Abstract
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.
