Abstract
Forming defects and cracks caused by agglomerated glass components are prevented in a glass forming apparatus, such as a fusion draw glass forming apparatus. The glass forming apparatus has first peripheral walls; a forming member to form the glass into sheet form; second peripheral walls provided beneath the first peripheral walls with an interval therebetween; rollers provided within the second peripheral walls for drawing the glass in sheet form downward; partitioning plates for adjusting the temperature of the space; box shaped trays having open portions; and a tray holding mechanism that enables the trays to enter and exit the interval and that hold the trays such that the open portions of the trays extend along the distal ends of the partitioning plates at a position under the partitioning plates when the trays are within the interval.
