ABSTRACT:
The invention provides a method of applying a veneer to a substrate having edges with a compound curve. The invention includes the steps of trimming the veneer to provide a peripheral margin and applying a stretchable releasable adhesive tape to the margin, applying an adhesive to the surfaces of the substrate, positioning the veneer over the substrate and securing the veneer in position, and subjecting the veneer to a substantially uniform pressure over the substrate. An embodiment for convex edges provides the further steps of providing one or more v-shaped relief cuts converging where the curved edge surface meets the main surface and applying a releasable adhesive tape to retain a butt joint between the edges of each relief cut. An embodiment for concave edges provides the further steps of providing one or more slits extending into the margin of the veneer parallel to the direction of the grain and applying a releasable adhesive tape over the relief cuts. The invention thus permits a single sheet of veneer to be applied over the main and edge surfaces of furniture and the like having concave or convex rounded or bullnose edges.
