A unique dynamic seal assembly is used in a mold structure for encapsulating a glass window assembly with a gasket. The seal assembly resiliently supports the window assembly and cooperates with the mold structure for defining a gasket forming cavity. The mold structure typically includes two cooperating mold sections, each of which can be provided with a groove for receiving a separate dynamic seal assembly. Each seal assembly includes a first sealing body having a sealing surface which faces and is adapted to sealingly contact the window assembly. The first seal element is formed of a non-deformable, non-compressible material and is connected to a second seal element formed of a deformable, non-compressible material which is responsive to pressure applied to the first seal element for adjusting the position of the first seal element in the mold to accommodate thickness variations in a window assembly contacting the first surface. The first seal element is typically formed of a Teflon material and is movable in a vertical direction to accommodate thickness variations in a window assembly contacting the first sealing surface. The second seal element is formed of a silicone rubber material or is a tube filled with a non-compressible fluid. |
