Abstract
Abstract A trim molding for attachment to a vehicle includes a core member having an outer periphery less than a predetermined thickness. An end is formed at each end of the core member. An outer layer is molded about one side of the core member and ends to form a smooth continuous surface to the predetermined thickness and to prevent a joint line from visually appearing between the ends and the core member in the outer layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A method of making a trim molding for attachment to a vehicle, said method comprising the steps of: forming an elongated core member by extruding and cutting a polymeric material to an outer periphery and length less than a predetermined thickness and length; forming an end at each end of the core member; molding an outer layer of a polymeric material about at least a portion of one side only of the core member and over said ends to form an outer elongated layer over the core member to the predetermined thickness and to provide a smooth continuous surface from one of said ends to the other of said ends to thereby prevent a transverse joint line from visually appearing in the outer elongated layer between the ends and the core member.
Claim 2
Independent Claim
132 words
A method of making a trim molding for attachment to a vehicle, said method comprising the steps of: forming an elongated core member by extruding and cutting a polymeric material to an outer periphery and length less than a predetermined thickness and length; forming an end at each end of the core member; molding an outer layer of a polymeric material about at least a portion of one side only of the core member and over said ends to form an outer elongated layer over the core member to the predetermined thickness and to provide a smooth continuous surface from one of said ends to the other of said ends to thereby prevent a transverse joint line from visually appearing in the outer elongated layer between the ends and the core member.
Claim 3
Dependent Claim
53 words
A method as set forth in claim 1 including the step of securing an elongated bright strip with lateral edge portions onto said core member and molding said outer elongated layer over only said lateral edge portions of said bright strip thereby leaving a central portion of said bright strip exposed to view.
Claim 4
Dependent Claim
23 words
A method as set forth in claim 2 wherein said step of molding the outer elongated layer is carried to by injection molding.
Claim 5
Independent Claim
98 words
A method of making a trim molding for attachment to a vehicle, said method comprising the steps of: extruding a core member to an outer periphery less than a predetermined thickness said core member having a bright area; forming an end at each end of the core member; injection molding an outer layer about one side only of the core member to fill the space between the bright area and outer periphery of the core member to form a smooth continuous surface and to prevent a transverse joint line from appearing between the ends and the core member.
Claim 6
Independent Claim
98 words
A method of making a trim molding for attachment to a vehicle, said method comprising the steps of: extruding a core member to an outer periphery less than a predetermined thickness said core member having a bright area; forming an end at each end of the core member; injection molding an outer layer about one side only of the core member to fill the space between the bright area and outer periphery of the core member to form a smooth continuous surface and to prevent a transverse joint line from appearing between the ends and the core member.
