An encapsulated multiple glazed structure is formed by positioning at least two spaced apart substantially coextensive sheets of glazing material wherein the sheets are maintained in aligned spaced relation by a suitable spacer element adjacent the peripheral portions of the facing surfaces of the glazing sheets. The above assemblage is then typically placed within a mold cavity of a suitable molding apparatus and a charge of an elastomeric gasket forming material is injected therein to form an encapsulating gasket around the peripheral edge portions of the assemblage to produce a multiple glazed structure.

Method of making an encapsulated multiple glazed unit

A fixture for supporting and masking an ecapsulated window assembly includes a generally planar floor having a periphery surrounded by generally upstanding walls. An upper edge of the walls engages an inner surface of a gasket formed on a periphery of the window assembly whereby the fixture masks the inside surfaces of the gasket and a glass sheet forming the window assembly. At least one aperture is formed in the fixture for receiving a reference pin utilized to locate the fixture with respect to a painting apparatus. A sensor is provided for generating a signal representing the engagement of the aperture by the reference pin and a control unit is responsive to the sensor signal for controlling a robot painting apparatus to spray paint an outer surface of the gasket. The fixture further is used to support the window assembly during curing of the paint and subsequent manufacturing operations.

Method of supporting a window assembly

A fixture for supporting and masking a portion of a window assembly during a painting operation includes a lower cover pivotally attached to an upper cover for movement between an open position and a closed position. In the open position, a window assembly can be inserted between the covers and in the closed position the covers mask a glass sheet and expose a gasket of the window assembly for painting. The upper and lower covers can be formed with a generally planar floor surrounded by upstanding walls having recessed portions formed in the sidewalls dimensioned to retain and seal the glass sheet. The lower cover can be hingedly connected to a mounting block for approximately 180.degree. of rotation to expose both sides of the extending gasket to a paint spray apparatus. A latching mechanism can be provided to maintain the upper and lower portions in the closed position during the painting operation. In an alternate embodiment, one of the covers can be a planar sheet and a handle can be provided thereon to assist in the rotation of the fixture about the mounting block.

Article supporting fixture

A glazing unit comprised of a glass substrate and a laceration inhibiting shield supported by and extending over what would otherwise be an exposed surface of the substrate. A gasket or frame member composed of a synthetic polymer extends around a major portion of the periphery of the glass substrate and shield and is adhered to the marginal edge surfaces of each, such gasket having been polymerized in situ adjacent the said periphery and having assumed through the autogenous mechanism incident to its polymerization and cure, while confined intimate contact with the portions to which it is adhered.
