Abstract
An apparatus (10) for forming the outer layers of a glass laminate sheet comprises a reservoir (12), individual first (14a) and second (14b) distributors extending below and in fluid communication with the reservoir, and first (30a) and second (30b) slots positioned respectively at the bottom of the first and second distributors. The slots have a length, the distributors have sides and a middle, and the length of the slots on the sides of the distributors is desirably decreased relative to the length of the slots in the middle of the distributors. The apparatus is useful with a trough or isopipe (100) to provide clad glass streams to contact an overflowing core glass on respective sides of the trough or isopipe.
