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.

Claims

1. A method of making a window glass and gasket assembly comprising the steps of:

preparing a dummy member having a peripheral portion of a certain shape which is the same as that of the peripheral portion of a window glass which is to be provided with a gasket,

putting the dummy member in a shaping mold having a gasket forming cavity,

injecting a gasket material into the cavity formed at the peripheral portion of the dummy member and solidifying the gasket material with said certain shape,

removing from the mold the dummy member around which a gasket is formed, said gasket having a recess at a portion thereof facing the dummy member,

attaching the gasket to the peripheral portion of the window glass with an adhesive applied between the window glass and the gasket.

2. The method according to claim 1, wherein a fitting piece adapted to attach a window glass assembly to a structure is previously arranged adjacent the peripheral portion of the dummy member and the gasket material is injected in the cavity, whereby a one piece body of the gasket and the fitting piece is formed.

3. The method according to claim 1, wherein a recess for receiving a fitting piece for attaching the window glass to a structure is formed in at least a part of the gasket.

4. The method according to claim 1, wherein a recess for receiving a fitting piece for attaching the window glass to a structure is formed in at least a part of the gasket, followed by bonding the fitting piece to one of the gasket and the window glass together with the gasket.
