A method of manufacturing a panel unit having a curved panel and a directly extruded molding. The peripheral edge of the curved panel is moved relative to an extrusion port of an extrusion molding die and a resin molding material is simultaneously extruded directly onto a peripheral edge of the curved panel. While extruding the molding material, the peripheral edge of the curved panel is tilted in response to movement of the curved panel relative to the extrusion port in order to maintain a constant angle between the peripheral edge of the curved panel and the extrusion port.

1. A method of manufacturing a panel unit having a curved panel and a directly extruded molding, comprising: moving either one of the curved panel and an extrusion molding die with respect to the other of the curved panel and the extrusion molding die so that a peripheral edge of the curved panel mo
1. A method of manufacturing a panel unit having a curved panel and a directly extruded molding, comprising: moving either one of the curved panel and an extrusion molding die with respect to the other of the curved panel and the extrusion molding die so that a peripheral edge of the curved panel moves relative to an extrusion port of the extrusion molding die and simultaneously extruding a resin molding material directly onto the peripheral edge of the curved panel; while extruding the molding material, maintaining an angle between the peripheral edge of the curved panel and the extrusion port constant during the relative movement between the curved panel and the extrusion port, stopping the extrusion of the molding material when the directly extruded molding is formed along almost the entire peripheral edge of the curved panel, and eliminating an irregular portion of the directly extruded molding, wherein a gap is formed between a first and second terminal end of the directly extruded molding that exposes a portion of the peripheral edge of the curved panel. 2. A method as in claim 1, wherein the extruding step further comprises moving the peripheral edge of the curved panel along a predetermined path relative to the extrusion port, wherein the directly extruded molding has a predetermined external dimension, even if the external dimension of the curved panel varies from an ideal external dimension. 3. A method as in claim 1, further comprising continuously moving the peripheral edge of the curved panel relative to the extrusion port of the extrusion molding and simultaneously bonding the molding material to the peripheral edge of the curved panel. 4. A method as in claim 1, further comprising connecting the first and second terminal ends of the directly extruded molding with an additional molding. 5. A method as in claim 1, further comprising mounting an additional molding piece in the gap, wherein the directly extruded molding and additional molding piece together extend around the entire peripheral edge including four corners of the curved panel. 6. A method as in claim 1, wherein the curved panel is an automobile window glass. 7. A method as in claim 6, further comprising continuously moving the peripheral edge of the automobile window glass relative to the extrusion port of the extrusion molding and simultaneously bonding the molding material to the peripheral edge of the automobile window glass. 8. A method as in claim 7, further comprising mounting an additional molding piece in the gap, wherein the directly extruded molding and additional molding piece together extend around the entire peripheral edge including four corners of the automobile window glass. 9. A method as in claim 1, wherein the peripheral edge of the curved panel is disposed proximally to the extrusion port during the extrusion molding step. 10. A method as in claim 9, wherein the peripheral edge of the curved panel is inserted into the extrusion port during the extrusion molding step. 11. A method as in claim 10, wherein the curved panel is an automobile window glass. 12. A method as in claim 11, further comprising continuously moving the peripheral edge of the automobile window glass relative to the extrusion port of the extrusion molding and simultaneously bonding the molding material to the peripheral edge of the automobile window glass. 13. A method as in claim 12, further comprising mounting an additional molding piece in the gap, wherein the directly extruded molding and additional molding piece together extend around the entire peripheral edge and four corners of the automobile window glass. 14. A method as in claim 1, wherein the extrusion port is fixed in position and the peripheral edge of the curve panel moves with respect to the extrusion port. 15. A method as in claim 14, wherein the peripheral edge of the curved panel is disposed proximally to the extrusion port during the extrusion molding step. 16. A method as in claim 15, wherei n the peripheral edge of the curved panel is inserted into the extrusion port during the extrusion molding step. 17. A method of manufacturing a panel unit including a curved window glass panel, and a frame mounted on a peripheral edge of the curved window glass panel, comprising: providing a molding die having an extrusion port for extruding a molding material to form the frame, wherein the extrusion port has an inner circumferential surface that corresponds to an outer cross section of the frame; disposing the peripheral edge of the curved window glass panel proximally with respect to the extrusion port in order to form a molding space defined by the peripheral edge of the curved window glass panel and the inner circumferential surface of the extrusion port, wherein the molding space corresponds to the cross section of the frame; extruding the molding material into the molding space; controllably maintaining an angle between the peripheral edge of the curved window glass panel and the molding die constant; continuously moving either one of the curved window glass panel and the molding die with respect to the other of the curved window glass panel and the molding die in order to continuously extrude the molding material along the peripheral edge of the curved window glass panel, thereby forming a directly extruded molding, stopping the extrusion of the molding material when the directly extruded molding is formed along almost the entire peripheral edge of the curved window glass panel, and eliminating an irregular portion of the directly extruded molding, wherein a gap is formed between a first and second terminal end of the directly extruded molding that exposes a portion of the peripheral edge of the curved window glass panel. 18. A method as defined in claim 17, wherein the peripheral edge df the window glass panel moves along a predetermined orbital path with respect to the molding die, and wherein the panel unit has a predetermined external dimension that does not depend upon the external dimension of the panel.
