Described herein are glass forming apparatuses with cooled muffle assemblies and methods for using the same to form glass ribbons. According to one embodiment, a muffle assembly for a fusion forming apparatus may include a muffle frame comprising a back wall, a front wall opposite the back wall, and a pair of sidewalls joining the front wall to the back wall in a closed-loop. At least one first cooling tube may extend through the back wall and the front wall across the closed-loop. At least one second cooling tube may extend through the back wall and the front wall across the closed loop such that the at least one second cooling tube is spaced apart from and parallel with the at least one first cooling tube.

Glass forming apparatuses and methods for making glass ribbons

A system includes an overflow distributor and a support member. The overflow distributor includes a first sidewall, a second sidewall opposite the first sidewall, and a floor extending between the opposing first and second sidewalls. Interior surfaces of the first sidewall, the second sidewall, and the floor cooperatively define a trough configured to receive molten glass. Exterior surfaces of the first sidewall and the second sidewall are configured to direct molten glass that overflows the trough. The support member is disposed between the opposing first and second sidewalls of the overflow distributor and abutting an exterior surface of the floor of the overflow distributor.

System for forming a glass article

The disclosure relates to apparatuses for producing a glass ribbon, the apparatuses comprising a forming body () comprising an upper trough-shaped portion comprising two trough walls and a trough bottom; a lower wedge-shaped portion; a delivery end configured to receive molten glass; and a compression end () comprising a curb (); and an end cap () coupled to the compression end () and extending over a top surface of the curb (), wherein a height of the curb () is greater than a height of the two trough walls at a point proximate the compression end (). Also disclosed herein are methods for producing a glass ribbon using such apparatuses. This minimizes glass flow into the end cap and over the compression end of the forming body and minimizes formations of gobs.
