  • Method of producing glass edge multiple glazed units
    Patent number: 4350515
    Abstract: A glass edge multiple glazed unit having fillets of substantially uniform thickness is produced by the application of heat to marginal edge portions of adjacent sheets, followed by a delay sufficient to establish a substantially uniform, greater than fusing temperature condition in the body of fillet-forming glass. The fused sheets are thereafter drawn apart a preselected distance to a spaced-apart face-to-face relation to form a glass-edge multiple glazed unit.
