Abstract: 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.

Abstract: The present invention relates to an improved mold structure for forming a polymeric gasket around a predetermined portion of a frangible sheet such as glass. The mold structure includes two cooperating mold sections having spaced apart facing surfaces for defining a chamber for receiving the glass sheet. A seal is positioned in at least one of the mold sections about the periphery of the chamber and is utilized to resiliently support the sheet within the chamber. The seal cooperates with the mold sections and a predetermined portion of the sheet for defining a gasket forming cavity having a configuration corresponding to the gasket to be formed on the sheet of the material. An inlet communicates with the gasket forming cavity and is utilized to introduce a flowable gasket material into the gasket cavity.
