Abstract

Un material extruible, por ejemplo un adhesivo de aplicación en caliente, se aplica a un substrato con irradiación simultánea de un haz lasérico. La energía del láser es absorbida por el adhesivo y el substrato para hacer que el adhesivo se extienda en la estructura. Cuando se aplica a un espacio de separación entre dos hojas o panos de substrato, el material extruible produce una unión muy fuerte. Cuando uno de los materiales del substrato es poroso, el material extruible penetrará en el espesor del material y se pondrá en contacto con una capa inferior para formar una unión. El material extruible se aplica a través de una tobera y el haz lasérico se dirige a través de la tobera para mantenerse coaxial con el trayecto del flujo del material extruible. La disposición coaxial facilita el movimiento de la tobera y el haz siguiendo figuras complicadas y garantiza la aplicación simultánea del material extruible y del haz lasérico.An extrudable material, for example a hot-applied adhesive, is applied to a substrate with simultaneous irradiation of a laser beam. The laser energy is absorbed by the adhesive and the substrate to make the adhesive spread on the structure. When applied to a gap between two sheets or panels of substrate, the extrudable material produces a very strong bond. When one of the substrate materials is porous, the extrudable material will penetrate the thickness of the material and contact a bottom layer to form a bond. The extrudable material is applied through a nozzle and the laser beam is directed through the nozzle to remain coaxial with the flow path of the extrudable material. The coaxial arrangement facilitates the movement of the nozzle and the beam following complicated figures and guarantees the simultaneous application of the extrudable material and the laser beam.
