In the rear window molding 5 after being mounted, the decorative portion 52 is continuously and integrally formed over the entire length, so that good design is obtained.

An apparatus for manufacturing such a rear window molding 5 for an automobile will be described below. The material of the metal molding unwound from a coiler (not shown) is supplied to an extrusion die device through a position detection device, an adhesive application device and an induction baking device while being bent into the above-described shape by a forming roll. It is extruded integrally with the resin material or the rubber material in the above-mentioned cross-sectional shape. The extruded molding material is sent to a cutting device by a take-off machine through a cooling tank, where the material is cut to a predetermined length.

At this time, the feed amount of the metal support detected by the position detection device is applied to the control device, and the operation timing of the extrusion die device and the cutting device is determined based on the input signal. Then, an operation signal is output from the control device to each device. The position of the position detecting device may be any position as long as it can detect the amount of movement or the amount of movement of the material.

The molding die provided in the extrusion die apparatus is, for example, as shown in FIGS. 4 to 9, a second die arranged in the molding extrusion direction (perpendicular to the paper surface). 11 and a first die 12, and a third die 13 disposed inside an extrusion opening defined by the second die 11 and the first die 12. The second die 11 is installed in a fixed state,
An extruded side having a shape corresponding to the contour shape of the rear window molding 5 is provided. The extrusion side of the second die 11, defined by the shaped side portion forming the outer shape corresponding to the mounting portion 51 of the under-molding 5A described above

Extrusion molding of the undermolding 5A having a ( shape) is performed.

Next, in the change extrusion step of forming the corner molding 5C continuous with the under molding 5A, as shown in FIGS. 6 and 7, the first die 12 is moved upward with respect to the second die 11 in the drawing. Extrusion is performed while being moved away. In this changing portion extrusion step, an extrusion molding port that changes in accordance with the cross-sectional shape of the corner molding 5C is defined by the second die 11 and the first die 12, and the third die 13 is It is retracted to the back in the extrusion direction of the molding. This extrusion molding of the corner molding 5C as shown in Figure 10, Wei the outer surface shape of the decorative section 52 at a constant
It is performed while holding . In addition, corner molding 5C
The extruded product 5C 'corresponding to the mounting portion of the undermolding 5A that is extruded together with the extruded product is removed as an unnecessary portion as described later.

Furthermore side of the side molding 5B
In the case of performing split flow extrusion in the partial extrusion step , FIG.
As shown in FIG. 9, first, the first die 12 is held in the most separated state with respect to the second die 11, and the third die 13 is inserted into the extension region of the extrusion opening formed at that time. To enter. In the shunt extrusion step in the side portion extrusion step, extrusion port constant shape corresponding to the side molding 5B is, when defined by the second die 11 and third die 1 3 At the same time, the third die By 13, the branch extrusion is performed while the extrusion port substantially corresponding to the undermolding 5A is divided from the extrusion port corresponding to the side molding 5B. Therefore, according to the split flow extrusion, the extrusion molding of the side molding 5B corresponding to the under molding 5A is performed while the extrusion molding of the side molding 5B as the second cross-sectional shape is performed.
Is extruded while being separated from the side molding 5B.

The rear window molding material thus extruded is cut to a fixed size by a cutting device (not shown), and then cut along the line XX in FIG. Is removed. In other words, the corner extrusion 5C
The extruded product 5C 'corresponding to the undermolding 5A extruded together with the extruded product 5B corresponding to the undermolding 5A extruded while being separated from the side molding 5B by the split flow extrusion process.
'Is removed as an unnecessary portion as shown in FIG. 11 by the above removing step. When the molding is mounted, the corner molding 5C is bent.
