Method of fabricating window panels, particularly curved panels
First Claim
1. A method of fabricating a curved, laminated transparency panel having a curved, rigid mounting frame surrounding a curved, laminated transparency provided with transparent elements and also including a curved, metal reinforcing insert having an inner portion embedded therein and an outer portion bonded to said frame comprising first applying bonding means to an interfacial surface between said frame and said insert, then assembling said frame and said insert on opposite sides of said bonding means to bond the outer portion of said insert to said frame to form a curved sub-assembly with the inner portion of said curved insert extending inwardly of said curved frame, thereby enabling the bond between said curved frame and said outer portion of said curved insert to reinforce the inner portion of said insert, then assembling the elements of said curved, laminated transparency to the inner portion of said curved insert, and laminating said curved assembly so formed with minimum movement of said inner portion relative to the thickness of said transparency elements during said latter laminating step.
