Abstract
A method for manufacturing a bilayer or antilacerative windshield comprised of a rigid substrate and an innerliner, including the steps of producing a hole in the innerliner, assembling the rigid substrate and the innerliner together in interfacial relation to each other, and then placing an insert into the hole. Thereafter, the rigid substrate and the innerliner are laminated together to thereby provide the antilacerative windshield, the insert serving to prevent flow of the innerliner into the hole during the laminating step. After the laminating step is completed, the insert is removed from the hole, to thereby open the hole to expose the adjacent surface of the rigid substrate. The mounting pad or 'button' of a rear view mirror is then affixed to the exposed surface of the rigid substrate.
