description The disclosure relates to apparatuses for producing a glass ribbon, the apparatuses comprising a forming body (100) 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 (237) comprising a curb (243); and an end cap (205) coupled to the compression end (237) and extending over a top surface of the curb (243), wherein a height of the curb (243) is greater than a height of the two trough walls at a point proximate the compression end (237). 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.
