An elongate composite member (1) suitable for a vehicle ornamental member comprises an elongate shaped body (2) having a common cross-section part (2b) with a longitudinally constant cross-sectional shape, and a varying cross-section part (2a) with a longitudinally varying cross-sectional shape. A resin part (3) is formed by extrusion molding along the varying cross-section part (2a) to continuously extend in the longitudinal direction, thereby realizing an excellent overall appearance. Such elongate composite members (1) can be readily and continuously manufactured basically with an extrusion molding process, wherein the elongate shaped body (2) is continuously and longitudinally fed into an extrusion die assembly (26) comprising a stationary die (31) and the movable die (32), through which the common cross-section part (2b) and the varying cross-section part (2a) are respectively passed in the longitudinal direction. The movable die (32) is moved in a direction intersecting the passing direction of the elongate shaped body (2) , in which the varying cross-section part (2a) varies during its passage in the longitudinal direction. At the same time, a resin is extruded from an extrusion orifice in the movable die, so that the elongate shaped body (2) is formed with the resin part (3) extending continuously in the longitudinal direction.

Un élément composite allongé (1), utilisable comme élément décoratif pour des véhicules, a un corps moulé allongé (2) ayant une portion (2b) dont la section transversale est sensiblement constante dans la direction longitudinale et une portion (2a) dont la section transversale est variable dans la direction longitudinale. Une portion de résine (3), s'étendant d'une manière continue dans une direction longitudinale, est extrudée et moulée sur la portion à section transversale variable (2a), pour constituer un élément intégré ayant un aspect esthétiquement plaisant. Pour réaliser facilement et en continu ces éléments composites allongés (1) par moulage par extrusion, le corps moulé allongé (2) est amené en continu à un moule d'extrusion (26) qui est pourvu d'un moule stationnaire (31) et d'un moule mobile (32), suivant la direction longitudinale, avec la portion à section transversale constante (2b) correspondant au moule stationnaire (31) et la portion à section transversale variable (2a) correspondant au moule mobile (32). En outre, pendant que le moule mobile (32) se déplace dans une direction transversale par rapport à la direction suivant laquelle le corps moulé allongé (2) se déplace et suivant laquelle la portion à section transversale variable (2a) varie et en maintenant le passage de la portion à section transversale variable (2a) dans la direction longitudinale, la résine est extrudée depuis un orifice d'extrusion formé dans le moule mobile (32) pour assurer le moulage d'une pièce de la portion de résine s'étendant longitudinalement (3) avec le corps moulé allongé (2).
