A method of preparing a vehicle panel assembly for attaching the panel to a vehicle is disclosed which provides a “ready-to-install” panel assembly. The panel assembly includes first and second spaced sides, with the bead of heat activated adhesive provided on the second side of the panel. The panel and bead are heated preferably by applying shortwave and longwave infrared radiation, with the shortwave infrared radiation being applied to an adhesive free side of the panel to heat the panel and, thereby, indirectly heat the bead of the heat activated adhesive. The longwave infrared radiation is applied to the adhesive side of the panel to directly heat the bead and thereby activate the adhesive. The ready-to-install adhesive may be applied on or adjacent to a gasket, such as a polyvinyl chloride (PVC) molding, a urethane molding, or the like. Optionally, either during or after heating, the substrate is cooled in order to ease handling of the panel assembly after the bead of adhesive is activate and ready for installation.
An apparatus for activating a heat activated adhesive for attaching a vehicle window panel to a vehicle, the vehicle window panel having first and second opposed and spaced apart surfaces and a bead of heat activated adhesive on the second surface, said apparatus comprising:
An apparatus for activating a heat activated adhesive for attaching a vehicle window panel to a vehicle, the vehicle window panel having first and second opposed and spaced apart surfaces and a bead of heat activated adhesive on the second surface, the vehicle window panel being supported on a conveyor, and the conveyor conveying the vehicle window panel between a plurality of heating stages, said apparatus comprising:
An apparatus for activating a bead of heat activated adhesive on a vehicle window panel assembly for attaching the window panel assembly to a vehicle, the vehicle window panel assembly including a substrate having first and second opposed and spaced surfaces, the bead of heal activated adhesive provided on the second surface of the substrate and including a central core portion, an outer skin portion, and an interface portion on the second surface of the substrate, said apparatus comprising:
