  • Method and device for applying high viscosity liquids
    Patent number: 6858249
    Abstract: Method for partially applying high viscosity liquids to a supporting material whereby the liquid is applied by means of a nozzle which opens into an orifice, and is extruded through a screen on to the supporting material, which rests on a pressure-resistant substrate, but distinguished by the geometry of the nozzle being so arranged that the nozzle outlet slit opens into an orifice which feeds the liquid to the screen, and in that orifice an increase of pressure in the liquid is generated so that the pressure in the liquid at the nozzle orifice is higher than the pressure in the nozzle outlet slit.

  • Method for applying liquid, pasty or plastic substances to a substrate
    Patent number: 6852366
    Abstract: Method for applying liquids, in particular thermoplastics, to a substrate, whereby the substance is melted, heated and by means of a nozzle or doctor blade is passed through a perforated cylinder on to a supporting material, distinguished by the perforated cylinder being heated in the arc segment where the liquid passes through, which arc segment covers an angle of up to 180°, preferably between 5° and 90° in relation to the center point of the screen.
