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 sealing body having a sealing surface which faces and is adapted to sealingly contact the window assembly. The seal assembly also includes a first fluid filled bladder positioned between the sealing body and a bottom of the groove in the mold section. When increased pressure is applied to a local area of the seal as a result of a contour difference between the seal and the window assembly, the bladder deforms to automatically transfer at least a portion of the applied pressure to adjacent areas of the seal. A second fluid filled bladder is positioned between the sealing body and a side wall of the groove to force the sealing body against the opposite side wall of the groove. The sealing body can be provided with a strip of Teflon material for sealing against the side wall of the groove. |
