System for forming a glass article

A system comprising:

• a first overflow distributor comprising a first sidewall, a second sidewall parallel and opposite the first sidewall, a floor disposed between the opposing first and second sidewalls, a trough disposed above a top surface of the floor and between the opposing first and second sidewalls and extending in a transverse direction within the overflow distributor, and interior surfaces of the first sidewall and the second sidewall and a bottom surface of the floor cooperatively defining a cavity disposed beneath the floor and extending in the transverse direction within the first overflow distributor, the trough and the cavity separated by the floor, wherein portions of the interior surfaces of the first and second sidewalls that define the cavity extend parallel to one another beneath the bottom surface of the floor;
• and
• a support member disposed within the cavity;
• and
• a second overflow distributor arranged below the first overflow distributor.

A system comprising:

• an upper overflow distributor comprising a first sidewall, a second sidewall parallel and opposite the first sidewall, a floor disposed between the opposing first and second sidewalls, a trough disposed above a top surface of the floor and between the opposing first and second sidewalls and extending in a transverse direction within the upper overflow distributor, and a cavity disposed beneath a bottom surface of the floor and between interior surfaces of the opposing first and second sidewalls and extending in the transverse direction within the upper overflow distributor, the trough and the cavity separated by the floor, wherein portions of the interior surfaces of the first and second sidewalls that define the cavity extend parallel to one another beneath the bottom surface of the floor;
• a lower overflow distributor disposed beneath the upper overflow distributor and comprising a first sidewall, a second sidewall opposite the first sidewall, and a trough disposed between the opposing first and second sidewalls and extending in the transverse direction within the lower overflow distributor, the opposing first and second sidewalls converging at a draw line disposed beneath the trough of the lower overflow distributor;
• and
• a support member disposed within the cavity of the upper overflow distributor.
