ABSTRACT:
Panel construction for forming upholstery panels for use in automotive vehicles and the like, where a plastic substrate which has been formed to a desired configuration, is placed over a grounded metal horn, a layer of adhesive fabric is placed over the substrate, a layer of heat bondable foam is placed over the adhesive fabric, a cover layer is placed over the foam, heat seal punches connected to the positive output of a source of electrical energy are selectively brought in horizontally on all sides of the panel perimeter to successively compress the cover and foam against the sides of the substrate. Electrical energy is applied to the heat seal punches when in selective engaged position to melt the adhesive and the foam, and fasten the cover to the substrate. The punches are withdrawn and the completed panel is removed from the horn.
