ABSTRACT:
A molding method which provides a relatively simple structure, while also providing a pleasing appearance which is adaptable to a variety of ornamental and artistic applications. The molding is produced by extruding an ornamental core, and joining trimming portions to the sides of the ornamental core. Where the ornamental core and trimming are formed of materials which can be readily joined together, the trimming is melt bonded directly to the side surfaces of the ornamental core. Alternatively, a foil laminate can be provided, and the ornamental core is joined to an upper layer of the foil laminate, with the trimming joined to a lower layer of the foil laminate. If desired, the width of the ornamental coil can be changed during extrusion molding, such that the width varies along the longitudinal direction of the molding.
