Patent ID: 7685841

Claim:
A method of making a glass sheet comprising: flowing a molten glass over a pair of downwardly inclined forming surface portions comprising a forming wedge, the downwardly inclined forming surface portions converging at the bottom of the forming wedge; flowing the molten glass over a web surface portion intersecting with at least one of the pair of forming surface portions, the web surface portion comprising a first surface normal; flowing the molten glass over an extension surface portion intersecting the web surface portion and extending below the bottom of the forming wedge, the extension surface portion having a second surface normal, and wherein the first surface normal and the second surface normal lie coplanar in a first vertical plane passing through the web surface portion and the extension surface portion, and an angle between the first and second surface normals is between 15 degrees and 30 degrees; and drawing the molten glass from the forming wedge to form a glass sheet.
