Method and apparatus for forming glass laminates comprising plies with offset edges

A process for fabricating a glass laminate, the process comprising:

• positioning a second glass substrate onto a first glass substrate with a polymeric material between the first glass substrate and the second glass substrate to form a stack, wherein the first glass substrate comprises a greater surface area than the second glass substrate such that the first substrate comprises an extending portion that is not covered by the second glass substrate and an edge of the first glass substrate is offset from an edge of the second glass substrate by a distance that is greater than or equal to 10 mm;
• inserting an entirety of a periphery of the stack into a vacuum channel of a vacuum ring, wherein the vacuum ring comprises 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 greater than or equal to twice the first depth, wherein an entirety of the extending portion is contained in the second portion of the vacuum ring;
• applying negative pressure to the vacuum channel;
• and
• heating the stack to above a softening temperature of the polymer material to bond the first glass substrate to the second glass substrate such that the second glass substrate is retained in a bent shape by the first glass substrate and the polymer material.
