(Extrusion Molding Step) When the glass surface of the window glass 3 sucked by each suction cup 63 of the panel holding device 60 is a curved surface, the window on the side facing the side opening of the die device 11 is used. The holding arm 62 of the panel holding device 60 and the window glass 3 are tilted together with the tilting table 57 so that the lower edge portion of the glass 3 is horizontal. Further, the moving device 24 is adjusted up and down so that the lower edge of the peripheral edge of the window glass 3 is at a height position corresponding to the side opening of the die device 11.

Here, the slide table 26 is advanced,
A substantially central portion of the lower edge of the window glass 3 held by the panel holding device 60 is inserted into the extrusion molding port from the side opening of the die device 11 by a predetermined amount. At this time, the second die 132 of the die device 11 is set at the position shown in FIG. 7, and the extrusion opening is enlarged to the maximum opening area. And as mentioned above, wind glass 3
Is inserted into the extrusion molding opening, so that a molding space corresponding to the cross-sectional shape of the molding 4 is formed between the periphery of the window glass 3 and the inner peripheral wall of the extrusion molding opening. When this molding space is formed, the molding material P is supplied to the material feeding path of the die device 11, and the material P
Is extruded from the extrusion port through the molding space.

From the extrusion port, the molding material P
Are extruded, the first and second pivot arms 36, 41
Are turned in predetermined directions, and the lower edge of the periphery of the window glass 3 is moved at a controlled speed. Thus, as shown in FIGS. 8 and 9, the molding 4 is sequentially extruded from the central portion of the lower edge of the periphery of the window glass 3 toward the first corner portion. At this time, the above-described tilting is continuously performed in accordance with the curvature of the curved surface of the window glass 3, whereby the angle between the extrusion opening of the die device 11 and the peripheral edge of the window glass 3 is reduced. A molding space corresponding to the cross-sectional shape of the molding 4 is continuously maintained at a constant level.

As shown in FIG. 9, when the first corner of the periphery of the window glass 3 reaches the position of the extrusion molding opening of the die device 11, the first and second revolving arms 3 are moved.
The turntable 48 is rotated at the same time as the turning of the wheels 6 and 41, and the die device 11 is relatively moved along the round surface of the first corner portion of the window glass 3. Further, since the tilting table 57 is tilted in accordance with the curvature of the glass surface at the first corner portion, the first corner portion of the window glass 3 is kept horizontal with respect to the extrusion opening of the die device 11.

The tilting table 57 is tilted in accordance with the curvature of the right edge of the peripheral edge of the window glass 3, and the right and left edges of the peripheral edge of the window glass 3 are kept horizontal with respect to the extrusion molding port, while the first and second tilting tables 57 are kept. Revolving arms 36, 41 of
As a result, the right edge of the periphery of the window glass 3 is moved.
Then, a side molding 4C of the molding 4 is extruded on the right edge of the window glass 3. Also at this time, the above-described tilting is continuously performed in accordance with the curvature of the curved surface of the window glass 3, whereby the gap between the extrusion opening of the die device 11 and the peripheral portion of the window glass 3 is increased. Is constantly maintained constant, and a molding space corresponding to the cross-sectional shape of the wind molding 4 is continuously formed.

In the side portion from the upper right end of the window glass 3 to the second corner portion, the second die 132 of the die device 11 is moved from the position shown in FIG. 7 to the position shown in FIG. The extrusion is performed while being moved, and the corner molding 4B is extruded while the bulging wall thickness of the molding 4 is reduced while the shape of the exterior surface of the decorative portion 6 is kept constant. In this case, the movement of the second die 132 is controlled so as to synchronize with the relative movement between the window glass 3 and the die device as described above.
Accordingly molding having a predetermined cross-sectional shape corresponding to each part of the window glass 3, precisely shaped without causing a positional shift, especially in the corners and in the vicinity thereof, a strange膨肉portion of the corner molding 4 B It is designed to be molded with high positional accuracy.

After the extrusion of the corner molding 4B is completed, the upper edge of the periphery of the window glass 3 is
After reaching the first extrusion port, the upper molding 4A is extruded. In this case, the die device 11
The second die 132 is set at the position shown in FIG. 6, and the extrusion opening is reduced to the minimum opening area.

The peripheral portion of the window glass 3 thus held by the panel holding device 60 is
While being kept horizontal by 4, it is always inserted into the extrusion molding opening of the die apparatus 11 at a constant insertion depth and moved. At this time, since the second die 132 provided in the die device 11 is controlled so as to be synchronized with the relative movement between the window glass 3 and the die device, the outer shape of the extrusion opening is set in accordance with the glass position. Extrusion is performed while changing. As a result, a molding 4 having a different cross-sectional shape depending on each part is accurately extruded and formed on the periphery of the window glass 3 without displacement, and at the same time, the window glass 3 is coated with an adhesive applied to the periphery of the window glass 3. The molding 4 is integrated and adhered to the peripheral edge of. When the entire length of the molding 4 is extruded along the peripheral portion of the window glass 3, the supply of the molding material P to the material supply path of the die device 11 is temporarily stopped.

(Advancing Step) When the supply of the molding material is cut off, the slide table 26 is retracted to the original position. And the window glass 2 with a molding is pulled out from the side opening part of an extrusion molding opening. Thereafter, the window glass 2 with the molding is placed on the pair of panel receiving arms 101 of the panel unloading shelf device 103 by the panel unloading device 95.
