BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) FIGS. 1 to 8 show Embodiment 1 of the present invention.
It is explained according to. 1 to 5, the window panel 10 is formed in a required shape from a glass plate or a transparent synthetic resin plate (in FIG. 5, a substantially triangular shape is illustrated, but may be a substantially trapezoidal shape, a square shape, or the like). I have. At the peripheral edge of the wind panel 10, the molding 30 is attached by being extruded and simultaneously joined so as to cover the end face 11 and both the front and back surfaces near the end face 11. The top surface 35 of the molding 30 is substantially flush with the surface of the window panel 10 so that the molding 30 is mounted on the peripheral edge of the window panel 10. The front side chamfer 12 is formed by chamfering or the like. In the first embodiment, a back side chamfer 13 is also formed on the back side of the end face 11 of the wind panel 10.

The molding 30 includes a molding body 31 that extends from the boundary between the end face 11 of the wind panel 10 and the front side chamfer 12 to the back side of the wind panel 10, the end face 11 of the wind panel 10 and the front face. A top portion 34 is integrally provided with a portion extending from a boundary portion with the take portion 12 to a top surface 35. The molding main body 31 is joined from the boundary between the end surface 11 of the wind panel 10 and the front side chamfered portion 12 to the back surface of the wind panel 10, and the portion joined to the back surface of the wind panel 10 has a back engaging portion 32. have. Further, as shown in FIGS. 2 to 4, the molding body 31 is elastically deformed into a curved shape on the peripheral wall surface 2 of the window frame portion on the side facing the peripheral wall surface 2 of the window frame portion of the vehicle body panel 1. An elastic lip portion 33 that is in close contact is formed. On the top portion 34 of the molding 30, on the side of the wind panel 10 facing the front side chamfered portion 12, a terminal covering portion 36 projecting toward the front side chamfered portion 12 is formed simultaneously with the extrusion molding of the molding 30. The terminal covering portion 36 is in contact with and joined to the front side beveling portion 12, and the tip of the terminal covering portion 36 extends to the boundary line between the surface of the wind panel 10 and the front side beveling portion 12.

In the first embodiment, the terminal covering portion 36 of the top portion 34 is formed of a transparent synthetic resin material, and the top portion 34 and the molding body 31 excluding the terminal covering portion 36 are formed of a colored opaque synthetic resin material. Is molded. As the transparent synthetic resin material, for example, transparent P
A VC (vinyl chloride) material is used, and as the colored opaque synthetic resin material, a PVC (vinyl chloride) material colored black or the like is used. When a transparent PVC (vinyl chloride) material is used, it is desirable to mix an ultraviolet absorber to improve weather resistance. Examples of the transparent synthetic resin material include a transparent ionomer resin material in addition to the transparent PVC (vinyl chloride) material.
In the case where this transparent ionomer resin material is used, the terminal covering portion 36 is integrally welded from the top portion 34 and overhangs by using the ionomer resin material colored black or the like as the colored opaque synthetic resin material. It is molded and the terminal covering portion 36 does not peel off unexpectedly.

The window panel provided with the molding of the first embodiment is configured as described above. Therefore, the front side chamfer 12 on the end face 11 of the wind panel 10
When the chamfer angle, the chamfer width, etc. change unexpectedly in the longitudinal direction of the end face 11 of the wind panel 10, the terminal covering portion of the molding 30 coincides with the boundary line between the surface of the wind panel 10 and the front side chamfer 12. The boundary line between the tip of 36 and the surface of the wind panel 10 meanders. However, since the terminal covering portion 36 is formed of a transparent synthetic resin material, the meandering boundary line does not stand out. As a result, the problem that the appearance is deteriorated by the meandering boundary line is eliminated.

Next, an extrusion die device 70 for extruding a window panel provided with the molding of the first embodiment will be described with reference to FIGS. In FIG. 6, a die body 73 of an extrusion molding die device 70 has a first material flow path 75 for a first material 74 which is a colored and opaque synthetic resin material, and a second material 76 which is a transparent synthetic resin material. A second material flow path 77 is formed, and an inlet of the first material flow path 75 supplies a first material 74 to the first material flow path 75.
An extruder 71 is connected, and a second extruder 72 that supplies a second material 76 is connected to an inlet of the second material flow channel 77.

As shown in FIG. 6 and FIG.
An insertion port 78 into which an end of the wind panel 10 is inserted by a required amount is formed on one side surface of the die body 3, and the first material flow path 75 and the second material flow path 77 are formed on the front surface of the die body 73. A feed path 79 that opens with the partition wall 85 is formed, and the feed path 79 opens to the insertion port 78. A die body 81 having a forming path 83 communicating with a feeding path 79 is attached to the front surface of the die body 73 by bolts 80. The base body 81 is formed with an insertion opening 82 into which the end of the wind panel 10 is inserted into a molding path 83 by a required amount. When the end of the window panel 10 is inserted over the insertion port 78 of the die body 73 and the insertion port 82 of the base body 81, the exit of the molding path 83 corresponds to the cross-sectional shape of the molding 30. Extrusion port 8
4 are formed.

As shown in FIG. 7, a part of the periphery of the wind panel 10 is inserted over the insertion port 78 of the die body 73 and the insertion port 82 of the base body 81. Thus, an extrusion port 84 having a molding space corresponding to the cross-sectional shape of the molding 30 is formed in the molding path 83 of the base body 81. In addition, a heat-reactive adhesive is previously applied to the end surface 11 of the peripheral portion of the wind panel 10 and both front and rear surfaces near the end surface 11 as necessary.

On the other hand, the molten first material 74 sent from the first extruder 71 to the first material flow channel 75 of the die body 73 and the molten first material 74 sent from the second extruder 72 to the second material flow channel 77. As shown in FIG. 8, the second material 76 is supplied to the feeding path 79 via the partition wall 85 and merges in the forming path 83. Then, at substantially the same speed as the extrusion speed of the molten first material 74 and the second material 76, the end of the wind panel 10 is relatively moved with respect to the extrusion die device 70, whereby the wind panel 10 is moved. In the longitudinal direction (peripheral portion) of the end portion, the top 34 excluding the terminal covering portion 36 and the molding body 31 are integrally extruded with the first material 74, and the end face 11 and the back face of the wind panel 10 are formed. The molding body 31 is joined over the take-up portion 13 and the back surface.

The end covering 36 is made of the first material 74.
At the same time as the top portion 34 except for the above and the molding body 31 are integrally extruded, the terminal covering portion 36 is
The material 76 is integrally extruded from the top portion 34 so as to protrude from the front side beveled portion 12 of the wind panel 10, and the terminal covering portion 36 is joined to the front side beveled portion 12. By extruding the molding 30 at the end of the window panel 10 as described above, the window panel having the molding described in the first embodiment can be easily manufactured.

The first material 74 and the second material 7 which are molten
6 at substantially the same speed as the extrusion speed of
A state in which the window panel 10 is held by, for example, a panel holding device attached to a six-axis control robot arm in order to move the end surface 11 of the “0” relative to the extrusion port 84 of the extrusion die device 70. By driving and controlling the robot based on the set program, the end face 11 of the wind panel 10 is accurately moved with respect to the extrusion port 84 of the extrusion die apparatus 70 to extrude the molding 30. be able to.
