Claims
- 1. A production method for extruding molding sections to be fitted along a periphery of a windshield glass, which comprises:
- extruding said molding sections by using a die having an opening for extruding a support leg for being inserted into a space between the windshield glass and a window frame of a body panel and also having an opening for extruding a decorative portion which covers the space from outside the molding sections, wherein said molding sections are extruded by keeping an area of the extrusion opening on the die for the decorative portion constant at all times, and
- increasing, at least during production of one of the molding sections, an area of the extrusion opening on said die for extruding said support leg to provide an enlarged thickened section between an outer surface of the windshield glass and the decorative portion.
- 2. The production method as claimed in claims 1, which comprises:
- inserting an additional die into an extended section of the extrusion opening on said die for the support leg with specified timing so as to form a rainwater groove on a side wall of said enlarged thickened section.
- 3. The production method according to claim 2, which comprises:
- changing a depth dimension of the rainwater groove by changing positioning of said additional die during extrusion.
- 4. The production method according to claim 2, wherein said molding sections include a side section, which comprises:
- moving the additional die so as to change a depth dimension of said rainwater groove in an end section of the side molding section.
- 5. The production method according to claim 2, wherein said molding sections include a side molding section, which comprises:
- moving the additional die so as to make the rainwater groove shallower and be discontinued in an end section of the side molding section.
- 6. The production method as claimed in claim 2, wherein the additional die has a triangular shape, which comprises:
- changing a width dimension of the rainwater groove so as to become gradually smaller as a depth dimension of the triangular shape of the additional die becomes gradually smaller.
- 7. The production method as claimed in claim 2, wherein the molding sections include a side molding section and the additional die has a triangular shape, which comprises:
- moving the additional die so as to make the rainwater groove become shallower and be discontinued in an end section of the side molding section;
- changing a width dimension of the rainwater groove so as to become gradually smaller as a depth dimension of the triangular shape of the additional die becomes gradually smaller; and
- forming an enlarged thickened section upon moving of the additional die and upon changing of the width dimension of the rainwater groove.
- 8. The production method according to claim 2, which comprises inserting said additional die so as to form said rain water groove by partially shielding said enlarged fixed section.
