Abstract
This invention involves a method of using deairing rings comprising flexible channel members of a novel construction around the periphery of an assembly of glass and flexible plastic sheets during its lamination and the construction of said novel deairing rings. The deairing rings are readily applied to and removed from the assemblies to be laminated and are so constructed as to facilitate the lamination of large windows, particularly those having sharp corners.
