Abstract
A molding having a relatively simple structure, but which provides a pleasing appearance which is adaptable to a variety of ornamental and artistic applications. The molding includes an ornamental core which varies in width along the longitudinal direction of the molding, with a trimming attached to the sides of the ornamental core. The overall width of the molding (including the ornamental core and trimming) varies along the longitudinal direction of the molding corresponding to the varying width of the ornamental core. In addition, merging portions or sections are provided at which the trimming merges together, with the ornamental core not visible or not present at such portions.
Claims22
A molding comprising:
- an extrusion molded elongated ornamental core having an exposed surface, two side surfaces and a rear unexposed surface;
- a laminated foil including an upper layer adhered to said rear unexposed surface of said ornamental core, said laminated foil further including a lower layer;
- and
- an extrusion molded elongated trimming extending along the two side surfaces of said elongated ornamental core, said trimming further extending along and adhered to said lower layer of said laminated foil;
- wherein said ornamental core is melt bonded directly to said upper layer of said laminated foil with a melt bond directly between a material of said ornamental core and a material of said upper layer of said laminated foil, and further wherein said lower layer of said laminated foil is directly melt bonded to said trimming with a melt bond directly between a material of said lower layer of said laminated foil and a material of said trimming.
A molding comprising:
- an extrusion molded elongated ornamental core having an exposed surface, first and second side surfaces and a rear unexposed surface;
- an extrusion molded elongated trimming including first and second portions extending respectively along said first and second side surfaces of said extrusion molded ornamental core, wherein said molding includes a first section having said exposed surface of said ornamental core, said molding further including a second section adjacent to said first section, wherein said second section does not include an exposed surface of an ornamental core, and wherein said first and second portions merge to form a single third portion at a juncture of said first and second sections such that said single third portion is provided in said second section, and said single third portion extends along a length of said second section, and further wherein said first and second portions of said trimming are extrusion molded together and merged together at said juncture during extrusion molding of said first, second and third portions such that said trimming extends continuously along said first and second sections and through said junction
- wherein said ornamental core and said trimming are also extrusion molded together such that said extrusion molded ornamental core is directly connected to said trimming by a melt bond between a material of said ornamental core and a material of said trimming.
A molding comprising:
- an extrusion molded ornamental core having an exposed surface, first and second side surfaces and a rear unexposed surface;
- an extrusion molded elongated trimming including first and second portions respectively extending along said first and second side surfaces of said extrusion molded ornamental core;
- wherein a width of said elongated ornamental core varies along a longitudinal direction of the molding, and wherein an overall width of the molding including the ornamental core and elongated trimming varies along the longitudinal direction of said molding corresponding to the varying width of said ornamental core, and further wherein the elongated ornamental core and the elongated trimming are joined together during extrusion molding of said elongated ornamental core and said elongated trimming with said first and second portions of said trimming directly melt bonded to said first and second side surfaces of said ornamental core with a melt bond directly between a material of the ornamental core and a material of the trimming.
