layer of an additional sealing strip (8) sealing the layers of material or one of the layers of material (1, 2) is molten by means of a laser beam (10). The sealing strip and the layer of material are then linked with the layers of material and the other layer of material, respectively. Between the laser beam (10) and the sealing strip (8) or the layer of material a relative movement takes place. Bei einem Verfahren zur Herstellung einer flüssigkeitsdichten Verbindung von Materiallagen, insbesondere von textilen Stoffen, wird mittels eines Laserstrahls eine Klebeschicht eines die Materiallagen abdichtenden, zusätzlichen Dichtbandes oder eine der Materiallagen aufgeschmolzen. Darauf wird das Dichtband oder die eine Materiallage mit den Materiallagen oder der anderen Materiallage verbunden. Zwischen dem Laserstrahl und dem Dichtband bzw. der Materiallage findet eine Relativbewegung statt.
