Zusammenfassung:	Methods and apparatuses for fabricating glass laminates where there is a substantial offset between edges of glass plies of the laminates are described herein. The method includes placing an entirety of the periphery of a stack of the glass plies in a vacuum ring comprising a vacuum channel with a depth that circumferentially varies. The vacuum ring includes at least a first portion where the vacuum channel has a first depth and a second portion where the vacuum channel has a second depth that is at least two times greater than the first depth to accommodate edge offsets. Negative pressure can be applied to a space between the plies via the vacuum ring to deair the space. A suitable furnace can be used to bond the plies together and form a laminate having a desired shape.
