Abstract: A method of producing a molding which includes the steps of interconnecting the first and second moldings, each of which includes a core, by a connecting portion which has a decorative trim portion with a continuously varying cross sectional shape; forming a notched portion with at least one concave portion and at least one convex portion on the core of each of the first and second moldings; engaging the respective notched portions of the first and second moldings with each other by setting the concave portion of the first molding in the convex portion of the second molding; disposing the engaged portions within a cavity of a mold having a cross sectional shape corresponding to the cross sectional shape of the connecting portions; and injecting a material for molding into the cavity of the mold so as to form a decorative trim portion around the engaging portions, which continuously connects the first and second moldings as one body.

Abstract: A molding having connection with high strength, which comprises: two moldings connected with each other, each of the two moldings including a decorative trim portion as an outer part and being provided therein with a core material having a notched portion with at least one concave portion and at least one convex portion; and a connecting portion for connecting the two moldings, the connecting portion including a connecting decorative trim portion of which the cross sectional shape is continuously varied so as to continuously connect the cross sectional shapes of the two moldings; the respective notched portions of the two moldings being engaged with each other, and the periphery of the engaged portions being molded into one body as the connecting decorative trim portion so as to form the connecting portion. And a method of producing the same.
