Laminated glass ribbons and apparatuses for forming laminated glass ribbons

An apparatus for making a glass ribbon, the apparatus comprising:

• an upper forming body comprising an outer forming surface bounded in a lateral direction by a pair of upper dams, the upper dams spaced apart from one another to define an upper dam space extending across the outer forming surface of the upper forming body;
• a lower forming body disposed downstream of the upper forming body and comprising an outer forming surface bounded in a lateral direction by a pair of lower dams spaced apart from one another to define a lower dam space extending across the outer forming surface of the lower forming body;
• and
• an edge guide disposed along an interior upper dam wall of the pair of upper dams, the edge guide having a shape that is flared laterally outwardly from the interior upper dam wall,
• wherein the outer forming surface of the upper forming body is spaced from the outer forming surface of the lower forming body by an interior gap,
• wherein a portion of the upper forming body exterior to the outer forming surface of the upper forming body and separate from the upper dams is joined to a portion of the lower forming body exterior to the outer forming surface of the lower forming body and separate from the lower dams,
• wherein at least one of the following items is satisfied:
• a) a width of the upper dam space is different from a width of the lower dam space;
• or
• b) interior upper dam walls of the pair of upper dams are aligned with interior lower dam walls of the pair of lower dams such that a pair of common dams extends from the upper forming body to the lower forming body, and
• wherein the interior gap is disposed between and within the wider of the upper and lower dam spaces.
