Vacuum Ring For Producing Laminated Glass Abstract The present invention relates to a unique vacuum ring construction which can be utilized to de-air a laminated glass assembly while it is positioned within a pressurized and heated autoclave unit. The vacuum ring is constructed to minimize the amount of plastic material which can flow outwardly of the marginal edges of the glass sheet during the heating and pressurizing operation of the autoclave. The ring is provided with a channel formed therein for receiving the peripheral edge of the laminated assembly. In accordance with the present invention, at least a first length of the channel defines an inner surface having a cross-sectional configuration which generally conforms to the cross-sectional configuration defined by the outer edge surface of the laminated assembly when the ring is mounted on the laminated assembly and coupled to a vacuum source. At least a second length of the channel is provided with a recess which is positioned adjacent the juncture of the edges of the individual laminae when the ring is mounted on the laminated assembly. The recess is defined by a wall at least a portion of which is maintained in spaced apart relationship with the laminated assembly when the ring is coupled to the vacuum source.
