Abstract
The invention relates to a glass plate having a molding formed on a peripheral edge thereof. The present invention provides an extrusion die having first and second void spaces formed therein. The first void space is provided for supplying an adhesive to the peripheral edge, and the second void space is provided for supplying a molding material to the peripheral edge. The first and second void spaces are specifically arranged relative to each other. With this, while the glass plate is moved relative to the extrusion die, the molding is extruded on the peripheral edge simultaneously with the formation of the adhesive layer on the peripheral edge. Thus, the formations of the molding and the adhesive layer are conducted in one production process. With this, the production efficiency is much improved. The present invention further provides a glass plate having an adhesive layer made of a thermoplastic hot melt adhesive and a molding made of a thermoplastic resin, which are formed on a peripheral edge of the glass plate. In the process for producing this glass plate, the heated thermoplastic resin having a specifically controlled temperature is brought into contact with the heated thermoplastic hot-melt adhesive having a specifically controlled temperature. With this, at a boundary between the adhesive layer and the molding, the thermoplastic hot melt adhesive and the thermoplastic resin are fused together and blended with each other. With this, bond strength of the molding to the glass plate is much improved.
