Abstract: In molding a gasket on a window glass, a dummy member having a peripheral portion the shape of which is the same as the peripheral portion of a window glass which is intended to be provided with a gasket, is placed in a molding device having a gasket forming cavity. A gasket material is injected into the cavity formed at the peripheral portion of the dummy member and solidified. The dummy is removed from the molding device, after which the gasket is separated from the dummy member and attached to the peripheral portion of a window glass.

Abstract: A method for bending glass plates comprises a step of softening by heating at least two glass plates placed in an overlapping state on a bending ring mold to shape them in a curved form by their own deadweight in a processing zone of a heating oven, a step of pressing the at least two overlapped glass plates from the top, which are bent or being bent in a predetermined form by their deadweight on the bending ring mold, by a pressing mold in a pressing zone in the heating oven or in the pressing zone under heating condition which is connected to the heating oven, and a step of gradually cooling the at least two glass plates in a cooling zone outside the heating oven.
