Abstract:
1. A glass forming apparatus, comprising: first peripheral walls defining an inner forming space for forming molten glass into a glass ribbon by surrounding a lateral periphery of the inner forming space and having a lower opening at a lower end thereof; a forming body for causing the molten glass to flow downward to form the molten glass into the glass ribbon, provided within the inner forming space; second peripheral walls provided under the first peripheral walls with an interval therebetween that define an inner forming space for receiving the glass ribbon by surrounding a lateral periphery of the inner forming space and having an upper opening through which the glass ribbon passes; a pair of rollers provided within the second peripheral walls for pinching and drawing the glass ribbon downward; partitioning plates having base ends fixed to inner surfaces of the first peripheral walls and distal ends positioned lower than the base ends, for adjusting a temperature within the inner forming space; box shaped trays having open portions; and a tray holding mechanism that enables the trays to enter and exit the interval and that holds the trays such that they are positioned under the distal ends of the partitioning plates and extend along the distal ends when the trays are within the interval.
