## Abstract

A method of forming an end of an elongated molding having an extruded length having a hollow interior defined by a base and a cover with at least one rib unitary with the base and extending toward the cover in supporting relationship therewith, wherein the base is first removed from the end portion which is then placed in a mold and formed by injection thermoplastic material therein.

## Claims

### Claim 1

An elongated molding having a hollow interior defined by an extruded base and an extruded cover, said base having at least one rib unitary therewith and extending from said base toward said cover in supporting relationship therewith, said molding having an end portion having a solid core, with said cover extending over said core to provide a continuous finished appearance to said molding.

### Claim 2 (depends on 1)

The elongated molding of claim 1 further comprising a plurality of ribs extending from said base toward said cover in supporting relationship therewith.

### Claim 3 (depends on 1)

The elongated molding of claim 1 wherein said cover is comprised of polyvinyl chloride.

### Claim 4 (depends on 1)

The elongated molding of claim 1 wherein said base and said at least one rib are separable from said cover at said end portion.

### Claim 5 (depends on 1)

The elongated molding of claim 1 wherein said end portion is formable into preselected shapes.

### Claim 6 (depends on 1)

The elongated molding of claim 1 wherein said base further comprises adhesive material for adhering said base to a supporting surface.

### Claim 7 (depends on 1)

The elongated molding of claim 1 wherein said cover further comprises a skin thereover.

### Claim 8

An elongated molding having a hollow interior defined by an extruded base and an extruded cover, said base having a plurality of ribs unitary therewith and extending from said base toward said cover in supporting relationship therewith, said cover further comprising a decorative skin thereover, said molding having an end portion having an injection molded solid core, with said cover and decorative skin extending over said core to provide a continuous finished appearance to said molding.

### Claim 9 (depends on 8)

The elongated molding of claim 8 wherein said cover is comprised of polyvinyl chloride.

### Claim 10 (depends on 8)

The elongated molding of claim 8 wherein said plurality of ribs are separable from said cover.
