Methods for preparing a panel unit having a panel and a frame in which a first molding piece is formed by engaging an extrusion port of an extrusion molding die with a peripheral edge of the panel and extruding an extruded molding material along the peripheral edge of the panel. The extruded molding material preferably simultaneously bonds to the peripheral edge. Waste pieces may be eliminated from the first molding piece after bonding the first molding piece to the peripheral edge and the frame may be completed by adding an additional molding piece to provide a continuously formed frame around the peripheral edge. The first molding piece may be formed by continuously moving the peripheral edge relative to the extrusion port in a predetermined orbital path. The peripheral edge of the panel may be subjected to a primer treatment before engaging the extrusion port.

[ What is claimed is:] [1.]1. A method of manufacturing a window unit for a vehicle front window, comprising:engaging an extrusion port of an extrusion molding die with a lower peripheral edge of a glass window and extruding a molding material along the peripheral edge of the glass window the extruded molding material simultaneously bonding to the peripheral edge and thereby forming an in situ molding,stopping the extrusion of the molding material when the in situ molding is formed along almost the entire peripheral edge of the glass window, wherein the in situ molding is continuously formed around three sides of the glass window andeliminating an irregular portion of the in situ molding to form a first terminal end and a second terminal end of the in situ molding, wherein a gap is formed between the first and second terminal ends that exposes a portion of the peripheral edge of the lower portion of the glass window.
