ABSTRACT:
A dual applicator for simultaneously applying a polyurethane adhesive and sealant and a foam dam to a motor vehicle window or windshield and a robot arm capable of translating and/or rotating the applicator relative to the glass. The applicator includes a first nozzle for discharging the polyurethane through a shaped opening which defines a first plane and a second nozzle adjacent to and offset from the first nozzle. The first nozzle discharges polyurethane in a first bead as the applicator or glass is translated and the second nozzle discharges the foamable material in a second bead adjacent to and spaced from the first bead.
